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.
