BMS JBD 4S100A without Bluetooth, LiFePO4

JBD BMS 4S 12V (50A–150A): Total safety and maximum performance for your LiFePO4 batteries

Are you building your own 12V solar storage system, a backup power supply for your motorhome, or converting old lead-acid batteries to modern lithium technology? Don’t leave the safety and lifespan of your expensive battery cells to chance. The JBD (Jiabaida) CP04S024 BMS module monitors every detail without compromise – from the voltage of individual cells to extreme temperatures – so you can enjoy stable power without any worries.

Product Benefits: - Reliable continuous output up to ?150A: Its generously rated current capacity, combined with ultra-low internal resistance, can power even demanding loads and handle high current peaks.
- Integrated passive balancing: Automatically equalises voltage differences between individual cells during charging (from 3.525 V), which significantly extends the overall service life of the entire battery.
- Comprehensive multi-level protection: Immediate response to overcharge, undercharge, overcurrent in both directions and short circuits, thereby protecting your system from permanent damage or fire.
- Two-stage thermal protection: Includes 1× built-in temperature sensor for controlling FET transistors and 1× external NTC probe connected directly to the battery cells (protection against both freezing and overheating).
- Intelligent wire break detection: The ‘drop line protection’ function immediately disconnects the system if any balance wire becomes corroded, loose or broken. Product features:

- A compact solution for demanding solar and mobile applications The JBD CP04S024 protection hardware module has been designed with maximum reliability in mind for applications such as small solar power stations, uninterruptible power supplies (UPS), street lighting or the transition from 12V lead-acid batteries to LiFePO4 batteries. Thanks to a shared port for both charging and discharging (shared negative bus), the wiring is straightforward and clear. The module features exceptionally low standby power consumption, which prevents unwanted battery discharge during long-term storage. - Top-of-the-range hardware without unnecessary complexity
If you are looking for a robust and maintenance-free solution that does not require constant configuration via an app, this purely hardware-controlled BMS module is the ideal choice. The circuit board, used by leading battery storage manufacturers, features high-quality TOLL MOSFET transistors and solid M5 terminals for reliable screw-on connection of power cables. The package includes a complete set of balancing cables with a HY2.0-5P connector and an external temperature sensor. Technical specifications: - Chemistry: LiFePO4 (4S)
