LRP VTEC LiPo 5100 saddle pack

jimmy · #1 20-10-2008

LRP sent us news of their new saddle pack lipo. Along with the huge capcity and high discharge rate, the lipo also features a low profile to fit most cars. LRP say 'ALL' saddle-formation off road cars are a direct fit - though the pre-wired link wire could be a little short in some cases from the looks of it.

LRP continues to expand its Competition Car Line LiPo packs with this new 28C 5100 saddle pack. Developed for extreme power delivery and runtime. Just charge and drive. Now anyone can enjoy the easy use and performance benefits of this new technology. This pack is specially designed to perfectly fit r/c models with a 6-cell saddle pack chassis design. More and more countries are allowing LiPo batteries for racing and LRP is able to offer the perfect LiPo battery for every racing class. This saddle pack fits every 1/10 pan car as well as every 1/10 electric Off-Road car using this battery.

I was thinking that too.

Doens't look like it from the photo, but another angle might say different.

That'll be for discusion by the Electric Board (probably at AGM time). I would have thought it will be left at 5000mAh, as it's down to the construction of the cell and Lithium content (my understanding anyway)

No doubt we'll hear more after this weekend.

there is no 'industry standard' high amp power connectors, the Taimya connectors act as 2 functions

- stop the wires shorting out in the packet
- allow Jonny RTR to use the cells straight out of the packet

Actually, looking at the photo again, it does look like the case might be the same transparent blue plastic as the 5300mAh stick pack.

The wording made me think they were heat shrinked not hard cased but I could be wrong (and probably am)
What's the idea of the capacity limit? At the weekend I was taking about 1000mah out of the cells in a run in 4WD with the Trakpower 3200mah saddles. Obviously this would be more outdoors on a bigger track with more grip - but surely no one would ever use 5000mah in off road?

I thought it was something to do with snakes on a plane... on no, hold on, sorry, something about the amount of Lithium per 'cell' thats allowed on a plane... at least thats what I thought I heard...

looks like heat shrink to me, if you go the the lrp web site and look at the images you can see the edge of the heatshrink

Bungleaio · #10 20-10-2008

The track power ones are heat shrunk too but have the hard case underneath

bigred5765 · #11 20-10-2008

ahh right ok

Not sure about that. Im pretty certain the TP cells are hard cased externally. The Maxamps ones I think that may be the case though.

i think it has something t do with mah and c rating the higher the mah the lower the c rating can be to get the same max or adv amp so a higher mah and higher c rating the better thats my understanding of it.

I have managed to get the 3200mah trackpowers pretty hot on a high grip track using a 4.5 and almost dump them

. I think around 4000mah capacity or a higher C rating would be good, and pretty much cover any motor / driver in a 5 minute race.

Lowie · #16 20-10-2008

should these fit in a Pred?

I've seen you drive so I can believe it

I'd do 2 races on the same pack and still have power to drive home.

I've raced the 3200mah stick back to back against the 4900mah trakpowers and the C rating certainly makes a difference - I prefer the lower C rating

OldTimer · #18 20-10-2008

If these lrp lipos have no lugs on the bottom then they are illegal according to the proposed efra rules for lipos (max height 23.5mm, 25mm if location protrusions are included). These are 25mm and i guess with a flat bottom, also rules out the 4800mah trackpower saddles as well

as they are 30mm high.

Also the 3200 trakpower would be illegal as they are to long

if we were racing to efra rules of course.

Higher C rating is better jimmy

bigred5765 · #19 20-10-2008

and i think would look sweet in our x5, cant wait

J, Did that happen to be at Belgium you did that? - I remember youre car tonning a fair bit round the track! then drop to a slow for no apparent reason late on into the race when the English was stood waching near were you was pitting?
