the type of connector is a GX16 aviation plug. It has four pins ( male on battery and female from controller on e bike.
FWIW, if you stick with that kind of connector, I'd swap those, becuase having a connector with exposed male pins that could be shorted together on a battery is a Really Bad Idea. I'd always use a
The +and- are obvious but not sure about the other two wires in the plug. Wonder if you can buy an adapter. Any thoughts ?
You'd have to trace the wires from the plug to the inside of the battery and the charger and / or controller, to see where they go. They might not be hooked up, or they might be sensors, or even serial data wires. Depending on what they are, if they're not correct, it could just not function, or it could damage things in the battery or controller/etc.
Also note that as others have said, if the polarity wasn't correct on the main battery/controller connection to start with, there may be damage to either or both now, especially if the batteyr power wires were connected to what might be low-voltage data lines.
