18 Seconds to Full Charge! British Battery That Could Revolutionize the EV Market

British RML Group Announces Breakthrough in EV Battery Technology – VarEVolt Cleared for Mass Production

British company RML Group has announced a major step forward in the transformation of transportation – its VarEVolt battery, previously used mainly in electric hypercars, has now received certification for mass production.

The advanced VarEVolt battery stands out not only for its extremely high power density – 6 kW/kg – but also for its unprecedented charging speed. With a C-rate of 200, it can be fully charged or discharged in just 18 seconds, making it one of the fastest power cells on the market. For comparison, the batteries used in the Porsche Taycan offer C-rates of only 4–5, which translates to charging times of 12 to 15 minutes.

A New Standard for the EV Industry?
RML received its production conformity certificate on June 2, marking the company’s readiness to enter the mass market. “This confirms our transition from the prototyping stage to large-scale production contracts,” said James Arkell, head of the powertrain division at RML Group.

Until now, the VarEVolt was a niche solution – powering, for example, the futuristic hybrid hypercar Czinger 21C. Now, thanks to its scalable, modular design, the battery has the potential to be used in a wider range of vehicles – from high-performance EVs to urban passenger cars.

“We can tune the battery to meet manufacturers’ needs – focusing on range, power, or finding an optimal balance between them,” explained Paul Dickinson, CEO of RML Group. This design flexibility gives automakers the freedom to build vehicles tailored to specific customer needs.

A Shift for Automotive Classics Too
Interestingly, RML is also planning conversion kits for older-generation supercars. Board member Michael Mallock announced the development of replacement packs for legacy models like the LaFerrari and McLaren P1. “We can offer a kit that significantly extends range, and with the right hardware, it’s possible to achieve up to eight times the original power output,” he said.

What’s Next?
While VarEVolt remains a top-tier technology for now, entering the serial production phase could significantly improve its availability and future applications. Could cutting-edge batteries from hypercars soon find their way into more accessible EV models? RML makes it clear that this scenario is becoming increasingly realistic.
