Charging Tip When the power switch is turned ON, the battery boosts to 5V to power the Atom. When the power switch is turned OFF, the battery can be charged via the Atom USB interface. The boost and charging states need to be manually switched with the switch and cannot occur simultaneously.4-level battery display (red LED) for battery status, and charging status is displayed (blue LED: charging, green LED: fully charged).

Compatibility If used with the Atomic Echo Base, all pins on the right side of the Atomic Battery Base (5P) must be cut. If used with Atom Echo, the G33 pin connection must be cut. In these combinations, the Atomic Battery Base is only used for power supply and cannot read the battery voltage status.
