Battery Tech Startup Coulomb Litech Raises ₹20 Cr In Seed Funding

Coulomb Litech, a 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. This capital infusion is intended to help the company meet the growing demand for indigenous battery solutions in the commercial EV sector.

Founded in 2020 by IIT Kanpur alumni Ameya Sathe and Darshil Dharod, Coulomb Litech focuses on developing fast-charging and long-life battery systems for medium and heavy electric vehicles. The company specifically builds battery solutions for high-duty applications such as material handling equipment, electric tractors, construction equipment, electric three-wheelers (E-3W), and energy storage systems. By targeting these heavy-use segments, the startup addresses a critical gap in the market for batteries that can withstand rigorous industrial cycles.

Coulomb’s battery systems operate across a wide voltage range of 51V to 700V, with battery capacities reaching up to 80 kWh. These systems are already deployed in multiple commercial and pilot projects with several OEMs across India. The company offers modular, medium-voltage and high-voltage battery platforms, which are specifically designed to meet the heavy operational demands of industrial and heavy-duty EV use cases. These platforms allow for flexibility across different vehicle types while maintaining high performance standards.

A key strength of Coulomb Litech lies in its in-house technology development. The company has built its complete battery technology stack internally, including all Hardware, Software, and Algorithms. This self-reliant approach ensures that the technology is optimized for the specific environmental and operational conditions found in the Indian market.

Coulomb has developed in-house Battery Management Systems (BMS), Liquid Cooling Systems, CCS Charging systems, and IoT-enabled analytics systems. This integrated approach allows Coulomb to support fast charging while significantly extending battery life, which is an important requirement for commercial EV users looking to maximize their return on investment. The inclusion of IoT-enabled analytics also allows for real-time monitoring of battery health and performance across large fleets.

The newly raised funds will be used to set up a state-of-the-art manufacturing facility in Navi Mumbai. This facility will enable the company to increase its production capacity and maintain strict quality control over its products. Coulomb also plans to deploy the capital toward business expansion, further research and development, and the scaling of 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 its collaborations with OEM partners and fleet operators to accelerate the adoption of its battery solutions across various commercial use cases. Coulomb Litech is also working on enhancing product reliability, safety, and performance consistency under demanding operating conditions. With a growing focus on localisation and manufacturing scale-up, the startup plans to support India’s broader push toward the electrification of medium and heavy electric vehicles.

With the growing adoption of electric mobility in commercial segments, Coulomb Litech aims to strengthen its position as a primary battery technology partner for OEMs looking to electrify heavy and utility vehicles in India. By focusing on the technology stack and manufacturing scale, the company is positioning itself to be a long-term player in the transition to sustainable industrial transport.
