HIGH-ACCURACY, HIGHLY DURABLE: High-accuracy voltage detection circuit, fine workmanship and durable, Effective life greater than 50000 hours.
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.
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.
MOS transistor can control the battery charge and discharge, low standby current consumption.
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.
