Smart Shunts

Smart shunts are battery monitors that keep the measurement hardware at the battery and put the display on your phone instead of on the wall or dashboard. In practical terms, they give you proper battery current, voltage, state-of-charge and history data without adding another visible display head or extra front-panel clutter.

They make the most sense in systems where clean installation matters, app-based monitoring is perfectly acceptable, and the user still wants proper battery information rather than guessing from voltage alone. For many campervan, leisure and off-grid systems, that makes a smart shunt the neatest way to get serious battery monitoring without turning the install into a museum of round gauges and cut-outs.

If you are choosing between smart shunts, the key things to compare are current rating, how the data is viewed, and what extra monitoring options are available. The point is not just to count amps for sport, but to understand how the battery is being used and to make the wider system easier to manage and diagnose.
