When charging, battery level 0-25% one light is on,other lights off;
25%–50%,the second light flashes,the first light is continously 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:
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
