Shocking

[Chequered Flag Racing]

New in August last year (18/08/11, still have receipt) and probably had no more than 10 charges on them. Have some Intelect saddles with similar usage of the same age but no signs of damage. Non of my 1s cells have done this.

Have read stories of manufacturers increasing capacity but to keep the case within the regs they have to thin the battery case, hence some of the puffing we might be seeing with our LiPo's.

Got them out with a view to using them in a GT12.

Did you leave them fully charged when in storage? I read in one of the RC car mags this month that it can be dangerous leaving Lipo batteries fully charged. Apparently it's not such a high risk if you are using them regularly.

Nope

I have two sets of these, one half of one set has done that, the other hasn't.

Still using both sets, think the main reason is my jumping "style" (get airborne, try and keep the car level as it slaps the chassis off the ground).

Its been in use for 6 odd months since it split, appeared to just be shoddy gluing round the edges of the case. (or shoddy gluing in comparison with what i was doing with the car!) Have taped it shut, and its stayed pretty much the same since.

None of the hard cases, thick or thin would stop a lipo from swelling in any way...so I wouldn't worry about that! And in this case, I wonder if a thinner case would be more flexible and bend more, a thick one would be more likely to crack open like that as it can't give as much!

The case only really helps to prevent puncturing and make them look better.

Def not good though is it...feeling your pain for sure!

there was some fakes going around of those lipos

Bought from a well known model UK model shop so would have thought they'd be from Orion

What voltage are they now? If below 3v that's your problem. If not, back to Orion IMHO.

odd they have both done it, what ever happened they appear to have been connected when they failed

3.82v each when photos taken on Monday this week.

I could try Orion I suppose
