Installation Introduction:

• 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
• 2A output is not continuous current, it changes according to USB connecting load, automatic current output as per load
• 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

Notes:

• The positive pole of the battery is connected to B+ and the negative pole is connected to B-, do not reverse it. If it is reversed, it will burn out!
• There might be some deviation due to manual measurement.
