8S-21S 24V 100A Smart BMS Battery Protection Board for LifePO4 Lithium Battery Pack with Balance Equalizer UART/RS485/CAN Communication Function Bluetooth APP Control
- 【High Integration & Precision Monitoring】This lifepo4 BMS adopts highly integrated design to realize ultra-high precision real-time monitoring. It can automatically identify the number of battery strings, flexibly support 8 to 21 strings configuration, maximum continuous current up to 100A, peak current up to 300A, tailored for LiFePO4. This protection board is very suitable for outdoor energy storage equipment, AGV intelligent vehicles, tourist buses, electric vehicles and low-speed vehicles and other high-current application scenarios.
- 【Multiple Protection Function】Our 8S-21S BMS not only has the basic protection of overcharge, overdischarge, overcurrent and short circuit, but also integrates the functions of balanced protection, and temperature protection. In addition, it is also equipped with a charging dual protection mechanism, in the case of overcharging the protection board and charger disconnect the input at the same time, eliminating the protection board battery pack overcharging hidden danger.
- 【Ultra High TVS Portection】The lithium battery protection board adopts the new TOLL wrapping technology, which effectively reduces the internal resistance and ensures high efficiency overcurrent. Built-in 5000W ultra-high-power TVS can easily cope with high-current impact, providing a solid protective barrier for the battery.
- 【Efficient Thermal Management】The BMS PCB protection board adopts CPU-level thermal conductive silicone grease, whose good thermal conductivity ensures that the heat is quickly transferred to the cooling system, enhancing the efficiency of thermal management.
- 【Good Heat Dissipation】At the same time, the battery protection board adopts an innovative design to effectively isolate the main board from the power board, which significantly reduces heat transfer, lowers the system temperature rise, and extends the service life of the battery. The unique water wave honeycomb structure of the heat sink is not only attractive, but also achieves rapid cooling through the optimized airflow channels, which ensures stable battery temperature even under extreme conditions and ensures the safe and efficient operation of the system.
- 【Simplified Operation & Enhanced Communication】The innovative same port design allows charging and discharging to share the same interface, which greatly simplifies the operation process and reduces the complexity of cables and interfaces. In addition,the BMS feature CAN, RS485, UART communication interfaces, support simultaneous multi-channel communication and rich expansion applications.Can be connected to Bluetooth, PC Software, GPS, Heating modules and other accessories.(Modules / Accessories Not Included )
