Full Review
The Victron SmartShunt gives you accurate state-of-charge readings via Bluetooth to your phone — 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 — voltage tells you almost nothing until the battery is nearly dead. The SmartShunt tells you exactly: 73% remaining, 2.3 hours at current draw.
