The Thunderstruck PFC-II 2500 is a versatile CAN controlled Charger that has user adjustable settings with the use of a EVCC (EV charge controller) or similar such as the Dilithium MCU. This way if you change your battery pack configuration you do not need to buy a new charger or pay someone to reprogram it for you.
This is the charger only. You will still need to order an EVCC or BMS MCU to set the charger up correctly.
