Rated at 100A continuous, it sits in series between your battery bank and DC loads — protecting your battery from deep discharge by cutting load power the moment voltage drops to a programmable threshold. Once the battery recovers (via solar, mains charger, or alternator), the unit automatically reconnects. Built-in Bluetooth enables full configuration and monitoring via the VictronConnect app. Ideal for 48V off-grid solar systems, marine setups, and lithium battery installations.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBuilt-in Bluetooth — configure and monitor via VictronConnect app (iOS \u0026amp; Android)\u003c\/li\u003e\n  \u003cli\u003eAutomatic low-voltage disconnect — protects battery from over-discharge\u003c\/li\u003e\n  \u003cli\u003eProgrammable disconnect and reconnect voltages\u003c\/li\u003e\n  \u003cli\u003e100A continuous rated \/ 250A peak\u003c\/li\u003e\n  \u003cli\u003eAlarm output with 12-second pre-disconnect warning\u003c\/li\u003e\n  \u003cli\u003eRemote on\/off input for system integration\u003c\/li\u003e\n  \u003cli\u003e90-second delayed disconnect prevents nuisance trips on short voltage dips\u003c\/li\u003e\n  \u003cli\u003eSolid-state MOSFET switching — no relays, ignition-proof, silent operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMax Continuous Current\u003c\/td\u003e\n\u003ctd\u003e100A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePeak Current (30s)\u003c\/td\u003e\n\u003ctd\u003e250A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSystem Voltage\u003c\/td\u003e\n\u003ctd\u003e48V\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e24-70V\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eDisconnect Voltage Range\u003c\/td\u003e\n\u003ctd\u003eProgrammable 40–58V\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eReconnect Voltage Range\u003c\/td\u003e\n\u003ctd\u003eProgrammable 44–62V\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSelf-consumption\u003c\/td\u003e\n\u003ctd\u003e1.9 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBluetooth\u003c\/td\u003e\n\u003ctd\u003eBuilt-in Bluetooth\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eIP Rating (Electronics)\u003c\/td\u003e\n\u003ctd\u003eIP67 (fully potted)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eDimensions (L x W x H)\u003c\/td\u003e\n\u003ctd\u003e62 x 123 x 120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eThe BatteryProtect installs in series between the battery and your DC loads — important: it protects loads only, never in the charge circuit or starter motor line. When battery voltage falls to the set disconnect threshold, the alarm output activates for 12 seconds as a warning before loads are cut after a 90-second delay. This delay prevents false trips from short-duration voltage sags under heavy starting loads. Once the charger (solar, alternator, or mains) raises the battery voltage back above the reconnect threshold, loads are automatically restored after a 30-second delay. MOSFET solid-state switching means no audible relay click, no arcing, and the unit is ignition-proof — suitable for fuel-present environments.\u003c\/p\u003e\n\n\u003ch3\u003eUse Cases\u003c\/h3\u003e\n\u003cp\u003eIn 48V off-grid solar systems, the BatteryProtect ensures your inverter, lighting, and DC loads cannot flatten the battery bank overnight. When solar generation resumes at dawn and the bank voltage recovers, all loads reconnect automatically — no manual intervention required. Pairs well with Victron MPPT chargers and GX monitors.\u003c\/p\u003e\n\u003cp\u003eOn 48V marine and commercial vessels, the BatteryProtect provides a reliable last line of defence for the house battery bank. Critical navigation equipment, bilge pumps, and communications remain protected from accidental deep discharge even when the vessel is unattended at anchor.\u003c\/p\u003e\n\n\u003ch3\u003eApp Control — VictronConnect\u003c\/h3\u003e\n\u003cp\u003eThe BatteryProtect Smart includes built-in Bluetooth Low Energy (BLE) for configuration and monitoring via the VictronConnect app (free, iOS and Android). Adjust disconnect and reconnect voltage thresholds, enable or disable the alarm output, view real-time battery voltage and unit status — all wirelessly from your phone. The Instant Readout feature lets you check live data without needing to pair the device. Bluetooth can also be disabled permanently for permanently installed systems where wireless access is not required.\u003c\/p\u003e\n\u003ch3\u003eWhy Buy From Revolution Power\u003c\/h3\u003e\n\u003cp\u003eRevolution Power is a Queensland-based Victron Energy specialist supplying caravanners, boaties, and off-grid installers across Australia.
