Coulomb Litech Raises ₹20 Cr Seed Funding to Accelerate Advanced Battery Systems for Heavy EVs

Mumbai-based deep-tech startup Coulomb Litech has raised ₹20 crore in seed funding from a group of High Net-worth Individuals (HNIs). The fresh capital will be used to set up a new manufacturing facility in Navi Mumbai, strengthen research and development capabilities, and deepen original equipment manufacturer (OEM) partnerships across India’s fast-evolving electric mobility ecosystem.

Founded in 2020 by Ameya Sathe and Darshil Dharod, both alumni of IIT Kanpur, Coulomb Litech is focused on building fast-charging, long-life battery systems for medium and heavy electric vehicles. The company serves segments that are critical to India’s EV transition but often underserved by conventional battery solutions.

Coulomb Litech’s battery systems are designed for demanding commercial applications such as electric tractors, construction equipment, material handling vehicles, and electric three-wheelers (E-3Ws). Operating across a wide voltage range from 51V to 700V, with energy capacities of up to 80 kWh, the company’s solutions are built to deliver durability, safety, and high performance under harsh operating conditions.

Unlike passenger EV batteries, batteries for heavy-duty applications must withstand higher loads, longer operating hours, and faster charging cycles. Coulomb Litech addresses these challenges through in-house battery pack design, advanced thermal management, and intelligent battery management systems (BMS), enabling longer lifecycle performance and reduced total cost of ownership for fleet operators and OEMs.

The startup’s battery systems are already deployed across multiple commercial deployments and pilot projects in India, validating the technology in real-world use cases. With demand for electrification rising across agriculture, logistics, construction, and intra-city mobility, Coulomb Litech is positioning itself as a key enabler of India’s commercial EV infrastructure.

The upcoming manufacturing facility in Navi Mumbai will allow the company to scale production, improve supply chain resilience, and meet growing OEM demand with faster turnaround times. A portion of the funding will also be invested in next-generation battery chemistries, system optimization, and safety certifications aligned with global standards.

Commenting on the funding, the founders shared that India’s EV opportunity extends far beyond passenger vehicles. “Electrifying heavy-duty and commercial segments is essential for meaningful decarbonization. Our focus is on building battery systems that are purpose-built for these applications,” they said.

As India accelerates toward an electric future, Coulomb Litech is emerging as a critical player, powering the next generation of commercial and industrial EVs with robust, scalable battery technology.
