My neighbour borrowed one of my 'in progress' bikes while i was away, before it was finished, rideable but not finished, no LVC set and nothing calibrated.
I got a msg saying the bike is dead and wont ride anymore, i asked what voltage the CA says and he said 40v... it was a 96v pack
The cells that recovered at all were sitting around 2v and i threw out the ones that didnt bounce back at all and tried to gently balance those higher packs up over a few days, and half of them held charge and seemed ok, they even did 3-5 cycles no problems... until this
This is definitely NOT the batteries fault, but a great lesson as to why not to try 'recover' undercharged and abused cells
