  Installation instructions:
  

  1. First connect all your batteries (maximum 4 nos.) in parallel to make a battery pack.
     
  2. Then connect a thick copper wire from -ve of battery pack to B-
     
  3. Now connect a thick copper wire from +ve of battery pack to B+
     *** DO NOT CONNECT IN REVERSE POLARITY ***
  4. Connecting the batteries in reverse will burn the board.
  5. Put an insulation between the battery pack & this module to avoid any short circuit. Package includes:
     Mobile Power Bank 18650 Battery Charger PCB.

CONNECTION : It is possible to connect only one lithium battery or multiple lithium batteries in parallel. The capacity of connected battery should not exceed 10000 mAh, As long as the battery with a voltage of 3.5-4.2V is used.
TERMINAL indication of this power bank pcb board: B+ is for battery positive terminal B- is for battery negative terminal. Input voltage:5V 1A or 5V 2A Note: 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 damage the circuit.
