Features

1. Power input (output): 28VDC

2. Battery capacity: 76Wh (3Ah)

3. Application: M28 series electric tools

4. Battery packs in a group: 7 packs

5. Basics:

This battery group is made of a control board and lithium batteries. The control board protects the batteries. It does so by monitoring the voltage, current and temperature to control the MOSFET. For example, the controller can prevent over charging, over discharging, discharging with high current and overheating.

The LED lights indicate the battery power. The battery is full when all (four) lights are on.
