SmartBMS Utility

See every cell.
Control every charge.

The Bluetooth companion app for your Battery Management System. Real-time per-cell voltage and temperature, remote configuration, GPS speed tracking, and full history — built for solar setups, off-grid cabins, and campers, not enterprise fleets.

Smart energy management

Everything your BMS knows, right on your phone.

Connect over Bluetooth and get instant visibility into voltage, temperature, state of charge, and cycle history for every cell in your pack — then tune the system remotely instead of pulling out a laptop and a serial cable.

How it works

From pairing to full history in three steps

No firmware flashing, no serial cable — the whole workflow lives in the app.

Connect

Open the app, pick your BMS from the device list, and tap Connect. Bluetooth pairing takes seconds — no cables, no drivers.

Monitor

The Overview tab shows live per-cell voltage, temperature, state of charge, and charge/discharge status the moment you connect.

Configure & log

Switch to Configuration to tune settings remotely, or Logging to see the history the app has been quietly building in the background.

All the features you need

Built around how battery packs actually get used

From first pairing to years of cycle history, one app covers the whole lifecycle of your BMS.

Real-time overview

Per-cell voltage, temperature, state of charge, current draw, and remaining time — updated live over Bluetooth.

Remote configuration

Tune charge and discharge parameters, safety limits, and capacity settings without opening the pack.

Historical logging

Track voltage, temperature, and cycle trends over time, and spot anomalies before they become failures.

Multi-device dashboard

Monitor several battery packs — house bank, starter, solar buffer — side by side in one view.

Automation & notifications

Set triggers like "below 20% state of charge → disconnect load and notify me" and let the app react for you.

Custom themes & dark mode

Seven color themes, including a dedicated colorblind-friendly palette, plus a proper dark mode — the dashboard adapts to you, not the other way round.

GPS & speed tracking

A live speed dial next to your charge level — built for a battery that's moving, not just sitting in a cabinet.

Fault & error diagnostics

Every protection trip and error count your BMS reports, decoded into plain language instead of a blinking LED.

Inside the app

A real dashboard for a real battery pack

No mockups here — this is the actual SmartBMS Utility interface, monitoring a live battery pack.

Live per-cell voltages, pack temperature, and charge/discharge state

Remote configuration — capacity, cell voltage limits, and more

Multi-device dashboard, monitoring several packs at once

GPS speed dial with charge, range & efficiency

Built for real setups

Wherever your battery lives, so does the app

SmartBMS Utility is built for people running their own power system, not fleet managers.

Solar & off-grid

Keep an eye on a cabin or off-grid battery bank without walking out to check a panel yourself.

Campers & RVs

Know your state of charge before you're relying on it — check from the driver's seat or the campsite.

Marine & boats

Monitor a house battery bank that's harder to get to and more expensive to get wrong.

Home battery backup

Track a home energy storage setup the same way you'd track anything else you depend on daily.

From the App Store

“Great app, works exactly as I imagined. All values can be easily adjusted. I also spent money on another app, but without any additional features.”
