Battery PCB BMS PCM
Li-ion, Li-Poly and LiFePO4 battery packs should 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.
For high drain Lithium batteries, protection chip board is not a necessary for protecting the battery from over-charged if a good quality balance charger is being used on charging the battery. But it still needs attention not to over-discharged the battery without using the protection ship board.
High drain and high voltage LiFePO4 & Lithium battery packs with a battery BMS (battery management system) could avoid over-charged / over discharged, and also get balance monitoring from the system, with the balancing management, it will greatly keep good consistence and extend battery life, safe and secure the high discharge current enviorment.
The protection chip board can not be used on replacing batteries for digital camera, laptop or power tools. The electronic devices like digital camera, Laptop or power tool will only work with original chip boards.
