I think I figured out what those 2 wires are for thanks to seeing a CAN-Bus marking on the battery. They should be the CAN-Bus High and Can-Bus Low wires for communication. Which may screw my plan to transfer the charging connector to the new charger, it may still work but most CAN Bus systems will prevent charging if it can't communicate with the charger. Searching for a CAN-Bus 52v ebike charger is driving me crazy because I can't seem to find anything and google is spitting out garbage smart/intelligent chargers that are not actual CAN systems.
