- When charging, battery level 0-25% one light is on, other lights off;
- 25%–50%,the second light flashes, the first light is continuously on;
- 50%– 75%,the third light flashes, front two lights are continuously on;
- 75%—100%;the fourth light flashes, front three lights are continuously on.
- And four lights are on charging to 100%.
Mainboard Protection Function:
- Overcharge protection
- Over discharge protection
- Overcurrent protection
- Module does not need battery protection board as it has inbuilt battery protection system.
- 1.Circuit board B- connects power negative, B+ connects positive. Don’t inversely connect, it will result in burning of board. Make sure there is insulation between power and circuit when install the battery
- 2. 2A output is not continuous current, it changes according to USB connecting load, automatic current output as per load
- 3. If battery is connected incorrectly, the reverse polarity will burn the circuit. So, make sure to check the battery polarity when connecting.
- When connecting the board for the first time, connect the battery and then connect the micro USB charger and charge the battery to full capacity before using.
- It is required to prime the IC, so that it starts and shuts down accurately
