Powering vans, boats and off-grid kit. Since 2022.

Every TITAN talks to our cloud through the app. These are our best estimates of the energy and capacity TITAN packs have delivered since the brand launched in 2022 - modelled from what we measure across the live fleet today, and ticking up as you read.

Energy delivered · since 2022 · est.

3,244,540.00kWh

Tracked fleet, today: 38.00 kWh

Enough to power a town of ~1,200 average UK homes for a full year.

Capacity delivered · since 2022 · est.

249,580,000Ah

Tracked fleet, today: 3,000.0 Ah

Usable amp-hours pulled through the BMS of TITAN packs across every van, boat and off-grid setup since launch.

Solar harvest, fleet-wide

54kWh / day

PV energy our AI engine sees flowing back into solar-equipped TITANs on a typical day. That's 4,225 Ah of free charge between them.

Typical solar TITAN, daily

54.2Ah / day

Average daily PV lift across batteries our AI engine sees running on solar - free charge back into the pack, every day.

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.

01

Hand-picked cells

Top 10% of every batch. Grade A+ in everything but name. Up to 10% extra usable capacity over the spec sheet.

02

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.

03

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.

04

CANBUS & RS485

Native Victron CANBUS on every model from 105Ah up. Plug into a GX device and let DVCC do the work.

05

Self-heating

Built-in heater pads on every model. Charge safely down to -20°C without a fight.

06

Lifetime warranty

Lifetime, fully transferrable. The battery is module-based so we repair, we don't replace.
