BMS JBD 4S200A without Bluetooth, LiFePO4

3S–4S 200A Protective BMS Module: Hassle-free protection for your LiFePO4 and Li-ion batteries

Are you building your own solar storage system, converting a caravan, or replacing an old lead-acid battery with a modern lithium battery? Without reliable management, even a minor error can destroy expensive battery cells. This no-compromise hardware BMS module with a continuous current rating of 200 A takes full control of your battery’s safety, so you can enjoy your energy with complete peace of mind.

Product benefits: - Safe continuous current of up to 200 A: It handles high current loads smoothly during both charging and discharging without the risk of overheating.
- Low-temperature protection: The standard integrated protection prevents dangerous charging of cells below freezing point, thereby significantly extending their service life.
- Integrated passive balancer: Keeps the voltage of individual cells in balance (balancing current up to 250 mA) for maximum usable capacity of the entire battery pack.
- Two-stage current protection: Reacts instantly to short circuits and overcurrent, thereby protecting your electrical installation from damage.
- Universal compatibility (3S / 4S): Suitable for a wide range of lithium chemistries (LiFePO4 and Li-ion / NMC).
- Maintenance-free hardware operation: The Bluetooth-free version ensures maximum reliability without the need to pair with an app or the risk of signal dropouts. Product Description: - A reliable controller for your 12V battery pack: The JBD hardware control module (ZP04S016) is the ideal ‘brain’ for small energy storage stations, solar systems, street lighting or converting 12V lead-acid batteries to lithium technology. Its robust design, featuring a built-in aluminium heat sink, dissipates heat from the power MOSFET transistors and ensures stable operation even in demanding environments.
- Intelligent protection in all weather conditions: Charging lithium batteries in freezing conditions is a sure-fire way to permanently damage them. This BMS module is therefore equipped as standard with a low-temperature charge protection function. As soon as the temperature drops below a critical threshold, the module safely interrupts the charging circuit. Connectors are also available for connecting an external temperature sensor (NTC) or optional heating foils for the cold winter months.
- Long service life thanks to precise balancing: The module constantly monitors the voltage of each individual cell. If the voltages begin to diverge, pulse balancing is triggered to gently equalise the energy. With its low self-discharge rate, it ensures that your battery does not lose energy when you are not using it. Technical specifications: - Model: JBD-ZP04S016
