Hello and sorry to start yet another BMS thread.
I have 30 EVpower cell modules that I was about to install on TS lfp260ah cells. Recently EVDL list bot reported some failures of these boards, possibly to incorrect install.
Can others report in with success/failure stories for this system? I believe BMS is a good thing, but NOT if it is more likely to cause cell death than running free.
I have an Elcon charger that should protect the pack from excessive high voltage even if the shunts and bms charger control switch fail. (at least I hope so)
However, a shunt failing open and draining a cell is a BIG CONCERN since these are $300 cells and replacements might be impossible to find.

Also worth noting is this car will be used by someone who does NOT want to constantly check cell voltages, so I need some kind of fail safe system which is why I chose the cell modules in the first place.
Please advise.
Thanks
p.s. am I heading down the slippery slope to bottom balancing and no bms? argh! ~< :|
