Take full control of your TITAN lithium battery with the official TITAN app. Live state of charge, real-time current and per-cell voltages - plus an always-on AI that watches for the issues that quietly kill lithium packs. CONNECT IN SECONDS Tap the battery in your garage view and TITAN bonds over Bluetooth -no codes, no setup. Auto-reconnect picks it back up automatically the next time you're in range. LIVE MONITORING • State of charge dial with charge / discharge direction at a glance • Pack voltage, current and temperature in real time • Per-cell voltages with imbalance highlighting • Time-to-empty and time-to-full estimates from your actual usage BMS PROTECTION TRACKING Every protection event the battery management system fires is logged with a timestamp, so you can see exactly what happened: short-circuit trips, cell over- and under-voltage, MOSFET faults, charge and discharge over-current, charge and discharge over- and under-temperature, and IC errors. TITAN AI - DIAGNOSTICS THAT THINK Optional AI that learns your usage and warns you about: • Cells drifting apart - the earliest sign of a failing pack • Parasitic draws and overnight battery drop • Charger output dropping or charge cycles stopping early • Solar panels under-producing for the conditions • Pack temperature trends and MOSFET hot spots • Recurring protection events that suggest a deeper fault • Calibration prompts to keep your SoC reading accurate WARRANTY & SUPPORT Your TITAN account links every battery you own. Health certificates, order history and warranty status are all in one place - no paperwork to lose. PRIVACY-FIRST Sign in with a one-time email link - no passwords. Your battery data stays on your device unless you sign in to sync.

If the Bluetooth link drops, TITAN now keeps trying until it has your battery back, and tells you it is working on it. Previously a single failed attempt was enough for it to give up and wait for you to reconnect by hand. Also in this update: • The Data view no longer opens blank, and no longer goes blank if a battery drops out. It always tells you what it is doing and fills in the moment your readings arrive. • Whichever colour scheme you pick is now the one you get every time. Diamond in particular used to last only until you closed the app. • Light mode looks right on every screen. Connecting screens were drawing a dark panel over the light theme. • A battery left sitting undisturbed is no longer reported as having stopped responding. That warning now takes far more evidence before it says anything. • The charge percentage warning clears properly once a charge has finished, and the advice behind it has been corrected: let a charge complete rather than unplugging the moment it reads 100%. Nearly all of this came from customers writing in. Keep it coming. ### 2.3.3 — 2026-08-20 Every alert kept, every battery connected. Notification History: tap the bell on the TITAN tab to read back everything TITAN has told you, in the original wording, with the time it happened. Anything you have not seen is marked new. Steadier bank connections: if you run more than one battery, they now connect one at a time instead of competing for the Bluetooth radio, and a battery that does not answer straight away gets a second attempt rather than being reported out of range. Faster first readings: your dials fill in as soon as the battery answers. Fewer repeat alerts: a fault you have already been told about stays quiet. Your monthly summary now reports what your batteries actually delivered over the month, in amp hours and kilowatt hours, with your closing charge and health. Turn it on in Settings, under Notifications. Live Stats now counts every battery you own, not just the one you are connected to, and keeps working when you are away from the van. The app now has multiple EU languages - go to Settings > select language TITAN AI answers in German, French, Spanish, Italian and Dutch, including when you are offline. ### 2.3.2 — 2026-08-03 Wind turbines now sit alongside solar in TITAN. Declare your turbine and the app forecasts wind speed, estimates your daily yield and shows it turning on the Energy Flow map. Also in this update: • New appliances: blenders, oil-filled radiators, panel heaters and water distillers • Heaters with low, medium and high settings: TITAN learns your real wattage • Guides from titanlithium.co.uk now appear where they are relevant • A clearer, kinder experience if your battery ever runs critically flat • Fewer false alarms: a normal day of use is no longer mistaken for an overnight drain ### 2.3.1 — 2026-07-17 More brands, one map. Connected Devices now supports Renogy, Thornwave, Gobius, Safiery, EcoFlow and Simarine alongside Victron, Mopeka and Ruuvi. Run two or more solar chargers and TITAN sums their output with per-charger detail. Also: steadier reconnecting on iOS, and stability fixes. ### 2.3.0 — 2026-07-07 A big one. TITAN now sees your whole rig, not just the battery. Connected Devices: add Victron, Mopeka and Ruuvi Bluetooth sensors Energy Flow Monitor: a live view of power moving around your setup Measured charging: real solar and engine readings, no more guessing TITAN AI can now name your always-on gear like routers and Starlink Hot weather warnings alongside the existing cold ones Tidier settings, a keep-screen-awake option, and accuracy fixes throughout Open the app for the full tour. ## More apps by TITAN Lithium - [TITAN Lithium (Legacy)](https://appshunter.io/ios/app/titan-lithium-legacy/id6448871784) All apps by TITAN Lithium: https://appshunter.io/developer/1691499020 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
