Walfront Lithium Battery Protection Board LiFePO4 Battery Pack Balancing Battery Protection Board Piece Set B 12V 100A 4 Series BMS Protection Board

【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer. [Explosion Prevention] As the core of the battery pack, the lithium battery protection plate is an important component to ensure the safety of the battery pack and prevent explosion, fire and damage. [Multiple protection functions] Through the lithium battery protection board, the battery pack can effectively avoid overcharging, overdischarging, overcurrent, short circuit, etc., ensuring the stability and safety of the battery pack. 【Balance Function】This protection board has a balance function, which ensures that each cell is in a balanced state, extending the service life of the pack and ensuring the performance and stability of the pack. [For 4 strings of 12V lithium iron phosphate batteries] This protection board is suitable for 4 strings of 12V lithium iron phosphate batteries, and is equipped with 5P-250mm wire, which can meet the battery pack connection and use conditions. Masu. [Extend lifespan] Selecting the appropriate protection plate and using it rationally is very important for the service life of the pack, and in order to ensure the stable operation of the pack and extend the service life, the protection It is necessary to pay sufficient attention to countermeasures. This product is a protection BMS board designed for 4 series 12V LiFePO4. The board also has multiple protection functions such as overcharge protection, overdischarge protection, overcurrent protection, and short circuit protection, making it safe to use. Additionally, the board's built-in balance feature allows each cell to be fully charged at the same time.
