Exploding Battery
I just got a new 4.8 Ni-Mi 2300 battery pack that exploded right after fast charging @1.5 amps,
I was was using a peak detection charger( Apex its rated for NIMI's) and the pack took 1400ma of charge, one of the cells exploded within 2 min. of of disconnecting ... never seen this happen before ... any one else ??

RE: Exploding Battery
Could have been a faulty cell or the battery was charged before charging again with a faulty charger. The only time I have seen them explode is if they are damaged or overcharged.
Cheers.

RE: Exploding Battery
Was this your initial charge that you were making at 1.5 amps.
If so, this may be your problem.
The intial charge needs to be at C/10 or 230ma or less with that pack.

RE: Exploding Battery
Agree - you need to slow charge on your first charge to balance the pack. I usually cycle my pak 3x after the first slow charge !

RE: Exploding Battery
sound like you fast charged it on a charger desighned only for NiCds. NiMh don't work right off the delta peak method. NiMh don't like to be fast charged for that matter. any your just asking for trouble doing it on the first charge. I've now seen 4 plane hit the dirt wanting to blame someone turing a radio on. I'd ask them how they charge their battery and they exculisivley say fast charging. Just can't do this. They weren't desighned for it. Use your overnight chargers
get something like this

RE: Exploding Battery
I would suspect the second pack.
Get two new packs or make sure that the second pack is the primary for a two pack installation.
