A friend of mine his Ebike is totally destroyed by a Lipo fire.
Full Suspension Bull Sugar Max Team XTR with 66,6v 10ah 18 fet controller Crystalyte HS Cycle analyst etc etc.
My friend was Bulk charging the 18s 2p Zippy's in his garage, after a while a neighboor rang the door bell that there was a huge amount of smoke getting out of the garage.
My friend opened the garage door and the rest you can see above.
Well, here is what I think what happened :
December 2011 the Ebike got his last charge, my friend installed a GPS tracker to track it down when if it ever got stolen, this GPS tracker got it's own battery with a few mAh and got his main power from the 18s2p pack by a DC-DC converter (72v->12v) After three months DEC-JAN-FEB, the GPS tracker sent a text message ( Battery low ) so friend is charging the bike without checking his cells. I'm sure that some cells did drop to a way way way too low voltage like 1v or 2v or less. Some cells were probably dead and the rest of the cells got way over the 4,20v per cell and caused a fire and later a complete meltdown.Luckily nobody got hurt, my friend could remove his car and by doing this he got a "black" long but he is fine now. If the neighboor did't drove by...............
Just want to share this with you people, don't get lazy, more and more people start to use RC Lipo's for their Ebike,incl me and some friends.
Just be careful out there !
