2010 battery list

[DaveG28]

Is up...

5000mah 50C LRP Lipo's... Ridiculous, but I want!!

[DaveG28]

One of the LiFe batteries is 70C ffs!! Anyone got an estimate of what motor would be needed to counteract the lower voltage?

Tempted to try a 3.5 or similar with a LiFe pack in 2wd..

[Darren Boyle]

Some interesting names "missing" from the list too....... may surpirse a few racers who have brought in advance!

Is it me, or are the lists HUGE this year and full of some brands we have never even heard off too.

[Jamie B4]

Dave/Darren,

Where is the list and is this the official BRCA list for 2010, cant see what you are looking at??

[Darren Boyle]

They are, and they are!!

Size creep too, especiall on height of cells!

Think I know why one brand is missing, surprised about some others having no new cells!

[GRIFF55]

Not enjoying looking at that list, gona be an expensive start for me!!:(

Not enjoying looking at that list, gona be an expensive start for me!!:(

Looks like you will have to find a new Lipo sponsor for 2010 :cry: Should of sold them packs last week, I will give you £5 per pack :p

[JohnM]

No Trakpower Dark series, big suprise for me that one, glad I didn't get any!

[chrispattinson]

I cant see these cells offering a significant advantage on the track over my 2009 cells.
Its my first year of doing nationals (hopefully - if I get in), and Im happy with the pace of my car with my 30C 4200mah Demon cells.
Obviously theres more power available from these 2010 cells... but Im not sure it'll drop my lap times by much, unless these national tracks have huge straights....
am I right?

Or do I need to fork out for an LRP 50C pack?

I seriously doubt it, there's so much spare mah that I'd have thought you can make sure you have all the power you ever need without dumping through motors/settings etc!

[dibble34]

No Trakpower Dark series, big suprise for me that one, glad I didn't get any!

I did buy a set. I read on here somewhere that they had applied to be on it. I wonder why they are not on there, must be a reason.

[MatJohnson]

Good news for me Jamie, them 45c's I've got are legal :)

you are completely right, in off-road you don't even use the fastest motors available. as long as you know your packs are reliable then you will be fine.

Im pretty sure ive had the fastest car on the track at a few nationals and didn't win with it

[coolcars782]

Remember Consistency not speed is better, although speed does help a bit :D

[TonyM]

B***er I bought three stick and one saddle. Got rid of my gold ones - stupid idiot!!!

No Trakpower Dark series, big suprise for me that one, glad I didn't get any!

[Kopite]

which ones are the ones missing? (or the ones people expected to be in there)

[Darren Boyle]

The most obviuos absentee is the Trakpower Darks.....

[hide]

50C SMC packs are legal, good as I was about to buy some.

[budgio]

I,m not sure if this has been asked before but will any more packs be added to the 2010 BRCA legal list over the next few weeks/months ? or is it final ?
Just curious as it seems BRCA legal brushless motors list gets updated throughout the year.

[JohnM]

The most obviuos absentee is the Trakpower Darks.....

Does anyone know why this is yet? seems odd after the way they sorta facelifted the old gold ones for last years list, then made a big noise about how potent the Dark series are.

Just curious as it seems BRCA legal brushless motors list gets updated throughout the year.

The battery lists (LiPo, NiMh, LiFe etc) all only get new cells added once a year, which is currently April 1st (submission deadline Dec 31st). As you rightly say, the motor lists are updated on average monthly, but can be as often as required.

[_sleigh_]

Does anyone know why this is yet? seems odd after the way they sorta facelifted the old gold ones for last years list, then made a big noise about how potent the Dark series are.

Don't know the full reason, however they could have been oversized or even failed the safety drop test. You never know, they could have missed the Dec 31st deadline or not even submitted them.

