What Enix Power Solutions does

Enix Power Solutions is a UK-based custom battery pack designer and manufacturer, operating as a division of the UPERGY group (legal entity UPERGY LIMITED, England, Company No. 2045875) and reporting over thirty years of operating history. The company sells bespoke battery packs, in-house Battery Management Systems (BMS) and Protection Circuit Modules (PCM), and certification support to OEM device manufacturers, with a stated addressable vertical set spanning medical devices, drones/UAVs, robotics, instrumentation, marine/subsea/oceanographic, alarm and security, building automation, e-mobility and oil and gas. Operations are anchored by a manufacturing and headquarters facility in Solihull, England, with additional sales and support offices in Saint Egrève, France, and Gavà (Barcelona), Spain, and a trilingual English/French/Spanish web presence.

The technical core is multi-chemistry pack assembly across nine distinct battery technologies: Lithium-Ion, Lithium Iron Phosphate (LiFePO4), Lithium Polymer, Lithium Thionyl Chloride (Li-SOCl2), Lithium Manganese Dioxide (Li-MnO2), Lead Acid (AGM and Gel), Lead Crystal, NiMH and Alkaline. Engineering capability extends to BMS/PCM design for cell balancing and over/under-voltage protection, and to in-house certification to UN38.3, IEC 62133, IEC 62619, UL 2054 and ISO 13485 (aligned with ISO 60601 for medical devices). The product portfolio combines proprietary NX-branded standard cells and packs (NX-Power alkaline, NX NiMH, NX Lead Acid, NX Lead Crystal) with official distribution and assembly of partner-brand cells from Saft, EnerSys, Panasonic, Procell, Varta, Yuasa, Tadiran, Ultralife, GP Batteries, Maxell and Engineered Power.

The business model is sales-led direct engagement with OEM customers, with bespoke project pricing quoted per enquiry (no public price list, no e-commerce). Revenue is generated through one-time hardware sales of custom-configured packs plus repeat orders from device lifecycle replenishment, supplemented by standard pack and cell sales through partner-brand distribution and by professional services revenue from assisted certification. Marketing is conducted via the multilingual corporate website, downloadable brochure, LinkedIn presence and direct sales contacts in each of the three operating geographies, with no disclosed marketplace or third-party platform distribution.
