The 2 Victron battery monitoring solutions — what's the difference, when you choose one or the other. Here's everything you need to know to make the right choice.
1. BMV-712 Smart — the classic with display
BMV-712 is the traditional monitor with:
- Own LCD display (4 buttons for navigation)
- Built-in Bluetooth
- Shunt 500A (standard) or 1000A (variant)
- Auxiliary inputs (temperature, midpoint deviation, second battery)
- Price: ~190 €
Recommended when you want a visible physical display in the living room, RV, or cabin.
2. SmartShunt — the minimalist version
SmartShunt eliminates the physical display:
- It does NOT have its own display — monitoring via VictronConnect
- Built-in Bluetooth
- Shunt 500A or 1000A
- Much smaller (1/3 the size of BMV)
- Price: ~€140 (25% cheaper)
3. Decision table
| Scenario | Recommendation |
|---|---|
| RV / boat with room for display | BMV-712 |
| Home system with Cerbo GX | SmartShunt (see also in VRM) |
| Simple little cottage | BMV-712 (direct visual) |
| Large professional off-grid system | SmartShunt + Lynx Shunt VE.Can |
4. Accuracy of measurement
Both use the same calibrated resistive shunt principle. Accuracy:
- Current: ±0.4%
- Voltage: ±0.3%
- SOC (State of Charge): after calibration, ±2%
They are among the most accurate battery monitors in the industry.
