Actually, the design of the batterypack is a funded project for Africa for use both as a mobile battery for e-scooters, and home use as energy storage because the power grid is very unreliable.
I do need to replace the FETs and coils for use of 48V 20Ah battery pack, but i also need to change software in the MCU to accomodate to the higher pack voltage. Has this been done before as you know off?
