Terra Supreme Battery

Terra Supreme Battery is the companion app for batteries equipped with our eBM (electronic Battery Monitor) chip.

Pair your battery once by scanning its QR code, and the app shows you what you care about:

• Live voltage, temperature, and state of charge
• A low-voltage alert before your battery lets you down
• Warranty status and manufacturing details, always on hand

Switch between multiple batteries with a tap — handy for anyone with more than one vehicle, boat, or piece of equipment.

Your data stays on your phone. No account, no sign-in, no cloud.

REQUIREMENTS
A Terra Supreme battery with eBM (sold separately), an iPhone with Bluetooth, and iOS 14 or later.
