Multi Battery Monitor

The ultimate display for Li-Ion battery packs. Real-time Bluetooth monitoring for up to 4 batteries, tracking individual health and calculating your total State of Charge (SoC) on a single high-contrast dashboard.

Where It Can Be Used

Designed for off-grid freedom and critical power visibility, wherever you draw your energy.

Sailing & Motor Boats

Maximize your time at anchor. Monitor your service battery bank wirelessly to know exactly how much off-grid power you have left before you ever need to think about a marina hookup or running a generator.

Motorhomes & Camper Vans

Space is premium on the open road. Ditch the bulky analog gauges and heavy wiring looms for a compact Bluetooth display that lets you check your overall system SoC right from the driver’s seat.

Other Off-Grid Systems

Versatile monitoring for independent power systems. From isolated solar banks and tiny homes to remote DIY field boxes, MultiBM adapts instantly to keep any custom battery network perfectly visible.

Engineered for Total Battery Visibility

The smart, cable-free solution to track your lithium power storage

Seamless Bluetooth Pairing

MultiBM pairs instantly with your batteries using an ultra-stable, low-energy Bluetooth protocol. Simply mount the display wherever you need it, power it up, and enjoy real-time wireless diagnostics without drilling holes or pulling thick cables through your vehicle or vessel.

Up to 4-Cell Smart Tracking

Whether you are monitoring a single isolated battery or a Li-Ion pack configuration, MultiBM effortlessly scales its user interface. The display cleanly balances the layout, giving you a detailed view of individual battery performance without cluttering the screen.

Consolidated State of Charge (SoC)

MultiBM features a built-in aggregation algorithm that continuously cross-references your cell data. It handles the math for you, delivering a single, massive, easy-to-read overall SoC percentage. You’ll know exactly how much total energy is left in your entire ecosystem.
