Pouch High-Power Cell
Advantelec 3S300-32
Pouch cell delivering 32 Ah capacity, 301 Wh/kg energy density and 96 A maximum discharge rate.
Overview
The Advantelec 3S300-32 is a high-power Li-ion pouch cell designed for applications that demand sustained high current. Released in 2026 and with the manufacturer based in France, this pouch cell delivers 32 Ah capacity and 116.8 Wh of energy at a nominal voltage of 3.65 V, with a maximum continuous discharge capability of 96 A, making it well suited to high-power systems. A gravimetric energy density of 301 Wh/kg puts it at the upper end of the library. The silicon-bearing anode contributes to that energy density.

Motorsports
McMurtry Automotive: Faster cell evaluation
McMurtry Automotive used The Voltt and validated cell models to evaluate the transition from the Molicel P45B to P50B during early pack concept development.
Side by side modelling enabled rapid comparison of electrical and thermal behaviour, avoiding lengthy physical test campaigns. This approach reduced cell evaluation time by seven months, allowing the team to lock in cell selection and pack assumptions earlier while lowering technical risk and accelerating vehicle development.

Manufacturer Background
Advantelec
Advantelec is a French lithium-ion cell and battery system manufacturer
Advantelec is a French battery manufacturer founded in 2011 and headquartered in Vénissieux, near Lyon, designing lithium-ion pouch cells, battery packs with integrated management systems, and supporting electronics for professional applications. Its ADV-POWER® range spans NMC and semi-solid-state pouch chemistries, with high-energy variants reaching gravimetric energy densities of 340–350 Wh/kg. The company supplies rugged battery systems for uncrewed aerial vehicles, medical instrumentation and industrial equipment, where certification and traceability matter as much as raw performance. In 2024 Advantelec commissioned a pilot cell production line near Lyon, moving from pack integration into domestic cell manufacture and reducing its dependence on external cell suppliers. That vertical step positions the company as one of a small number of European producers offering sovereign supply of high-energy pouch cells for defence-adjacent and professional UAV programmes.
