How MAX works
One system, two ways to work.
Battery as a buffer
- Charge off-peak or from solar.
- Boost peak power above your limit.
- Back up the site in under 40ms.
- Earn from grid flexibility markets.
Battery as a generator
- Charge from DC, a MAX or a generator.
- Power quietly, zero local emissions.
- Top up from a generator if needed.
- Save fuel, run hours and emissions.
Deployment and transport
Tow it, lift it or drop it.
No concrete pad, fencing or crane. Every MAX is pre-commissioned in our factory, running in minutes, and moves when the job does: permanent, semi-permanent or fully mobile.
Tow and Go
<3.5tUnder 3.5t on its integrated trailer, towed on a standard licence.
Lift into place
10ftCompact 10ft footprint, lifted into place on chains and hooks.
Drop and Go
<2 minLowered from a hooklift truck in under two minutes, no crane.
Classified UN3536
Battery storage on the road is normally a Class 9 dangerous good, with paperwork on every move. Working with DfT, VCA and a safety adviser, each MAX is classified UN3536: users display the plate and Class 9 label, with no wider ADR obligations.
Fits a parking bay
MAX300 is under 2m tall and fits a standard parking bay, with no pad, fencing or groundworks for stationary use.

Why MAX
More than a battery in a box.
A standalone battery stays where it is built and does one job. MAX powers sites, charges vehicles and moves between jobs.
| Allye MAX | Standalone BESS | |
|---|---|---|
| Capacity | 328kWh to 1.5MWh, up to 1.26MW per unit | Sized for one fixed site |
| Integrated EV charging | Up to 1.28MW DC with two outlets, plus AC | Separate chargers needed |
| On-grid and off-grid | Both, with UPS switching in under 40ms | Typically grid-tied only |
| DC recharging | From a DC charger or another MAX, zero diesel | Not applicable |
| Installation | Tow, lift or drop; no pad, fencing or crane | Crane, concrete pad and fencing |
| Moves with the work | Yes: redeploy to the next site in minutes | Stays where it is built |
| Planning | MAX300 under 2m, fits a parking bay | Often needs planning |
| Transport | UN3536: users need only the plate and label | Class 9 dangerous goods under ADR |
| Batteries | Repurposed automotive packs, ECE R100, 60% lower embedded CO2 | New cells, typically imported, higher embedded CO2 |

Two ranges, two jobs
Need a dedicated charger at the depot?
MAX powers anything, anywhere. When you need rapid charging that stays put where your fleet parks, that is the Allye MEV: 200 or 300kW of DC charging from the supply you already have.
| MAX300 | MAX300 with DC charging | MEV | |
|---|---|---|---|
| Job | Stores and supplies energy | Stores energy and charges vehicles | Charges vehicles |
| Moves | Towed on a standard car licence, or fixed | Towed on a standard car licence, or fixed | Fixed in use; lifted out and re-sited |
| Vehicle charging | Feeds separate chargers | Integrated, up to 400kW DC | Integrated, 200 or 300kW DC |
| Site power | Yes | Yes | No, charging only |
| Best for | Construction, events, film, sites that move | Temporary sites and mobile fleets | Depots and fleet bases |