[dibble34]

I have emailed Trakpower asking why the Dark Series are not on the list. If i get a response i'll let you know

[Matt_N]

Don't know the full reason, however they could have been oversized or even failed the safety drop test. You never know, they could have missed the Dec 31st deadline or not even submitted them.
Trakpower Dark's are the same as the Robitronic 5000mah 40C afaik, which is on the list :confused: Oh well, I'm not too fussed, my SMC 5200mah 50C is on the list :D

Matt

[Jamie B4]

Major thankyou to Mr Worsley - list out in plenty of time for next season - now means there are no excuses for not being ready for oncoming 2010 nationals. Thanks Jamie

[wizzykev]

Is there anything in the rules that stops us from changing the connectors on a lipo. I've got a GM saddle pack and I want to change the connectors.

What you guys think?

Cheers

[Marvin]

Wow, a long list of made up ratings. If an LRP 40C pack doesn't compare to others' 35C packs, how can anyone expect that their 50C pack will be near accurate?

A few brands are getting guilty of this, LRP/Nosram, SMC, even (sigh...) Thunderpower...

Ignoring the absolute c rating for a moment, and making it absolutely clear I don't think further increases are needed performance wise, presumably they have improved the cells, or are you suggesting they are just putting them in bigger cases to trick people??

Can't see the latter, not a good sales technique to deliberately make them nit fit some cars so I'm guessing it's a necessary size increase!

Not saying it's not 30-40c rather than 40-50c mind, tbh I wouldn't know!

[Benh]

With regards to the TP Darks I am going to take punt in the dark here. Be clear, this an assumption based on ZERO fact.

I think, that they didn't submit.

Why - For the first time they used OEM, to meet the market demands, which meant (possibly) comprimising on standard. With an apparantly tight market (look how many are on the lists!), the ROI, (with assumed MOQ) was not sufficient to compromise a brand name like TP.

Why do I think the above -

Reading this: - http://www.flightpower.co.uk/ on the front page of the website. ( should it move it's here too http://www.flightpower.co.uk/newsOpenArticle.asp?submit=Open&articleID=201&parentPage=newsArchive.asp )

I reckon they'll re-emerge in the Track market with something exciting.

No facts, just a thought?

totally wrong sorry (apart from your last sentance in bold)

there is a clue in the latest RRCI advert!
as and when i can say more i will

[Jackal]

wonder when trakpower are going to explain to everyone who bought the dark series why they cant use them at the nationals or euros or regionals or any sanctioned event and what they intend to do about it.

[sldmodels]

At least as far as Trakpower goes, there's been a management buyout, so that could have caused problems for submitting cells.

I know there should be some LRP micro lipos on there at some point, but at the submission date, SMD we're out of stock on them so couldn't submit them at the time, but I think they'd gotten the paperwork sorted, so hopefully they should be added at some point this year.

You could ask Paul why a certain lipo isn't on the list, but I'd think the obvious reason would be that it wasn't submitted or failed the test, and I think Paul might be a bit too happy to field hundreds of emails from angry racers.

[mark christopher]

ask the question........... were they advertized as being BRCA legal?

Answer No, as every one says every year, You have to wait for the list to be sure!

you cant add lipos throughout the year, the list is fixed now. i know why the dark series are not on the list, the question is what are trak power going to do about the unhappy and out of pocket customers?

your absolutely correct you wait until the list comes out or take a risk, that isn't the point, assuming you are as "in touch" with them as you make out, you know why they are not on the list, so when are they going to say something

you have not been misslead in anyway that they would be BRCA legal?? thier claim is ther designed to meet the requirments, which they do!

i do know, when i can say more i will, for now its not my place to say, but for now look at the advert in the latest RRCI and work it out!

What would annoy me is if TP never had any intention of applying for BRCA status for the Dark Series. They would of known full well that a lot of people would get them before for Christmas etc in the assumption (right or wrong) it was looking likely they would be legal. If this was the case they should of made it clear from day 1. I have had no response to the email i sent TrakPower although i guess that may of had quite a few.

I did read all the posts, can't see any mention that they did submit an application. I don't have access to RCCI, the fact remains unless they give a really good reason then they will of lost a lot of future business, regardless of what name they trade under

as and when i can say more i will

same again as i have asked this already

where did they say they were BRCA legal?

[LEE-HO]

The lack of Track power dark cells will make it so that I cannot afford to race this year.

In the run up to Xmas where the only top brand lipo's in local shops.

