With above hvd and lvd I ment in fact that i really cut-off high and low voltages with low voltage disconnect modules. A chargecontroller for solar charging and extra high voltage disconnect + low voltage disconnect module between the charger and battery pack as most chargecontroller do not cut-off but change to float mode. So when i really cut-off Im wondering then if i need a bms if set the setpoints accordingly.
If you are monitoring cell voltages and disconnecting when cells go out of range - you have a BMS.
