The Victron SmartShunt gives you accurate state-of-charge readings via Bluetooth to your phone β€” not a rough voltage estimate, but a precise percentage based on actual amp-hours in and out of the battery. Essential for managing power on off-grid van life.

Why Accurate Monitoring Matters

Without a proper shunt monitor, you're guessing your battery state from voltage alone. Lithium batteries maintain flat voltage across most of their discharge cycle β€” voltage tells you almost nothing until the battery is nearly dead. The SmartShunt tells you exactly: 73% remaining, 2.3 hours at current draw.

Our Verdict

4.9/5

Know exactly how much battery you have left. Bluetooth to phone, 500A rated, works with all battery types. The most trusted battery monitor for van builds.
