BMS engineered in Cheltenham
Built different
Six things no one else does.
Most lithium batteries are a bare cell pack with a generic BMS bolted on. Ours aren't. Every spec below is standard, on every model.
Custom TITAN BMS
Designed by us to match the cells we use. Highest mosfet count in class, lifted heat sinks, anti-vibration silicone everywhere it matters.
Secure comms package
A unique data layer means third-party apps can read but never write. No stranger can hibernate your battery or push it into a danger zone.
CANBUS & RS485
Native Victron CANBUS on every model from 105Ah up. Plug into a GX device and let DVCC do the work.
Self-heating
Built-in heater pads on every model. Charge safely down to -20°C without a fight.
Lifetime warranty
Lifetime, fully transferrable. The battery is module-based so we repair, we don't replace.
Receipts · Live
Our office runs on our batteries.
Computers, servers, printers, fridges, the lot. Stored on our upcoming 48V 105Ah pack via a Victron Multiplus II, charged overnight on Economy 7. The graph on the right is live, not a marketing render.
New · TITAN App V2
A battery monitor with on-device AI.
Live SOC, per-cell voltages, secure battery claiming and an AI Engineer trained on TITAN data. Designed and built in Cheltenham. Free, no in-app purchases, works with every TITAN battery built since 2024.
World record · 8,500km
Two batteries. One ocean.
Ocean Revival rowed from the Americas to Africa raising funds for Fisher House, powered by two TITAN 120Ah batteries. Capsizes, salt, weeks at sea - and a new world record at the end of it.
