Dual Battery Connector
This connector will allow you to link two batteries together.
In doing so, you wont have to worry about switching between batteries when one has run out of power.
With both batteries linked together you can charge them at the same time via the controller.
*DISCLAIMER* Before linking both batteries together its recommended they are at equal levels of charge. Therefore we suggest draining both batteries independently, then you can link them together and charge as one via the joystick controller port.
