All over Bluetooth, no display to fit
Where the BMV-712 Smart from the same brand relies on a physical display, the SmartShunt takes the opposite approach: no readout on the unit itself, with all data running over Bluetooth to the VictronConnect app on a smartphone or tablet.
99.6% claimed accuracy, manufacturer data
Victron states 99.6% accuracy for this calibrated 500A/50mV shunt, identical to the one in the BMV-712. The unit continuously measures voltage, current in and out, state of charge and estimated remaining time, keeping a 30-day history of use. This accuracy figure remains manufacturer data, with no independent measurement or drift tracking to confirm it over time.
Native Bluetooth and a detailed app, no dongle to buy
Bluetooth is built into the housing natively, with no add-on module to buy separately, unlike several rivals that sell it as an option. The VictronConnect app shows state of charge, estimated remaining time and a detailed discharge history. VE.Smart Networking also lets it wirelessly share temperature and voltage data with other compatible Victron equipment. One point worth knowing: firmware updates have sometimes stalled part-way through for some users.
IP65 and wide chemistry compatibility, no display cable to run
The IP65-rated housing resists dust and water splashes, a step up from the BMV-712's IP55, making it particularly suited to marine installations, vans or any damp battery compartment. The unit is compatible with lithium, AGM and flooded lead-acid batteries. The lack of a physical display also simplifies installation: no display cable to run to the dashboard, only the shunt itself needs wiring to the battery's negative terminal.
A 5-year warranty, but no relay or built-in alarm
Victron warrants the unit for 5 years, the same duration as the BMV-712. The notable difference lies in active safety: unlike its display-equipped sibling, the SmartShunt offers no programmable relay or audible/visual alarm on the unit itself. Any low-battery alert depends entirely on the app and a phone being nearby and switched on.
Against the BMV-712, the Renogy RBM500 and the AiLi 500A
How does the SmartShunt compare with other battery monitors?
| Criterion | SmartShunt 500A | Renogy RBM500 | Victron BMV-712 | AiLi 500A |
|---|---|---|---|---|
| Native Bluetooth | Yes, built-in | No (module optional) | No (module optional) | No |
| Physical display | None (app only) | Wired LCD | Dedicated LCD | Wired LCD |
| Rating | IP65 | Not stated | IP55 | Not stated |
| Warranty | 5 years | 2 years | 5 years | Not stated |
| Observed price | £85.95 | £54 | £127.40 | £72 |
The BMV-712 shares the same shunt but adds a physical display and an alarm relay, for noticeably more. The Renogy RBM500 stays significantly cheaper, but with no stated water resistance and a warranty limited to 2 years. The AiLi 500A sits between the two, with no native Bluetooth or stated rating. For a modern, water-resistant install run entirely from a smartphone, the SmartShunt remains the best technical compromise in this line-up.
Who the Victron SmartShunt 500A is for
This monitor suits anyone happy to run everything from a smartphone and wanting a discreet install with no display cable to run, ideally in a damp environment thanks to the IP65 rating. For a permanent physical display and a built-in alarm relay, the BMV-712 Smart from the same brand remains the reference; for a tighter budget at the cost of an unstated water rating, the Renogy RBM500 is an alternative.
