Tattu APP: Bluetooth battery monitoring for smart packs

The Tattu APP connects to Bluetooth-enabled Tattu smart batteries and turns the data already inside the pack into a readable dashboard on your phone. Instead of guessing whether a battery is healthy before a mission, you can check cell voltages, cycle count, temperature and firmware on the bench or at the field.

What the dashboard shows

The battery information screen reports total voltage, individual cell voltages, remaining capacity, cycle count, temperature, firmware version, manufacturing date and serial number. A status line marks the pack as healthy or warns about an out-of-range cell, an over-temperature event or a firmware mismatch, so a weakening pack is caught before it costs a flight.

Which Tattu packs support the app

Compatibility depends on the pack's BMS rather than on capacity: Bluetooth smart packs, including the G-Tech range, report live data, while standard LiPo and LiHV packs have no radio and are checked with a charger or a balance meter. If you are unsure whether a pack is app-compatible, check its product page in the Tattu battery catalogue or ask us before ordering.

Install, pair and update

Scan the App Store or Google Play code on this page, install the app and allow Bluetooth and location permissions, then power the pack and pair within a few metres. Keep the app open during a firmware update and do not disconnect until the progress bar finishes. Firmware files and manuals for other products are in the Tattu battery download centre, and our FAQ covers the questions we receive most about charging, storage and pack life.
