which ib4200's are the exploding ones?

[quincey]

i read somewhere a list of the ib4200 which were the duff ones,and now i can not find it.
ive sold a customer 3 packs of interllect 4200's and 2 sets are knackerd in 3 months,he's chargeing them on a pitbull x3 charger but says the charger sets its self and discharges them on a zero v board but takes them off before the lights go out.
any help would be greatly appreciated.

sure pitbull is user programable, what is he leaving in them while there stood?

lol, 2 threads above this I just clicked on, the sticky thread at the top of the electrics section.

Personally, I'd give that 0V board the major swerve becasue with any discharge tray unless you leave all the cells to finish you won't have balanced them, just discharged them all to a lower voltage, does that make sence? A better board would take each cell to say 0.9V and hold them there so if you have a duff cell this happens quickly and it stays at 0.9V while the better cells in the pack continue discharging.

Also there is risk in forgetting and leaving to go to 0V which I think it's generally agreed would be a bad thing.
