Lithium Battery BMS / PCB / PCM
Li-ion cells should always be used with a protection circuit to prevent the cell from over charging or over dis-charging. Choosing the correct circuit and applying it appropriately is vital to the longevity your batteries and your own safety.CNBM test each Cells and BMS/PCB/PCM before manufacturing and promise it is functional and safe.
BMS / PCB / PCM is the "heart" of Lithium battery pack. BMS (Battery Management System) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and balancing it.
