Daly BMS gone crazy..Update Opinions
I was charging my 120ah lifepo4 battery yesterday and came in for lunch and saw it shut down..I figured it hit the 3.65 volt cell limit and shut down,I went out to check it and saw this on the Blueto...

Using the battery bms for shutdowns would be like using your emergency brakes instead of the regular brakes.
Agreed... What is your battery’s cut-off voltage??...Of the drop-ins that I shopped, the BMS cut off occurred at 14.6v, thus BMS may simply be looking out for your battery’s best interest - beyond what’s the occasional cell balancing, never leave the charger on the battery for an extended period of time...
From my perspective, theres no need to charge a LFP at 14.6v, and I wouldn’t recommend such a charger - mine charges perfectly and without incident at about 14.3v, including the naturally occurring dc voltage drop within the wiring length.
