The Victron Energy SmartShunt 2000A/50mV is an all-in-one battery monitor without a built-in display, using your phone as the screen. It connects via Bluetooth to the VictronConnect app, or alternatively to a GX device through a VE.Direct cable, letting you track state of charge, time to go, and historical battery data.
Rated for a 6.5-70VDC supply range and up to 2000A, with IP21 protection, it also monitors a second battery, midpoint, or optional temperature sensor. It's a clean, low-clutter alternative to a traditional BMV battery monitor, well suited to marine, RV, and off-grid systems needing reliable, wireless battery monitoring.
