India’s electric vehicle (EV) sector is accelerating toward a greener future, but the heavy-duty segment—think electric tractors, cranes, and material handlers—has lagged behind due to battery limitations. Enter Coulomb Litech, a Mumbai-based startup that just raised ₹20 crore in seed funding to scale its cutting-edge battery technology. This infusion of capital signals strong investor confidence in homegrown solutions tailored for India’s demanding commercial EV applications.
The seed round, announced in late February 2026, will primarily fuel the construction of a state-of-the-art manufacturing facility in Navi Mumbai. Founders Ameya Sathe and Darshil Dharod, both IIT Kanpur alumni, plan to channel the funds into ramping up production capacity, advancing R&D, and expanding pilot deployments with original equipment manufacturers (OEMs) across the country.
Coulomb’s batteries are already proving their mettle in real-world tests, powering medium- and heavy-duty EVs in sectors like agriculture, logistics, and construction. With India’s government pushing for 30% EV penetration in commercial vehicles by 2030 under the FAME-III scheme, this timing couldn’t be better. The new plant aims to localize production, reduce import dependency, and meet the surging demand for robust, high-capacity packs.
What sets Coulomb Litech apart is its fully in-house developed technology stack—no off-the-shelf components here. Their battery systems span a versatile voltage range from 51V to 700V, with capacities scaling up to 80 kWh, making them ideal for heavy-duty use cases that demand endurance and quick turnaround.
Key innovations include:
This integration isn’t just buzzword bingo; it addresses the Achilles’ heel of Indian EVs: batteries that degrade fast under load. Coulomb’s packs promise longer life and faster charging, directly tackling total cost of ownership (TCO) concerns that have slowed commercial adoption.
India’s EV battery market is exploding, projected to hit $15 billion by 2030, but heavy-duty applications represent untapped potential. Passenger EVs dominate headlines, yet commercial vehicles account for 60% of fuel consumption and emissions. Diesel-dependent tractors and trucks guzzle 40 billion liters annually; electrifying them could save ₹2 lakh crore in import bills alone.
Challenges abound: inconsistent grid power, poor charging infra, and batteries ill-suited for dust, heat, and overloads. Global players like CATL and LG dominate two-wheelers, but local startups like Coulomb are carving niches in industrials. Their pilots with OEMs—deployed in material handling and agribusiness—demonstrate viability, with early data showing 20-30% better uptime than competitors.
Government tailwinds help: PLI schemes offer ₹18,100 crore for advanced cells, while state incentives in Maharashtra (Navi Mumbai’s home) sweeten the deal. Coulomb’s focus on “Make in India” aligns perfectly, positioning it as a key supplier in the ecosystem.
Ameya Sathe and Darshil Dharod founded Coulomb in 2020, fresh from IIT Kanpur’s rigorous labs. Frustrated by imported batteries’ shortcomings in Indian conditions, they bootstrapped prototypes blending hardware smarts with software algorithms. “We’re not just building batteries; we’re engineering the energy backbone for India’s heavy mobility shift,” Sathe has shared in interviews.
Their edge? Deep domain expertise—Sathe in electrochemistry, Dharod in systems engineering—paired with a lean team that iterates fast. From garage tinkering to OEM pilots, they’ve validated a model that prioritizes ruggedness over range anxiety. Investors, including family offices and EV-focused VCs, back this grit, seeing Coulomb as a scale-up story amid 150+ battery startups.
India’s heavy EV market could reach 1.5 million units by 2030, per NITI Aayog, driven by logistics (e.g., Flipkart’s e-fleets) and farming (PM-KUSUM solar integration). Coulomb targets high-margin niches: electric tractors for 15 million diesel units ripe for swap, and material handlers in warehouses booming post-COVID.
Rivals like Log9 Materials (energy-dense cells) and Exide (PLI-backed giga plants) focus broader, but few match Coulomb’s heavy-duty specialization. Globally, Proterra and Hexagon Purus eye India, but localization mandates favor locals. Coulomb’s IoT layer adds a SaaS-like revenue stream via analytics subscriptions.
Scaling isn’t straightforward. Raw material sourcing—lithium, cobalt—remains volatile, with India importing 90% despite domestic reserves. Supply chain snarls and BIS certifications could delay the Navi Mumbai plant. Competition intensifies as Tata and Reliance pour billions into gigafactories.
Talent crunch bites too: skilled battery engineers flock to EVs, but Coulomb must retain them. Regulatory flux, like evolving ARAI standards for heavy EVs, demands agility. Yet, their pilot traction (multiple OEM deployments) de-risks much of this.
Coulomb’s batteries aren’t theoretical. They’re live in pilot projects: e-tractors tilling fields without range woes, cranes lifting loads in sweltering factories, and E-3Ws zipping through urban chaos. One OEM partner reported 1,500+ cycles with minimal degradation, versus 800 for standard packs—translating to years of service.
For operators, this means capex savings (₹10-15 lakh per vehicle) and opex cuts via 40% faster charging. In ag-heavy states like Maharashtra and Punjab, it’s a game-changer for sustainable farming amid water-fuel crises.
Post-funding, expect:
By 2028, Coulomb eyes ₹500 crore revenue, powering 10% of India’s heavy EV batteries.
