Rotoye Batmon is a kit for adding smart battery functionality to off-the-shelf Lithium-Ion and LiPo batteries. It can be purchased as a standalone unit or as part of a factory-assembled smart-battery.

INFO

At time of writing you can only use Batmon by building a custom branch of PX4. Support in the codeline is pending PR approval.

Configure Parameters

In QGroundControl:

   • SENS_EN_BAT to true,
