3S 20A Lithium Battery 18650 Charger PCB BMS Protection Board 12.6V 18650 Li Ion Battery Cell Charging Module 11.1V 12V 12.6V

3S 20A Lithium Battery 18650 Charger PCB BMS Protection Board 12.6V 18650 Li-ion Battery Cell Charging Module 11.1V 12V 12.6V


 


Specification:


 


1. 3 series 12.6V 20A lithium battery protection board (with recovery function -AUTO Recovery)


Application: lithium batteries with a nominal voltage of 3.6V, 3.7V (including 18650, 26650, polymer lithium batteries)


 


2. Product size: 59 * 20 * 3.4mm


 


3. Charging voltage: 12.6V-13.0V


 


4. Continuous discharge current (upper limit): 20A (if the heat dissipation envment is not good, please reduce the load current)


 


5. Continuous charging current (upper limit): 10A



 


Note : more than 3A current discharge products  rate is more than 3C  Ratio calculation formula : 1C rate of the battery , 2000 capacity is  equal to 2AH 1 2A maximum working current . 3C ratio battery , 2000 capacity is equal to 2AH * 3 = 6A maximum  working current . In use battery heats is ratio is not applicable to , this kind of situatic  can't use for a long time , the battery will soon be damaged



Note : don't put the good cells and in bad ! Three groups of battery  capacity / internal resistance as close as possible ! ( 2 + 1 good battery ,  the use effect of poor battery = the use effect of three bad battery )
