And therefore, you get the smallest one possible. Along with thaT size of discharge allowed, is a commensurate smallness of its ability to passively turn excess charge into heat. Can anyone tell me how much charge will not overun the bms’ ability to sluff off charge faster than the final stage of lion charging? My fear is that a certain butchness of charger will continue to add more charge than the bms can sluff. I have heard that a passive bms will continue to sluff off charge after the charger is detached.
IS IT SAFE, to continue to charge for a day or more, to top off and balance a pack, when you have a wimpy puny bypassed bms in your ride?
Passive balancing BMS reject anything over 4.2 volt per. Till balanced. By turning it to heat. The ability to do this is increased, as the BMS discharge rating is higher. I have a DALY 15 a bms, and was interested in if it is capable of dealing with a three amp charger, or more. When I built my board, I opted for the 30 amp DALY, for this fear.
