I'm having a battery built with a bluetooth BMS (this one) and would like to know if using it to limit high voltage to 4V per cell is a substitute for using a charger with a 80% or 90% cutoff.
My (uneducated) assumption is that the charging voltage output on a 58.8V charger set to charge at 90% would be around 56V, and that limiting to 4V per cell through the BMS, the voltage output would still be 58.8 but that somehow the current wouldn't be allowed to pass when each cell has reached 4V (or 56V for the whole pack).
Is that assumption valid and what is best for maxing out on the battery life time?
