BMS JBD 4S100A Bluetooth-tal és LiFePO4

Smart BMS JBD 3S–4S LiFePO4 (100A): Maximum safety and full control over your battery via Bluetooth. Are you building your own 12V LiFePO4 battery for a motorhome, holiday home or solar system, and want to be sure that your investment remains safe under all conditions? You no longer need to guess at your battery’s status or worry about undercharging or overcharging individual cells. The JBD-DP04S007 smart protection module, in its powerful 100A version, puts continuous monitoring of every cell right at your fingertips via your phone’s display.. Product benefits:. - Real-time overview in the mobile app: Use the integrated Bluetooth module to monitor cell voltage, current, temperature and the exact state of charge (SOC) conveniently on your smartphone’s screen. - Rated for power consumption up to 1,200 W: A continuous discharge and charge current of 100 A provides sufficient headroom to power voltage converters, fridges and other common consumer electronics.. - Active cell lifespan management: Passive balancing (150–250 mA) automatically evens out minor voltage differences between cells during charging, thereby preventing premature wear.. - Comprehensive real-time protection: The control chip continuously monitors the system against overcharging, deep discharge, current overload, short circuits and critical temperatures.. - Detailed configuration via PC: Thanks to the optional UART interface, you can easily adjust voltage limits and the precise behaviour of the protection features using computer software.. Product description:. - Intelligent architecture for reliable power. The JBD-DP04S007 protection module is based on a tried-and-tested combination of a precision analogue sense chip and a powerful microprocessor. Rather than relying solely on analogue circuits, it evaluates the battery status digitally and with high precision. Thanks to its low internal resistance (only up to 10 m?), the board does not overheat unnecessarily and ensures minimal energy loss even during continuous current draw at the 100 A limit.. - Practical features for everyday use. The unit utilises a Common Port configuration, which significantly simplifies the connection of both chargers and loads to a single negative terminal (C-). The unit comes equipped with an external NTC temperature sensor for the cells and the option to connect a mechanical switch (Weak Switch), which can put the entire system into an energy-saving sleep mode with a current consumption of less than 800 µA.. - Optional battery care in winter. Do you operate the battery in conditions where temperatures drop below zero? The BMS supports the connection of an optional heating module (heating film). If the sensor detects frost, the module directs energy from the charger primarily towards heating; only once a safe temperature has been reached does it begin charging the cells, which would otherwise be irreversibly damaged in the cold.. Technical specifications:. - Model: JBD-DP04S007 V1.7 (100A version). - Supported chemistry: LiFePO4 (Lithium Iron Phosphate). - Number of cells in series: 3S to 4S (nominal voltage 9.6 V – 12.8 V). - Connection type: Common port for both charging and discharging. - Continuous discharge / charge current: 100 A. - Overcurrent protection: 110 A ±5 A. - Balancing current: 150 – 250 mA. - Balancing type: Passive. - Bluetooth: YES. - Internal circuit resistance: 10 mOhm. - Integrated communication: Bluetooth (on-board module), UART (non-isolated). - Temperature protection: 1× external NTC sensor + internal FET sensor. - Operating temperature range: Discharging: -20 °C to +75 °C | Charging: -10 °C to +65 °C. - Board dimensions: 160 × 105 × 10 mm.
