5A 3.2V PCB Protection Circuit Board for 18650 LiFePO4 LiFe Battery Pack Cell 1S

Description

Product features:
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.
Main function:
Over charging protection, over discharge protection, short circuit protection, over current protection function.
Technical parameter:
No.
