Victron SmartShunt 300A IP65 Bluetooth Battery Monitor

The Victron SmartShunt 300A IP65 is a display-free battery monitor with Bluetooth and VE.Direct, in a sealed enclosure.

Display-free is the design choice, and it removes a gauge from a dashboard that probably has no room for one. A helm panel is usually full before anyone thinks about a battery monitor, and using a phone means no cutout, no bezel and no cable to the display.

Three hundred amps suits smaller and mid-size banks, giving better low-current resolution than a larger shunt. A shunt reads a small voltage across a calibrated resistance, so matching its range to the actual currents improves everyday accuracy.

The IP65 enclosure protects against dust and water where the standard version would need shelter. That matters because the shunt belongs in the negative cable near the batteries, and that position is often damp. Explore more battery monitoring.

• No gauge, no cutout, no display cable
• A helm panel is full before a monitor is considered
• 300A reads low currents more accurately
• IP65 suits the damp position near the batteries