This hobby is far to expenisve for club level racers, and the lack of this cells will make it so many club level drivers like me will be unable to race this year.

[TonyM]

I think the point is that people expected TrakPower to submit and be on the list. A reasonable assumption as the gold series were and a hell of a lot of people raced with them. If they were a new or unknown brand then it would be right to condone people for making too many assumptions. But, I think it reasonable for people to assume TrakPower would be on the 2010 list.


same again as i have asked this already

where did they say they were BRCA legal?

[DaveG28]

I think they intended to be on the list, given they'd signed up some national drivers (or, and this may be the key bit, the uk distributor did).

I'm taking an educated guess, part of being brca legal is proving the cells will be commercially available within the uk, with the ownership/distribution changes I think maybe they couldn't do so in the timescale involved for the list completion.

[Dazzler]

Is it a case that TrakPowers were submitted, but as they appear to be re-branding to TrakTech, then the Trakpowers would therefore be no longer available so they simply could not be put on the list. And I guessTraktech were not available in time for submission...

[Col]

This is utterly ridiculous!!
It's the same every year.
If you intend to race at BRCA sanctioned events and you buy your cells before the list is out then you deserve your to loose your money.
It's irrelevant why TP Dark's are not on the list - the simple fact is that they aren't. If anyone was serious about the 2010 year then all you had to do was ask around and anyone with 1/2 a brain would have said wait for the list.

So just so I can quote this post next year in an identical thread to this one ONLY BUY YOUR LIPO'S AFTER THE LIST IS RELEASED. NEVER BUY BEFORE CHRISTMAS. NEVER MAKE ASSUMPTIONS.

[MikePimlott]

Col, You've just said what loads of people were thinking. :thumbsup:

[Col]

I'm sorry, it just winds me up.

[DaveG28]

Col, not sure why it isn't ok to discuss why a major brand is missing???

I agree people should wait for the list, no reason not to this year either as if you "needed" cells before now you can just use the 2009 list as it carries forward.

That doesn't mean it isn't of interest when a major cell brand who produced new cells recently hasn't gone on the list?

[Benh]

I haven't bought the TP Darks. Was going too but waited for the list.

Is it not ok to have a punt and discuss - that what forums are for? As long as we don't spout sh'te as if its the truth, what harm is there. I like TP, I like their products and am just surprised. Thats all.

I'll get my jacket.....

I agree this is the bottom line, but i think your comments are a little harsh. If you have loads of money and can by what you need fair enough. I am lucky enough now to be able to buy some more LIPOS now, however at Christmas i needed to ask for some as it looked like the only time i would be able to switch to LIPO for this year. the TP Dark Series looked a good bet to be on this years list so i took a chance. I am sure other people were in a similar predicament. Daves comments further up are very well put.

[Jackal]

just for the record i am not out of pocket because of the lack of trakpower cells, however i asked a question as to what they (TP) intend to do, my reasons for this are as follows, every year as col forcibly states there is some problem with the list and bold statements are made by forum members usually aimed at the BRCA and its officials, some years the comments are justified some not, already there are two threads on this forum about TP Darks and already wild statements are being made. it would be helpful if the company issued a statement rather than let any further damaging comments being made.

what do you expect them to do? what have they done wrong?
they have not sold them as BRCA legal.

[Marvin]

Try not to use TP as an abbreviation of Trakpower - historically that is Thunderpower (who are on the list).

Nice to see Flightpower back to fresh beginnings while Flighttech has moved on to Energon.

At no point did Flightpower (or any of its employees - like Mac on here) actually say or imply that Trakpower's Dark Series were actually going to be BRCA sanctioned, just that everyone kind of assumed that they were going to be. Flighttech was going through a buyout at that time, and getting batteries sanctioned was probably low on the priority list.

No club (surely) requires you to have LiPos that are on the list, unless you do regionals or nationals, at which point surely you must have a fair amount of money to be able to afford doing them?

The company won't issue a statement - and quite rightly - it's nothing to do with them that you assumed.

