Why 14s 52v
52v is superior for 48v systems in many ways.
14s x 3.6v gives you 50.4v nominal voltage. (Perfect for 48v systems)
You can adjust the parameters via Bluetooth bms to stop charging at 80 or 90%. Charging lithium to 80% increases cycle life to near 2000 cycles compared to 500 cycles charging to 100%.
