4S 4A-5A Lithium Battery Charger Protection Board BMS

Product Discription:

The main IC adopt the original “ricoh” import components. Have overcharge, discharge, over current, short circuit protected function, use as in a variety of capacity of 3.7 V lithium batteries. Adopt NSK protected IC, VISHAY, AOS, IR high quality MOSFET, FR – 4 plank, low temperature coefficient and excellent design, fine workmanship,complete testing. Small size, suitable for many occasions with high integration, low cost requirements, ensure the battery pack absolutely safe and reliable

Feature
– Built-in high precision voltage detection circuit.
– Connect to the charger terminals which using high pressure device.
– Built-in three over current detection circuit (1 over current, 2 over current ,load short circuit)
– Through the MOS tube ,it can control the battery charging and discharging;
– Low standby current consumption
