1s 3.7V 4A BMS Module For Li Ion Battery
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its safe operating area monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it.
- 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+: connected battery positive, B-: connect to battery negative, P+: connection charge / discharge positive, P- connection charge / discharge negative, Otherwise it will cause damage to the chip. After connection,it need to first charge activation, then will have the output.
With over charge, over discharge, over current, short circuit protection function, for a variety of different shapes of 3.7V capacity lithium batteries. Well-designed, comprehensive test. Compact size, suitable for many requirements of high integration, low cost occasions, can meet the performance requirements of many aspects, to ensure the absolute safety of the battery group.
