This small board provides an easy way to protect rechargeable batteries from being completely drained if a device is accidentally left switched on. It can work with devices that run from a single battery, or two separate batteries. Both thresholds are fully adjustable, and it can handle several amps per battery, drawing just a few microamps when off.
