Would the controller be able to handle 14S li-ion (3.6V/cell nominal)? I have a line on a 14S li-ion battery pack with full BMS at over 200Wh/kg with 1000 cycle life.
The controller is designed to be able to handle up to 60v. The frame mounted PCB has a voltage divider circuit that brings 60v down to 5v etc which is read by the controller and used to calculate the pack voltage.
