HIGH-ACCURACY, HIGHLY DURABLE: High-accuracy voltage detection circuit, fine workmanship and durable, Effective life greater than 50000 hours. MULTIPLE PROTECTION: Over-discharge protection, overcurrent protection, overcharge protection, short circuit protection; A combination of 4 safety features that work together to provide ultimate protection for your devices, your chargers and most importantly:you. LOW STANDBY CURRENT: MOS transistor can control the battery charge and discharge, low standby current consumption. WIDELY APPLICATIONS: Use for variety of capacities and various shapes 3.7V lithium batteries,Massager battery pack, LED light backup power supply, solar street light battery pack, monitor standby power supply, etc. ATTENTION: Strictly according to the diagram wiring: B+: Battery V+ Positive, B-: Battery V- Negative, P+: Output / Charging V+, P-: Output / Charging V-, MB: The connection point between the batteries.Otherwise it will cause damage to the chip. Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. 2S 8A Li-ion Lithium Battery 7.4V 8.4V 18650 Charger Protection Board Module is a small PCB mounted Li-ion Lithium Battery charger protection module.
