If the battery capacity is greater than 5000mAH, the R5 resistor needs to be changed to 12.4K, while the one on the board is 6.2K (the factory setting is 4 strings of 16.8V, 5000mAH)

Continuous operating current: 18A Overcharge voltage: 4.235V+0.025V
Instantaneous current: 30A, overcharge release voltage: 4.19+0.05V
Charging voltage: 16.8-17V Overdischarge voltage: 2.8+0.08V
Charging current: 1-10A, over discharge release voltage: 3.0 ± 0.1V
Balanced starting voltage: 4.19+0.05V

The bidirectional C port of the product can only be connected to unidirectional electrical appliances or chargers, such as charging heads, mobile phones, and other electrical appliances. Prohibiting bidirectional C-port links to modules with bidirectional C-ports may result in frequent switching between modules that cannot be recognized, and serious damage may occur.Pay attention to one issue, any charging and discharging module, if you use the power supply as a battery, can only test the output and cannot charge the module. There is a risk of backflow

 Note:After plugging in the battery, it needs to be charged and activated before it can be used normally; Cannot directly connect the C port to the C port, it needs to be matched

USB charger tester is required to charge the phone, connect the tester https://item.taobao.com/item.htm?spm=a21dvs.23580594.0.0.1d293d0dz709ID&ft=t&id=784269991311&skuId=5358007097750
