BPM-12 12V Intelligent Battery Protector

BPM-12 12V Intelligent Battery Protector Product Overview The BPM-12 is an intelligent electronic device mounted on batteries. It monitors battery power and charge-discharge status in real time. When the battery is nearly dead, it cuts off the connection promptly to reserve the minimum power for the next start-up and prevent over-discharging. Application Scope Vehicle battery protection RV dual-battery isolation protection Motorcycle battery protection Backup battery protection in computer rooms Technical Specifications Operating Voltage: 12V Standby Current: ≤ 1.5mA Continuous Current: 120A Instantaneous Current: 1200A Applicable Vehicles: Displacement ≤ 4.0 Remote Control: 320ft (2pcs) Key Features Non-contact switch control (dust/waterproof). Remote control support. OLED screen (displays voltage, power, on-off status). LED working status indicator. Power-saving design (400μA standby current, 180-day parking protection). 16-square pure copper flame-retardant cables (supports large start-up current). Thickened manual switch (easy installation). 120A self-locking controller (1200A short-term start-up current, zero standby power). Flexible installation (any input/output, positive/negative pole). IP68 protection (full sealing + EVA sealing). Military-grade components (built-in hardware watchdog). Fail-safe design (maintains normal operation even if chips fail). Usage Instructions Power on: Screen shows model/version, enters main interface after 2s. Main interface displays: Remaining capacity (e.g., 84%), real-time voltage (e.g., 12.63V), cut-off power setting (e.g., 50%), working mode ("Sm" = enhanced safety), device status (On/Off). OFF/- Button: Wakes screen; powers off (disconnects battery); subtracts values in setting mode. ON/+ Button: Wakes screen; powers on (connects battery); adds values in setting mode. Remote Controller: "OFF" = disconnect; "ON" = connect. LED Indicator: Red flash = disconnected (1s: manual/remote; 2s: auto-disconnect with sufficient power; 5s: low power); Green flash = connected (1s: sufficient power; rapid: low power countdown). Special Reminders A. Safe mode "OFF": Unconditional disconnection upon instruction.B. Safe mode "ON" (voltage >13.2V, engine running): No disconnection (manual/remote/auto) for safety. Setup Guide Enter setup: Hold "ON/+" for >2s, click "OFF/-" (see "SET MODE"), release. Protection Voltage (default 12.2V/53% capacity): Adjust with +/-; hold "ON/+" to next step. Disconnection Delay (default 300s): Adjust with +/-; hold "ON/+" to next step (delay stops if voltage >13.2V). Safe Mode (default "ON"): Adjust with +/-; hold "ON/+" to next step. Save Settings: Select "Yes/No" with +/-; restart. Note: Hold "OFF/-" to cancel settings anytime. Wiring Instructions Fix adapter one end to battery’s positive/negative terminal. Connect original vehicle’s positive/negative cable to adapter’s other end. Fix main unit’s two wires to adapter’s both ends. Connect main unit’s yellow wire to the battery’s other electrode.
