Voltagen Battery Monitor is the companion app for Voltagen Lithium battery power systems and legacy Volta Power Systems. Connect to your battery system over Bluetooth for real-time monitoring, or check in from anywhere using cloud-based remote access (requires two devices). A Voltagen Bluetooth adapter is required to use the app, check with your manufacturer or Voltagen Support to verify your system is equipped. **Real-Time Dashboard** See your battery's state of charge, voltage, current, capacity, and temperature at a glance. An animated gauge and color-coded indicators make it easy to understand your system's health without reading a manual. **Power Flow Visualization** Watch energy flow through your system in real time. See exactly where power is coming from — shore power, alternator, or battery — and where it's going. Shore power connection type (20A, 30A, 50A) is shown automatically. **Inverter & Shore Power Control** Turn your inverter on or off and set your shore power breaker rating directly from the app. The breaker selector adjusts automatically to your system's supported range. (Only support on some configurations) **Remote Cloud Monitoring** Stream your battery data to the cloud and check on your system from anywhere. Perfect for monitoring your RV while you're away, or keeping an eye on multiple installations. No special hardware needed — just connect over Bluetooth and tap Cloud Send. **Power History** Track your power consumption over time with a built-in history chart. See average power draw minute by minute over the last hour to understand your usage patterns. **Fault Alerts & System Status** Know immediately when something needs attention. The app displays active faults from your Battery Management System, last shutdown reason, and system health indicators so you can address issues before they become problems. **Multiple Device Support** Manage multiple Voltagen battery systems from a single account. Claim devices, switch between them, and monitor each one independently.

Verdict

The call

The clearest difference is update cadence: Voltagen at fortnightly against Devos's every 6 months. Voltagen also leads on iOS requirement (13.0 vs 15.0). Devos's advantage is ratings volume (65 vs 4) and rating (4.7 vs 4.5). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Devos holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Devos has 65 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 94% of Devos's written reviews are positive against 100% of Voltagen's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Devos ships an update every 6 months, Voltagen fortnightly. The most recent releases landed on August 20, 2026 and September 13, 2026 respectively.