[simoncook]

I was having a look round the trackpower website, and found this:-


The New TrakPower Dark Series brings the Known quality of The TrakPower range to a new 40c discharge rate.
Designed to meet and exceed B.R.C.A , R.O.A.R and E.F.R.A specifications.

http://www.energonsolutions.co.uk/eshop-product-categorie/1643504/TRAKPOWER-DARK-SERIES-40C-5000MAH-STICK-PACK

Now to me, that implies that Trackpower were reasonably confident that they would be sanctioned and on the list. You can't blame people for reading that and then assuming the cells would be ok.

But I agree, wait for the list, doesn't matter what the manufacturer says.

[ashleyb4]

They said there Designed to match the specifications it doesnt mean there legal no manafacturer can say they are BRCA legal until they have been inspected etc by Paul.

thank you ash, my faith is restorded in you

[sldmodels]

I'm a little worried myself that my lipos seem to have disapeared of the list. I'd assumed that once cell we're on the list, they would stay on the list.

[_sleigh_]

Which cell is that then?

[sldmodels]

Demon DL5000, can't see them anywhere. I'm looking at replacing them anyway, but don't want to be forced into it.

[_sleigh_]

I can't see them being removed if originally on the list. This years list hasn't changed since 27/01/10 and I can't really see Mr Worsley making any mistakes in the homologation checks.

Perhaps they weren't there originally or they go by different part numbers than you think, as there's two Demon sticks that are 5000mAh from last years list.

[sldmodels]

Well just in case ssshhhhhhh! I'm racing tomorrow, and obviously don't have chance to get any replacements lol

[Si Coe]

I must admit it does strike me as a little daft that cell approval only occurs once a year - cell tech moved on quite a lot in the last 12 months or so.
By the start of the winter season there were a lot of people running new cells on the gamble their chosen version would be approved, not just Darkpowers but others too. Ironically given how popular the gold packs were, Darkpowers were regarded as the 'safe' bet to be in.
People got new cells early because they needed new cells. Yes they could have gotten 2009 list cells, but who wants last years 4000mAh 25C when you could have the latest 5000mAh 40C? Buy last years and be at a disadvantage when the new list comes out or go for the new tech and hope its approved.....




Anyway - all that said time to get off Trakpowers case. Sure you might have lost a few quid buying cells that are perfectly good for club meets but not nationals or regionals (and even then you can use them for practice!), but thats nothing compared to what Trakpower have lost. Because I can't imagine them selling many packs this year.......

[DaveG28]

I must admit it does strike me as a little daft that cell approval only occurs once a year - cell tech moved on quite a lot in the last 12 months or so.
By the start of the winter season there were a lot of people running new cells on the gamble their chosen version would be approved, not just Darkpowers but others too. Ironically given how popular the gold packs were, Darkpowers were regarded as the 'safe' bet to be in.
People got new cells early because they needed new cells. Yes they could have gotten 2009 list cells, but who wants last years 4000mAh 25C when you could have the latest 5000mAh 40C? Buy last years and be at a disadvantage when the new list comes out or go for the new tech and hope its approved.....




Anyway - all that said time to get off Trakpowers case. Sure you might have lost a few quid buying cells that are perfectly good for club meets but not nationals or regionals (and even then you can use them for practice!), but thats nothing compared to what Trakpower have lost. Because I can't imagine them selling many packs this year.......

Not too sure how much disadvantaged, at a quick look I'd guess at least half of this years cells won't even fit in a B4 with the standard battery strap. most of them are so high! I might try and grab some more 2009 cells before they disappear!

I thought part of the big idea behind LIPO's and how they were advertised way back in 2008 and 2009 was that they would last longer than the current range of NIMh's so I don't get why people are replacing last years cells?
It's not as if we need any more power, especially in off road.

Still amazes me that this seems to happen every year!!!

Actually the main reason I know of people getting new cells was down to switching cars and going from sticks to saddles or vice versa. Or in the case of Durango runners especially because their existing cells didn't fit.
Which means you need to wait for next years list to buy a new chassis too!

Fair enough answer, thats why I changed my cells, but then I also bought some off the 2009 list.

Col, not sure why it isn't ok to discuss why a major brand is missing???

No problem with that one, dude! I'm actually quite curious myself.

