Mainboard Protection Function:

• Overcharge protection
• Over discharge protection
• Overcurrent protection
• Module does not need battery protection board as it has inbuilt
• battery protection system.

Installation Introduction:

• 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. Press and hold the switch, flashlight LED light starts, then press and hold to turn it off
• 3. 2A output is not continuous current, it changes according to USB connecting load, automatic current output as per load
• 4. If battery is connected incorrectly, the reverse polarity will burn the circuit. So, make sure to check the battery polarity when connecting.

Special Instruction:

• 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
