Coulomb Litech Raises ₹20 Crore in Seed Funding to Accelerate Heavy-Duty EV Battery Innovation
Introduction
India’s electric mobility revolution is expanding beyond passenger vehicles into commercial and industrial segments, where reliable battery technology is critical for large-scale adoption. Medium and heavy electric vehicles — including tractors, construction machinery, and logistics equipment — demand high-performance batteries capable of fast charging, long operational life, and consistent performance under tough conditions. One emerging player addressing this challenge is Coulomb Litech, a Mumbai-based startup developing advanced battery systems tailored for heavy-duty EV applications. The company has now secured fresh capital to scale manufacturing and strengthen its presence across India’s rapidly growing EV ecosystem.
About the Funding
Coulomb Litech has raised ₹20 crore in a seed funding round from high-net-worth individuals (HNIs). The investment reflects increasing confidence in indigenous battery technology companies that can support India’s transition toward electrified transportation and energy systems. As commercial fleet electrification accelerates, startups capable of delivering durable, high-capacity battery solutions are attracting early-stage capital. This funding will help Coulomb Litech move from pilot deployments to scaled production and broader market adoption.
Use of Funds
The newly raised capital will primarily be used to establish a state-of-the-art manufacturing facility in Navi Mumbai. The company also plans to deploy funds toward business expansion, research and development, and scaling ongoing pilot programs across heavy electric vehicle segments. Additional investments will support working capital needs and strengthen collaborations with OEM partners and fleet operators. By increasing manufacturing capacity and improving product reliability, Coulomb Litech aims to accelerate the commercialization of its battery solutions across industrial and commercial use cases.
About the Startup
Founded in 2020, Coulomb Litech focuses on designing and manufacturing fast-charging, long-life battery systems specifically for medium and heavy electric vehicles. Unlike consumer EV batteries, which prioritize compact size and passenger comfort, commercial EV batteries must withstand intensive usage cycles, heavy loads, and challenging environmental conditions.
The startup develops battery solutions for applications such as material handling equipment, electric tractors, construction machinery, cranes, electric three-wheelers (E-3W), and stationary energy storage systems. These segments represent a massive opportunity, as industries seek cleaner alternatives to diesel-powered machinery while maintaining operational efficiency.
How It Started and the Founders
Coulomb Litech was founded by Ameya Sathe and Darshil Dharod, both alumni of IIT Kanpur. The founders identified a major gap in the availability of robust battery solutions for heavy-duty electric mobility in India. While passenger EV adoption was gaining momentum, commercial vehicles faced limitations due to insufficient battery performance, long charging times, and durability concerns.
With a strong engineering background, the founders set out to build a fully integrated battery technology platform developed entirely in-house, enabling greater control over performance, safety, and cost.
Technology and Market Opportunity
Coulomb Litech’s battery systems operate across a wide voltage range of 51V to 700V, with capacities reaching up to 80 kWh. This flexibility allows the company to serve diverse applications, from smaller utility vehicles to large industrial equipment. Its modular battery platforms — spanning medium-voltage and high-voltage systems — are designed to meet the demanding operational requirements of commercial EVs.
A key differentiator for the startup is its vertically integrated technology stack. Coulomb Litech has developed its hardware, software, and algorithms internally, including Battery Management Systems (BMS), liquid cooling solutions, CCS fast-charging systems, and IoT-enabled analytics platforms. This integrated approach supports rapid charging while extending battery lifespan — a crucial factor for fleet operators seeking lower total cost of ownership.
The market opportunity is substantial. As governments and industries push toward decarbonization, electrification of logistics, agriculture, construction, and public transport is expected to accelerate. Reliable battery partners will play a central role in enabling this transition.
Business Model and Revenue Streams
Coulomb Litech operates primarily as a B2B technology supplier to OEMs, fleet operators, and industrial equipment manufacturers. Revenue is generated through the sale of battery systems, integrated power solutions, and associated software services. The company is already engaged in multiple commercial deployments and pilot projects with OEM partners across India.
In addition to direct product sales, the startup may benefit from long-term supply agreements, maintenance contracts, and data-driven services enabled by its IoT analytics platform. This diversified revenue approach can help create stable recurring income as adoption scales.
Future Plans
Looking ahead, Coulomb Litech aims to significantly expand manufacturing capacity, strengthen OEM partnerships, and scale deployments across heavy electric vehicle categories. The company is also focused on enhancing product reliability, safety, and performance consistency under demanding operating conditions.
Localization of battery manufacturing is another key priority, aligning with India’s broader push for domestic production and reduced import dependence. By building a robust supply chain and expanding production capabilities, Coulomb Litech seeks to become a leading battery technology partner for commercial electrification in India and potentially global markets.
Conclusion
Coulomb Litech’s ₹20 crore seed funding marks an important milestone in its journey to power the next phase of India’s electric mobility transformation. With strong in-house technology, a focus on heavy-duty applications, and growing partnerships with OEMs, the startup is well positioned to address one of the biggest bottlenecks in commercial EV adoption — reliable, high-performance batteries. As industries transition toward cleaner energy solutions, companies like Coulomb Litech could play a pivotal role in enabling sustainable, large-scale electrification.
