Coulomb Litech, a homegrown battery technology startup, has successfully raised ₹20 crore in a seed funding aimed at accelerating its growth in India’s rapidly evolving electric vehicle (EV) ecosystem. The fresh capital will fuel the company’s plans to expand its manufacturing capacity and deepen its footprint across commercial EV segments.
Founded in 2020 by Indian Institute of Technology (IIT) Kanpur alumni Ameya Sathe and Darshil Dharod, Coulomb Litech is focused on developing advanced battery systems tailored for medium and heavy-duty electric vehicles. The startup’s technology emphasizes fast charging and enhanced battery longevity — two crucial factors for commercial fleet operators and electric utility applications.
Coulomb’s portfolio includes modular battery solutions that operate across a wide voltage range, from 51 V to 700 V, with capacities reaching up to 80 kWh. These systems are designed to meet the demanding power and performance requirements of electric tractors, construction machinery, material-handling equipment, electric three-wheelers (E-3Ws), and stationary energy storage systems. Several of these solutions are already deployed in commercial and pilot projects with original equipment manufacturers (OEMs) across India.
A key differentiator for Coulomb Litech has been its focus on building core technology in-house. The company has developed its entire battery stack — encompassing hardware, software, and proprietary algorithms — internally. This includes Battery Management Systems (BMS), liquid cooling architectures, CCS charging interfaces, and IoT-enabled analytics platforms that collectively support rapid charging while extending battery life.
The newly secured funds will be primarily allocated to establishing a state-of-the-art manufacturing facility in Navi Mumbai, enabling Coulomb to scale production and reduce dependence on external suppliers. Beyond manufacturing, the capital will support expanded research and development efforts, pilot program scale-ups, and broader commercial collaborations with EV OEMs and fleet operators.
Looking ahead, Coulomb Litech aims to solidify its position as a strategic battery partner for enterprises transitioning to electric mobility, particularly in heavy and utility vehicle categories. With India pushing for greater electrification of its transportation and industrial sectors, the startup is positioning itself to play a significant role in supporting that transition with robust, high-performance battery solutions.
