UK startup unveils industrial batteries based on repurposed EV battery packs

UK-based energy storage startup Allye Energy has announced two new battery energy storage systems (BESS) for industrial applications.

Dubbed MAX1000 and MAX1500, the new systems have a storage capacity of 1 MWh and 1.5 MWh. The MAX1000 is available for order now, with the MAX1500 launching in summer 2025.

“Unlike traditional batteries, MegaMAX range combines up to 18 repurposed EV battery packs with mixed chemistries (LFP and NMC), significantly reducing its environmental footprint while enhancing energy diversity and reliability,” the company said. “This hybrid approach also cuts embedded carbon by over 40% per unit, saving up to 100 tonnes of CO₂e.”

While the MAX1000 provides 820 kW of power’ the MAX1500 1.25 MW. The new product range can function in both on-grid and off-grid installations, and provide power and capacity as required for commercial and industrial functions.

“Each MegaMAX integrates three Allye MAX300 structures into an integrated, functional system with inherent redundancy, featuring a fully liquid-cooled thermal management system to improve round-trip efficiency, extend battery lifetime, and enhance performance,” the company said. “Each unit is a self-contained, modular ‘drop and go’ solution that can be deployed in under two minutes.”

The MAX1000 has a size of 6.17 m x 2.55 m x 3.125 m and weighs up to 12,150 kg. Its working temperature is between -10 C and 40 C, and its relative humidity range is 0-95%. The system itself has an IP54 rating, while the battery packs are IP67 rated.

The exact specifications of the MAX1500 system are not yet available.

Allye previously offered mobile BESS that also used repurposed EV battery packs in mobile 300kWh units.
