Re: 38 mile commute

treefarmer, what is the voatage of your battery when your bms cuts out is one cell higher then the rest, last one in line on the pos. end # 16 cell group ? Maybe this is the funny cell ? And tripping the bms ? with it being fully charged.This is one that I have had the most problems with. Good luck....

Re: Signalab bms, need more amps.

I think ping told me to put solder on the shunts to raise the amp output. Ping also has a 60amp.BMS it's a lot bigger in size. Before you put solder on it let someone else back these up.
