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