Several points have been raised in this thread about why people had to buy new lipo's and as far as I can remember the only valid one is changing chassis. I've recently gone from stick to saddle so was in the same boat myself (except that this is gonna be another year I don't get to do regionals).
But as so many top drivers have said many time we have too much power in off road these days, so replacing lipo's cos they are a year old is just stupid. I've got a Trakpower 4900 stick pack that's nearly 3 years old and has as much punch now as it did new. It's almost a shame to retire it!
My latest are Intellect 4200 saddles. I have one set that will get used for every practice, every race and every final I do for the next 2 years before I even think of replacing them. As far as I'm concerned if 1 set can be used and charged in 1 evening's club racing then there is no problem when nationals and regionals last all day.

I think I'm turning into Victor bloody Meldrew

Demon DL5000, can't see them anywhere. I'm looking at replacing them anyway, but don't want to be forced into it.

Following a little more research, the DL5000 is a LiPo with side exit wires. This would probably fail the BRCA rules depending on width. I believe this cell was only ever on the very first LiPo list which was for the trial Touring Car series a few years back. Of the cells on that list some (including the DL5000) didn't meet the final LiPo rules and were removed. You'll see at the bottom of the 2010 list is a section for those cells that were transferred from the "trial" list to the official EB listing.

I am no longer the Off-Road technical officer so can't 100% comment on this years list but I believe the above should give you an answer on the original question, so in theory they haven't been legal for a while.

2008 TC Lipo List is here (http://www.centralbooking.org/cbs/images/stories/brca/eblipo2008-12.pdf)

Following a little more research, the DL5000 is a LiPo with side exit wires. This would probably fail the BRCA rules depending on width.

Technical Rule 3.. --- Lithium Based Batteries – for 2010.
Lithium Based (LiPo/LiFe) Batteries can be approved, but must conform to the following :-
1. Lithium Based (LiPo/LiFe) battery packs must have a hard, protective case that completely envelopes the
cell(s). The case should be made from ABS or a similar material. The two halves of the case must be
factory sealed in a way that any attempt to open the case will destroy the case. The only opening in the
case that is allowed, is for the exit of wires.
The maximum case sizes are as follows: -
2S Batteries.
Length: 139.0mm.
Width: 47.0mm. (The max. width includes any side exit wires).
Height: 25.1mm. (Chassis location features additional to this dimension are allowed) Saddle-Pack cells are allowed, but must comply with the above dimensions. Saddle-Pack cells must have a combined dimension of 139.0mm max when placed end to end.

Exactly as I was saying. It's not the side exit wires that make it fail, more the width including those wires.

Looking at the 2008 TC list, the DL5000 measures 45.1mm wide not including wires. I can't see the wires measures less than 1.9mm can you, so that would be the reason for a fail and not being included in the offical EB listings for 2009 onwards.

Well they're due for replacement anyway, been running them just under two years now. The problem I've noticed with them (other people who have the same cells , but starting to see it in mine now), because the wires are bent back, you'll get breakages in the insulation. Now for the main power wires, you can get round this by using heatshrink and electrical tape if it's not too near the lipo case itself, but I've seen exposed wires on the balance leads, and they're pretty much nothing you can do to fix that. Think I'll get myself some gold 3600, don't need any more power than that anyway really.

Have two stick packs bought for my birthday, had trouble getting them and at one point was offered money back. Silly me, but looking on the bright side didn't get ride of my last years 4900 gold packs. :cry:

I had to sell off my DL5000's last year, before my regionals started. PW explained the reason why and obviously there could not be any exceptions. I feel the DL5000 are better packs than the LRP 5300 28c I purchased. Demon even showed examples of the packs performance after 400 charges, without balancing them (no loss in performance indicated).

Shame but rules are rules...

So does anyone actually have the reason why the TP darks are not on the list??

[sldmodels]

I like the Demons, although not as much punch as the Venom's I'd bought just a month earlier, which aren't BRCA legal either so I can only use them for practice or at clubs we're they're not so strict.

If it's a width issue, then surely they can either make them like the Trakpower gold lipos, or have the wires coming out from a different location. It would mean retooling the machine that makes the packs, but it's an option for them.
