BMPRO Battery Monitors & Volt Meters: Smart 12V Power Visibility

When you're miles from the nearest campground hookup, knowing the true state of your 12V battery isn't just convenient — it's essential. BMPRO has built its reputation around giving RV and caravan owners precisely that kind of insight, and their battery monitors and volt meters sit at the heart of that mission. Backed by over 50 years of experience in power solutions, BMPRO approaches battery monitoring not as a standalone gauge, but as an integrated window into your entire onboard power ecosystem.

A Range Built Around How RVers Actually Use Power

BMPRO takes a notably broad approach to battery monitoring, recognizing that no two rigs or users are alike. Their lineup spans wall-mounted display units, Bluetooth-enabled wireless monitors, and app-driven devices — covering everything from quick at-a-glance voltage checks to deep, data-rich power management.

• RVView2 — A wall-mounted monitor designed to work in tandem with BMPRO's BatteryPlus35-II battery management system. Its backlit display shows volts, amps, charge and discharge status, and the active input source (mains, solar, or auxiliary), making it easy to understand your power picture at a glance.
• Trek3 — A wall-mounted unit that monitors and displays volts, amps, charge and discharge status, auxiliary and solar currents, and remaining battery capacity. It also allows users to configure charging parameters for both lead-acid and LiFePO4 lithium battery chemistries directly from the display.
• BatteryCheckPRO — BMPRO's flagship wireless monitor, using Bluetooth LE technology to stream real-time battery data to a smartphone app. It covers state of charge, voltage, temperature, charge/discharge current, state of health, and estimated time remaining — all from your phone. It supports continuous current ratings of 240A with a peak of 300A, making it well-suited for high-draw appliances like inverters and microwaves.
• JControl — A digital display and control unit that connects to BMPRO's J35 or ASPower systems, providing battery and water tank information and supporting LiFePO4 battery configuration with adjustable capacity settings from 50Ah to 600Ah.

Designed for Deep Cycle Chemistry, Not Just Engine Starts

A key distinction in BMPRO's battery monitor lineup is that these products are purpose-built for deep cycle secondary batteries — including lead-acid AGM, Gel, and lithium LiFePO4 chemistries — rather than engine cranking applications. This focus means the monitoring algorithms and display data are calibrated for the gradual charge-and-discharge cycles that define off-grid RV living, delivering accuracy where it matters most.

BMPRO is widely recognized as one of the pioneers of using digital platforms in RVs, with one of the largest install bases of smart power management systems globally. Their monitors are designed to integrate seamlessly with the broader BMPRO ecosystem — pairing with battery management systems, solar inputs, and smartphone apps for a unified view of your rig's power health.

App Connectivity and BYOD Support

Several BMPRO battery monitors connect with dedicated iOS and Android apps, allowing users to monitor their battery in real time remotely. The app-driven approach lets you set battery type and capacity, adjust reserve thresholds, and track trends over time — going well beyond what a simple volt meter can offer. For those who prefer wall-mounted convenience, BMPRO's display units provide instant readouts without requiring a phone.

Whether you need a simple panel-mounted readout or a full Bluetooth-connected monitoring suite, BMPRO's battery monitors and volt meters give RV owners the confidence to push further off the beaten path.
