The official app for TITAN lithium leisure batteries. Live readings, your whole power system on one map, alerts you define, and an AI engineer that knows your battery. Designed and built in Cheltenham. CONNECT IN SECONDS Tap your battery and TITAN pairs over Bluetooth. No codes, no hubs. Auto-Connect picks it up again every time you open the app. LIVE MONITORING See charge level and charge/discharge direction at a glance. Pack voltage, current, temperature, per-cell voltages, time to empty and time to full worked out from how you actually use the battery. ENERGY FLOW A live map of your setup drawn around your caravan, motorhome, van, boat or cabin. Solar in, wind in, engine, mains and loads out, all moving in real time. Arrange the nodes to match your kit, or send it full screen and use it as an always-on display. CONNECTED DEVICES Victron solar chargers and shunts, Mopeka tank sensors and Ruuvi climate sensors appear live alongside your battery, on the same map. Measured solar and engine input replaces estimates the moment a charger is connected. ALERTS YOU DEFINE Set your own limits for voltage, charge level, temperature and discharge current and TITAN tells you when they are crossed, in the app and in the background while Auto-Connect is on. Protection trips and low charge are always covered. HISTORY State of charge, voltage, current and temperature over a day, a week, a month or a season, with the highs and lows around the average and every protection event logged with a timestamp. TITAN AI An intelligence engine that learns your install: typical daily use, the appliances on the other end of the battery, your solar yield against the real forecast, and the slow changes that hint at a problem. Ask the AI engineer anything about your pack in your own words. It answers from your live data and TITAN's own knowledge, and it says so when it does not know. WARRANTY AND SUPPORT Your TITAN account links every battery you own. Health certificates and warranty status in one place. Report a problem from inside the app in two taps and we reply by email.
