Tips: We can provide wholesale if you need large quantity, please contact us. Thanks.
 

 

Specification:

 


The protection board uses the Japanese Ricoh rechargeable lithium iron phosphate battery protection IC;
1) built in high precision voltage detection circuit;
2) the terminal of the charger is using high voltage device;
3) built in the 3 section over current detection circuit
(over current 1, over current 2, load short circuit);
4) through the MOS tube can control the battery charge and discharge;
5) low standby consumption current.
