Battery Not Charging – MBoards

Diagnosing Battery Charging Issue

Visually inspect battery. Check for swelling, burn marks, physical damage, torn shrink wrap.
Using a MultiMeter, check the voltage of your battery. Double check to be sure that your battery isn't already fully charged. The proper fully charged battery voltage is listed below:
- 6s Battery: 25.2v
- 10s Battery: 42v
- 12s Battery: 50.4
Using a MultiMeter, check the voltage of your battery. Be sure your battery hasn't been over discharged. The absolute minimum battery voltage is listed below (3v per cell shown. 3.2v recommended):
- 6s Battery: 18v
- 10s Battery: 30V
- 12s Battery: 36v
Many times the charger is the issue. Try the following with your charger:
- Check to be sure the AC cable is connected to the power brick properly.
- While disconnected from battery plug charger into wall, status light should light up green.
  - If status light does not turn on, test with a new outlet.
  - If status light still does not turn on, the issue pertains to the charger.
- Plug charger into battery, status light should light up red if battery isn't fully charged.
- Using a MultiMeter, test the output voltage of your charger. The output voltage must match the listed voltage on the back of the power brick.
If charger passes all inspections there may be an internal issue with battery pack. Contact us at support@mboards.co.
