Aceleron

Aceleron is a manufacturer of lithium battery technology for energy storage and power solutions, distinguished by its patented compression-based core design that enables fully maintainable, upgradeable, and scalable battery systems built on circular economy principles. The company's flagship product, The Essential, is a Group-31 standalone battery available in 12V 115Ah, 24V 57Ah, and 48V 28Ah configurations, utilizing cobalt-free Lithium Iron Phosphate chemistry with up to 5,000 cycles at 100 percent depth of discharge. The Essential's modular core can be easily removed for servicing or swapped for an upgraded core, reducing through-life costs and raw material consumption while extending product lifespan. Weighing 15 kilograms, the battery is approximately half the weight of comparable lead-acid products, making it ideal for mobile applications including motorhomes, electric all-terrain vehicles, and remote telecom stations. Aceleron also offers the Offgen battery system for stationary energy storage at 11.2 kWh capacity. The company's products are independently tested by specialist centers and designed for multiple mounting orientations. Founded in 2018 and headquartered in London, United Kingdom, the company has raised $13.0M in Series A funding from investors including Midlands Engine Investment Fund, BGF, and Mercia.
