How to use:
1 Connect 3.2V LiFePO4 battery
2 Connect DC 5V power supply to fully charge the battery
3 Connect load to discharge
 
Note :
1 There is no voltage output without battery
2 Please fully charge the battery before connecting the output load
3 When the charge/discharge current exceeds 50%, the module will heat up. Please increase the heat dissipation.
