Drone Battery Supplier in Kolkata & East India

Semi-Solid State Drone Batteries Supplied to Kolkata, West Bengal & Eastern India

Leolus Energy Private Limited supplies Nexfly semi-solid state drone batteries to Kolkata and across eastern India — including West Bengal, Odisha, Bihar, Jharkhand, and the North-East states. We deliver directly from our Bangalore manufacturing facility to drone operators, agriculture technology companies, surveillance UAV operators, and industrial drone fleets across the region.

East India Drone Battery Use Cases

Eastern India has rapidly developing drone applications — from the rice agriculture belt of West Bengal and Odisha to the logistics corridors of Kolkata, flood management in Bihar, and tea gardens in the North-East.

• Agriculture Spraying Drones: 6S and 12S Nexfly batteries for crop spraying and fertilizer application in West Bengal's rice belt, Odisha's paddy fields, and Bihar's agriculture zones. India's Kisan Drone programme is expanding adoption across the eastern states rapidly.
• Tea Garden Inspection & Monitoring: Battery-powered drones for health monitoring, pest detection, and mapping in Assam, Darjeeling, and the North-East tea-growing regions.
• Flood Monitoring & Disaster Response: Bihar and Assam are among India's most flood-prone states. Reliable, high-endurance drone batteries for emergency response, flood mapping, and relief coordination are in active demand.
• Logistics & Last-Mile Delivery: Kolkata's growing logistics drone corridor and North-East connectivity challenges make delivery drone batteries a growing market segment.
• Port & Industrial Inspection: Haldia Port, Kolkata Port, and the industrial corridors of Jharkhand require inspection drone batteries for routine infrastructure monitoring.
• Surveillance & Border Monitoring: Eastern India's borders with Bangladesh, Myanmar, and Nepal create active demand for long-endurance surveillance UAV batteries.

Nexfly Battery Range for East India

Why East India Drone Operators Choose Leolus Energy

• Semi-Solid State Technology: Nexfly delivers up to 350 Wh/kg energy density — significantly more flight time per charge than conventional LiPo or Li-ion batteries at the same weight. Longer flight time means more ground covered per sortie for agriculture and mapping operations.
• Monsoon Climate Performance: Semi-solid electrolyte chemistry does not swell or degrade in high humidity. This matters in West Bengal, Odisha, Bihar, and Assam where conventional LiPo batteries have a shorter practical life due to moisture exposure.
• 300–500 Cycle Life: Nexfly batteries deliver 300–500 cycles before capacity drops below 80% — 2–5x the life of conventional drone batteries. Drone operators running high-frequency spraying or surveillance operations benefit significantly from the lower replacement cost.
• Make in India — MSME Registered: 100% domestically manufactured at our Bangalore facility. Eligible for Kisan Drone subsidies and government procurement schemes. Relevant for agriculture drone operators accessing central and state subsidy programmes.
• Integrated BMS: Overcharge, over-discharge, thermal monitoring, cell balancing, and short-circuit protection in under 1ms. Critical for field operations in remote locations where battery failure is not easily serviced on-site.
• Custom OEM Configurations: We supply custom voltage, capacity, connector, and form factor configurations for drone OEMs and system integrators in East India.
