M5Stack ATOM TailBat – Battery Accessory for ATOM

Description

The M5Stack ATOM TailBat is an external battery accessory designed for ATOM. It plugs into the tail of an ATOM controller to provide direct battery power for mobile use scenarios.

The official product page lists a built-in 190mAh rechargeable lithium battery managed by the IP5303 power management chip. A front switch button controls the power, and a red LED indicator shows the power or charging status.

The usage method follows the M5Stack Core style: single-click to turn on power and double-click to turn off power. The indicator flashes during charging and stays on when fully charged. The built-in battery can only be charged through the USB Type-C interface, not through the GROVE interface.
