About Us
About Voltmonk VoltMonk is the energy brand of Mohanamma Technology Private Limited. The METRION line of LiFePO4 all-in-one inverter-battery systems reached the market in 2026 — after thirteen years spent getting the engineering right first. The timeline Long before Mohanamma Technology Private Limited was incorporated in 2026, the work behind METRION had already begun — thirteen years of research into battery chemistry, thermal behaviour and manufacturing quality, done quietly before anything carried the VoltMonk name. That gap is the point. Most of what's sold as LiFePO4 in this market is imported cells in a rebadged case. METRION exists because thirteen years wasn't spent finding a supplier — it was spent understanding the product well enough to build it here, in Hosur. founder Founder, Mohanamma Technology Private Limited Thirteen years of research, one name behind it. The Problem Walk into an electrical shop in a Tier-2 or Tier-3 town across South India and ask for home backup. You'll almost always be sold a tubular lead-acid battery wired to a separate inverter — heavy, needs water topped up, and worn out years before the inverter connected to it. That's a distribution problem, not a technology one. LiFePO4 solved this years ago; it just stayed in the metros. What we make Six models, rising from a portable pack to a full home and small-business system. Every one is a single enclosure — cells, inverter and battery management system built in together, not wired up on site. METRION Pocket — MT-140P 140W A portable power pack for outages, small appliances and outdoor use. METRION Spark — MT-500S 500W Entry home backup for lighting, fans and small electronics. Mid-range models 1,000W – 3,000W — confirm exact model names and specs Scaled for larger households and small shops running multiple circuits. Higher-capacity models up to 6,000W — confirm exact model names and specs For homes or premises with heavier concurrent load. METRION Lightning — MT-12000L 12,000W The top of the line — full home or small commercial backup in one unit. where we operate mission To make LiFePO4 all-in-one power systems the ordinary choice in South Indian homes and shops, not the premium one — priced within reach of a family replacing a lead-acid inverter, and sold through a dealer close enough to actually service it. vision That a household in a district town gets the same power technology as a household in Bengaluru — from a brand that manufactures in India, rather than one that rebadges an import.Thirteen years of research, then a company.
We didn't start with a product launch. We started with a question.
