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.

Over charging protection, over discharge protection, short circuit protection, over current protection function.

4 string LiFe iron lithium-ion LiFePO4 phosphate rechargeable battery pack.
