happend to me 4 times. 3 of them from IB 4200 batteries leaking juice while charging or discharging. and 1 爆ed EP 4200 for a stick pack....very scary!!!!
no 先兆...but i would say usually the hottest battery within a pack is easier to 爆 while charging or discharging.....
really love the sanyo and GP in the old days....no such problem for me at all
WA SHI T .......VERY NASTY WOR , SO THIS SPECTACULAR EXPLOSION CAUSE BY HOW MANY BATTERY ??

I THINK WE NEED TO CHARGE THE BATTERY , COVER BY THE SAND BAG
