Trakpower 4900 failure
 

One of my Trakpower 4900 is on the verge of massive failure as one of the cells seems to be failing following my last race meeting. The back of the pack has separated with expansion and when I have checked the cells they are now out of balance.

I am not going to try and charge them up as I don't think the wife woudl like me to burn the house down with a lipo explosion.

Any ideas on what to do with them as I only purchased them at the end of last year and I would have thought they would have lasted a bit longer due to me being very careful not to let them go too fall and alway balance charge them.

Any suggestions?

Anyone else with any ideas?

contact the store you got them from, they should then return them to Energon for you, or send them direct to Energon, with proof of purchase for the attention of warranty

Are you sure they are dissolved? I was talking to them a few days ago to arrange return of a faulty pack.

They were bought out I believe. If you can still get support I would appreciate the contact info.

Remember that you not only have to balance charge Lipo packs but if you want to have them last then always store them with around 60% charge left in them otherwise they loose capacity very fast.

tonym,

Before you make inncorrect statements try reading here, www.energonsolutions.co.uk.

Make me laugh, you post that then want help!!
Your first port of call is the shop you bought them from as i have already said.

So what was incorrect with my statement? Possibly the middle bit about potential for recompense? If others are still getting them exchanged by Energon Solutions I stand very much corrected. But I am right that the company no longer exists and I am right that I bought 4 Dark Series to find they are not BRCA approved – entirely my fault, but still doesn’t increase my love for TrakPower - hence the vitriol. Enjoy your day.

"Just bin them. I had two out of three Gold TrakPower 4900's do this - balance charged every time. The company is dissolved, so the potential for recompense is minimal. The sad thing is I then went on to buy TrakPower Dark series - dumb S**t."

Your incorrect as trakpower have never been a company, its allways been a brand, the guys that ran the company that sold/owned the brands split and energone was born,
There was never a company called trakpower to disolve (as you put it)

bit off topic but..
 

On the above - my UDC30 has both a lipo balance and a lipo fast charge function. Given that lipos should always be balance charged, would i ever fast charge without balancing? Why the extra function then?

On storage, how long is classed as "storage" and how long is "between use"?

All very confusing and when I try and go to their old site TrakPower.com there is a warning message saying the website has been hijacked!! All very sniffy.

So, we can blame Energone for not obtaining BRCA approval?

tony are you trying to be thick, or does it come naturally?

Ever heard of adverts, go to trakpower.com ans click find out more, bottom left, low and behold there is a dark serries advert, now you wont believe this but that was there before the company changed as thier launch of the dark serries

Id blame your self, you summed it up in your own post..... Where was it claimed they would be legal? Or were u a dumb s**t and assumed they would be (as you put it!!)

I am under the understanding a Lipo does not 'always' need to be balance charged.
if a lipo is to be left without use for more than a month (this would warrent storage mode) then use the storage function on your UDC30, which will charge each cell to 3.75 V (im pretty sure its that figure) if you are storing a lipo check its voltage 'per cell' every month or so as it will discharge slightly

Yep spot on - being thick does come naturally to me. Bought three gold, two went duff and then I order four Dark Series. How thick can you get.

Without thick customers like me there would be much less business. Oh, you are connected to the business arent you?

I'll probably go on to make similar mistakes and buy poor quality gear again - never learn hey.

Sponsored by them yes, work for them no....

It it true if you store packs for too long, they can be damaged though to the other posts.

sponsored yes, work for no, so you decide.


To the other posts
It has been proven that leaving packs full for storage can cause damage to them.

thanks
 

Thanks for that

Hi Jenski,

We have tried fixing a few packs like this but they have never worked.
Its best to put the pack in Water with salt added.
This will neutralise the pack so you can discard in your household rubbish.

Some people say you can recycle old lipos but i have yet to find a rycling centre that manages Lipos. Lead acid yes but not lipo.
