Is it even possible to connect LiFePo4 batteries in series if they have BMSs? I can see two issues. 1) When charging, will the battery that charges first go into high impedance and prevent the other batteries from charging? 2) When charging, will the battery that charges first go into high impedance and therefore the full voltage of the charger will be build across that battery and cause it to go into the overvoltage protection mode requiring a reset?
