Hyperion Link is the companion app for the Battery Gateway.

The Battery Gateway collects data from your batteries over Bluetooth and sends it to your chartplotters over an NMEA 2000 network. It is compatible with a wide range of chartplotters, including Garmin, Lowrance, and other manufacturers, so your battery information appears right alongside your other instrument data at the helm.

Use Hyperion Link to set up and manage the Battery Gateway from your phone: choose which batteries it reads, watch live battery data, check the health of the NMEA 2000 connection, and keep the gateway firmware up to date.

SEND BATTERY DATA TO YOUR CHARTPLOTTER
The Battery Gateway publishes battery voltage, current, state of charge, and temperature onto the NMEA 2000 bus, so compatible chartplotters from Garmin, Lowrance, and other brands can display it.

LIVE BATTERY DATA ON YOUR PHONE
See voltage, current, state of charge, and temperature for every connected battery in real time, even when you are away from the helm.

MANAGE YOUR GATEWAYS
Save your Battery Gateway devices (up to 8) and reconnect automatically when you reopen the app. Rename, refresh, and remove gateways from a simple device list.

CHOOSE YOUR BATTERIES
Discover nearby batteries through the gateway and add them in a couple of taps. Remove a single battery or clear them all just as easily.

NMEA 2000 / CAN DIAGNOSTICS
A live diagnostics screen shows the gateway and NMEA 2000 / CAN bus health at a glance, so you can spot wiring or network problems quickly.

BACKGROUND MONITORING
Keep monitoring after closing the app using a foreground service with a live notification, so you do not miss important changes.

FIRMWARE UPDATES
Check for and install gateway firmware updates directly from your phone, with per-component progress and release notes.

WORKS OFFLINE
Your device list and battery history are stored on your phone. No account and no internet connection are required for monitoring.

LIGHT AND DARK THEMES
A clean interface that adapts to your system appearance.

REQUIREMENTS
Hyperion Link sets up and manages the Battery Gateway hardware and has no functionality without a gateway. Bluetooth must be enabled. On Android, location permission is required by the system for Bluetooth scanning.

PRIVACY
The app talks directly to your gateway over Bluetooth and stores data locally on your device. It does not require an account.
