This brochure presents Mettle Energy as an OEM partner for low-voltage LFP battery packs. It describes the company's manufacturing facility in Surat, India, with a 12 PPM cell feed rate and 5 GWh annual capacity, promoted by the Salona Group and JB Group.
This is a corporate brochure from Mettle Energy Limited, an OEM manufacturer of low-voltage LFP battery packs based in Surat, India. It is intended for established brands that want to outsource battery pack production to their own designs and standards, with the packs carrying the client's brand name.
The brochure introduces Mettle Energy's promoters: the Salona Group (founded in Coimbatore in 1994) and the JB Group (Jay Bharat, founded in Surat in 1985), with a combined group turnover of US$600 million, over 6,000 employees and 300+ MW of solar EPC installed. The company produces packs from 100 to 314 Ah cells, in 4S to 16S configurations.
The manufacturing section describes a six-step process from cell sorting to end-of-line testing, including stacking, busbar fitting, laser welding and pack assembly. The plant uses automated welding, plasma cleaning and CCD weld inspection, with a capacity of 12 PPM and 15,000+ packs tested per month.
Four partnership models are outlined: build to print (client provides design, BOM, BMS and enclosure), job work (client supplies cells and materials), full supply (Mettle sources to client's approved list) and co-development (joint design refinement). All designs, BOM and pricing stay under NDA.
Applications covered include home and commercial backup, solar storage, telecom and electric mobility. The brochure describes enclosure formats (wall-mounted, rack-mounted, floor-standing or vehicle-tray fitted) and certification support for India (BIS IS 16046, EPR), electric mobility (AIS-IS6), stationary storage (IEC 62619, IEC 62933, IEC 61427, UL 1973) and transport (UN 38.3).
Quality procedures include incoming cell grading, in-process plasma cleaning and CCD weld inspection, end-of-line charge-discharge and BMS protection tests, and outgoing sampling with test reports per serial number and 8D analysis for field returns.
