BankManager Monitor Introduction and mini tutorial video
BankManager Monitor — Getting Started
A short tutorial for boat owners using BankManager Monitor, the companion app for BankManager marine battery monitoring.

What the app does
BankManager Monitor connects to your BankManager over Bluetooth and shows:
- Live lithium (Li) and lead-acid (Pb) voltages
- Current (amps) and percent of charge (POC)
- Whether the banks are connected
- A history chart backed by a local archive on your phone or computer
The app is read-only: it monitors the BankManager; it does not control charging or contactor settings.
Battery history stays on your device. It is not uploaded to DeTra’s servers as part of normal monitoring. You can export a file yourself if you want a backup or to share data.
What you need
- A powered BankManager within Bluetooth range
- BankManager Monitor installed (iPhone, iPad, Android, or Mac)
- Bluetooth turned on, and permission allowed when the app asks
On a boat, metal bulkheads and distance matter. Stay relatively close for the first connection.
First connection
- Open BankManager Monitor.
- Tap Connect BLE (top of the Live screen).
- In the Connect BankManager sheet, wait for nearby devices, then select yours.
- When the status shows Connected, live tiles begin updating.
- After connect, the app may briefly load history from the BankManager’s onboard buffer. A small progress indicator can appear while that runs.
To stop streaming, tap Disconnect. Archived samples already saved on this device remain until you clear or export them.
Reading the Live dashboard
| Reading | Meaning |
|---|---|
| Li | Lithium / LFP bank voltage |
| Pb | Lead-acid bank voltage |
| Amps | Positive = charging · Negative = discharging |
| POC | Percent of charge |
| Connected | Contactor / bank connection state from the BankManager |
Tap the ⓘ icon next to Connected / Not Connected for a short connection summary (BLE link and bank state).
Chart and history
- Use the range chips (3h, 6h, 12h, 24h, 7d, 30d, 90d, All) to change the visible window.
- You can pan and zoom the chart to inspect peaks, loads, and charge periods.
- Samples are stored locally so history can outlive the BankManager’s limited onboard ring buffer.
How long Live samples are kept is controlled in Settings (retention). Defaults are conservative; you can keep more history if you want.
Menu: Datasets, Insights, Settings, About
Open the menu (drawer) from the Live screen.
Datasets
- Browse Live capture and any archives you imported.
- Import… brings in a previously exported file.
- Switch views to compare Live data with an older trip or backup.
Insights
Summaries over 7 days, 30 days, or all archived data—for example energy (lithium Ah), POC behavior, charge quality, and link health. Insights need enough samples in the chosen range; capture or import history first if the page says there isn’t enough data yet.
Settings
- Export… — save Live capture as a JSON archive (for backup or sharing).
- Clear Live archive — permanently deletes Live samples on this device (BLE disconnects; imported datasets are kept).
- Chart amp scale, display time zone, and other display preferences.
- On phone: options related to background capture / notifications where the OS supports them.
- On Mac: hide-window vs quit behavior (see below).
About
Version, Alpha expiry (if applicable), links to the BankManager product page, and the install/operations video.
Phone tips
- Keep Bluetooth on while you want live capture.
- On Android, an ongoing notification may appear while capture is active—that’s how the OS allows background work.
- If the app can’t find your BankManager, confirm nothing else is already connected to it, then try again closer to the device.
Mac tips
- Closing the window can leave the app running so capture continues, depending on your setting to keep the Dock / menu bar available.
- Use Quit (Settings or the app menu) when you want capture to stop completely. Archived history on the Mac is kept.
- The status item (menu bar) can reopen the window if you hid it.
Quick FAQ
Does this control the BankManager?
No. Monitoring and history only.
Where is my data?
On this phone or computer. Export creates a file you choose to save or share. See the Privacy Policy for details.
Why did live updates stop?
Disconnect, Quit, Bluetooth off, or out of range will stop the live stream. History already archived remains until you clear it.
Can’t see my device in the scan list?
BankManager powered, Bluetooth on, app permission granted, nearby, and not stuck connected to another phone or computer.
What is Alpha?
Some builds are labeled Alpha and may show an expiry date under About. Install a newer build before that date if you want continued use of that channel.
