Coulomb Litech Secures ₹20 Crore to Scale its EV Battery Operations

Coulomb Litech, a Mumbai-based battery technology startup, has raised ₹20 crore in seed funding to scale its manufacturing capabilities and expand its presence in India’s electric vehicle ecosystem.

Founded in 2020 by IIT Kanpur alumni Ameya Sathe and Darshil Dharod, Coulomb Litech focuses on developing fast-charging, long-life battery systems for medium and heavy electric vehicles. The company builds battery solutions for applications including material handling equipment, electric tractors, construction equipment, electric three-wheelers (E-3Ws), and energy storage systems.

Coulomb’s battery systems operate across a wide voltage range of 51V to 700V, with capacities of up to 80 kWh. These systems are already deployed in multiple commercial and pilot projects with OEMs across India. The company offers modular medium-voltage and high-voltage battery platforms designed to meet the operational demands of heavy-duty EV use cases.

A key strength of Coulomb Litech lies in its in-house technology development. The company has built its complete battery technology stack internally, including hardware, software, and algorithms.

Coulomb has developed in-house Battery Management Systems (BMS), liquid cooling systems, CCS charging systems, and IoT-enabled analytics platforms. This integrated approach enables fast charging while extending battery life—an essential requirement for commercial EV users.

The newly raised funds will be used to establish a state-of-the-art manufacturing facility in Navi Mumbai. Coulomb also plans to deploy the capital toward business expansion, research and development, and scaling ongoing pilot programs in heavy electric vehicle segments such as electric tractors, cranes, material handling equipment, and E-3W vehicles. In addition, the company aims to strengthen collaborations with OEM partners and fleet operators to accelerate the adoption of its battery solutions across commercial use cases. Coulomb Litech is also working to enhance product reliability, safety, and performance consistency under demanding operating conditions.

With a growing focus on localisation and manufacturing scale-up, the startup aims to support India’s broader push toward the electrification of medium and heavy electric vehicles. As adoption of electric mobility increases in commercial segments, Coulomb Litech seeks to strengthen its position as a trusted battery technology partner for OEMs looking to electrify heavy and utility vehicles in India.
