  • Safety — on an internal short circuit the LTO negative electrode turns highly resistive, minimising the current flow that can lead to rupture or fire.
  • Long life — 20,000+ cycles, capacity ≥ 70% even after 20,000 charge/discharge cycles.
  • Rapid charging — to about 80% of capacity in roughly 6 minutes.
  • Low-temperature operation — usable even at −30 °C, with almost no lithium-metal deposition.
  • High input/output — captures regenerative-braking energy and supplies high pull-away current.
  • Wide usable SOC — the full 0–100% range, so a system needs less installed capacity.

Tested on ourselves first

Qualified the hard way — on our own fleet and grid.

Cells, tyres and chargers earn their place by surviving our own duty cycles first, under automotive-grade quality systems and logged to the AI audit trail. What we ship has already proven itself inside the system.

One system

This is how the system feeds itself.

Watch one cell do two jobs: the same Japanese LTO chemistry drives a bus by day and firms a city’s peak in an Energy BESS by night. The stations built on this floor are bolted to corridors and run by the operated Network. And a tyre that has worn out on the fleet comes back through pyrolysis as carbon black for new rubber, oil that goes to Energy as fuel, and steel for recycling. Three hand-offs you can point to — not a slogan about a system.

What it’s all for

A battery that lasts a livelihood.

Extreme cycle life and high intrinsic safety mean the pack outlives the loan — power a driver can depend on, day after day.

For the people who depend on the hardware

Build on what we build.

For capital, for manufacturers and operators, and for the people who depend on hardware that simply holds.

Questions

Frequently asked

What battery chemistry do Ampinity cells use?

The cells and packs are built on proven Japanese LTO (lithium titanate) cell technology — an intrinsically safe chemistry with a 20,000-cycle life, an ~80% charge in about 6 minutes, the full 0–100% usable range and −30 °C operation.

Can the same cell serve both vehicles and grid storage?

Yes — the same chemistry that drives a truck can hold a city's evening peak, feeding traction for buses, trucks and LMVs and storage for Energy's BESS from one engineering line, so a fleet and a grid operator buy the same proven cell.

What is the pack architecture?

The architecture uses liquid-cooled modules and packs up to 660 V, BMU-managed.

How is cell quality assured?

The cells carry automotive-grade quality (IATF16949 / ISO9001) and are recorded on the immutable audit trail, backed by AI Assurance.
