EV Battery Manufacturing Business India’s electric vehicle (EV) journey has taken a clear leap forward from policy intent to industrial execution on a large scale. With increasing adoption of EVs in the mobility and logistics sectors and renewable energy storage, the Union Budget 2026 has made a much-needed structural reform: the relief on customs duty on lithium-ion battery cells.
This one policy intervention significantly changes the economics of EV manufacturing and energy storage projects and is especially relevant to MSME startups, first-generation industrial entrepreneurs, and investors involved in preparing Detailed Project Reports (DPRs).
Lithium-ion batteries are the most costly and technologically important component of electric vehicles and energy storage systems. By easing the entry barriers through reduction in import duties on battery cells, the government has effectively helped to improve margins and speed up the breakeven timelines of the domestic manufacturers.
This blog discusses why lithium-ion battery manufacturing and assembly is becoming one of the best start-up opportunities in India, how the customs duty relief is enhancing the EV ecosystem and which business models are feasible at the MSME level.

India’s EV Market and the Lithium-Ion Battery Opportunity
India is now one of the fastest growing EV markets in the world. Demand is growing for two-wheelers, passenger vehicles, e-rickshaws, electric buses, last mile delivery fleets and stationary energy storage systems. At the center of this growth is one essential ingredient: lithium-ion batteries.
Despite growing domestic demand, India currently imports 75-80% of lithium ion battery cells, principally from China, South Korea and Japan. Battery packs make up 35 – 45% of the total cost of an electric vehicle, making them the biggest cost bottleneck of EV manufacturing.
Key Industry Estimates
Parameter | Current Estimate |
India EV Market Size (Projected) | ₹4.5 Lakh Crore |
Lithium-Ion Battery Demand by 2030 | ~260 GWh |
Import Dependency on Battery Cells | 75%–80% |
Battery Cost Share in EV | 35%–45% |
Battery Manufacturing Opportunity | ₹2 Lakh Crore |
The customs duty relief announced in Union Budget 2026 is expected to make costs of battery packs up to 8% – 12% down in the domestic market, making domestic assembly and integration of a battery pack a lot more competitive.
Why Customs Duty Relief is a Game Changer for EV Startups
Until recently, high import duties on lithium-ion cells limited the production of battery cells to big companies with deep pockets and scale advantages. MSME startups found it difficult to make viable margins as they had to purchase raw materials at high costs.
With the revised hierarchy of duties:
- Battery pack assembly is made viable at MSME scale
- In addition, local battery integration projects have higher gross margins
- BMS manufacturing becomes cost-competitive
- CAPEX required for EV retrofitting and battery swapping business
- Solar and renewable energy storage projects are financially attractive
For entrepreneurs and consultants preparing techno-economic feasibility reports, this policy reform has a direct positive impact on Internal Rate of Return (IRR), Net Present Value (NPV) and payback periods which makes the projects more bankable for financial institutions.(EV Battery Manufacturing Business)
