Battery Protect | Victron | Smart BatteryProtect 12/24V-65A
Product Details
The Victron Smart BatteryProtect 12/24V-65A is an automatic low-voltage disconnect (LVD) device that protects your 12V or 24V battery from deep discharge. Rated at 65A continuous, it connects in series between the battery and your DC loads — fridges, lights, pumps, entertainment systems — automatically cutting power when battery voltage drops to a programmable threshold. When the battery recovers through solar charging or alternator input, loads reconnect automatically. Built-in Bluetooth Smart adds wireless configuration and monitoring via the VictronConnect app. A must-have for caravans, 4WDs, and marine applications where battery protection matters.
Key Features
- Built-in Bluetooth — configure and monitor via VictronConnect app (iOS & Android)

- Programmable disconnect and reconnect voltages
- 65A continuous rated / 250A peak (30s surge protection)
- Alarm output with 12-second pre-disconnect warning
- Remote on/off input for system integration
- 90-second delayed disconnect prevents nuisance trips on short voltage dips
- Solid-state MOSFET switching — no relays, ignition-proof, silent operation

How It Works
The 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.
Use Cases
In caravans and camper trailers, the BatteryProtect is most commonly used to protect the house battery from being flattened by the fridge, lighting, or 12V accessories while parked off-grid. At 65A rating, it handles the combined load of a compressor fridge, LED lighting, a water pump, and 12V entertainment with headroom to spare. When camp solar brings the battery back up overnight, everything reconnects automatically.
For 4WD touring and marine applications, the BatteryProtect is installed on the auxiliary battery to ensure that running loads — ARB fridges, winch power circuits, pumps — cannot flatten the battery to the point of a no-start. The 65A rating suits most dual-battery setups, and the IP67 electronics withstand the damp, vibration, and temperature extremes of these environments.
App Control — VictronConnect
The 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.
