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.
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.
