Most Indian drone manufacturers are forced to import batteries despite the development of the local industry. Currently, most Indian drones can only fly for 20–30 minutes, which requires operators to constantly replace spare batteries in the field.
Supply Chain Challenge
India has created a large drone manufacturing sector but has failed to build the necessary infrastructure for component production. The startup from Bengaluru, which produces such batteries domestically, was founded in 2021 by Kajal Shah, its CEO, and Dr. Saurabh Markandeya. Both founders previously had experience creating companies and worked in the mobility and clean energy sectors.
According to the company, the problem lies not with the drones themselves, but with the components used in them. This issue is particularly acute in agriculture, where spraying drones operate long shifts over open fields. Each battery change takes time, and every spare battery increases weight and costs for the operator.
Developing Batteries for Indian Conditions
Dreamfly develops and manufactures high-energy density battery packs for the aerospace, aviation, and drone industries. They work with various cell chemistries, including lithium, graphene, and supercapacitors. Engineering developments focus on ensuring safety and heat dissipation. Thanks to the thermal casing design, the operating temperature is reduced to 20 degrees Celsius, which decreases the risk of fire. Lighter cell stacks help reduce the overall drone weight.
Heat is a critical factor: a hot battery loses power faster, fails sooner, and carries an increased fire risk. In a drone, weight and heat are contradictory: a larger battery provides longer flight time but also increases mass and reduces payload.
Specialized Solutions and Clients
Dreamfly also creates batteries adapted to India's specific needs. One model is designed for high-altitude flights and functions at temperatures down to minus 30 degrees Celsius. Another is a non-explosive graphene battery developed specifically for agricultural drones that must be safe near crops and people.
The company sells its products not to end-users, but to drone and aerospace manufacturers. Among its clients are Tata Advanced Systems, the aerospace division of Tata Group, and Larsen & Toubro. Additionally, Dreamfly supplies components to General Aeronautics, which manufactures agricultural spraying drones, and Neosky India, a subsidiary of RattanIndia Enterprises. Large defense and engineering firms are slowly testing the components, and once a supplier meets these standards, it is difficult to replace them.
Funding and Prospects
In February 2025, the company raised 12 crore rupees in a seed round led by Avaana Capital with participation from Sunicon Ventures and existing investors. Previously, in 2023, it received 4.9 crore rupees in an angel round supported by Rebalance Angel Community. These funds will be used to establish a manufacturing facility, expand the team, and conduct further research. The company currently employs about 27 people.
Dreamfly representatives note that localizing battery production in India eliminates a common dependency in the sector: cells and packs are often imported by Indian drone manufacturers, making them vulnerable to price fluctuations and delivery delays. The company is also working on batteries for electric aviation and other aerospace applications, using similar engineering principles and requiring high certification standards. Experts predict rapid growth in the Indian drone market over the next decade, and Dreamfly believes that an indigenous component industry, starting with batteries, is necessary to support this growth.
