Nexfly Series — Solid-State Drone Batteries
Get an Instant Drone Battery QuoteThe Nexfly Series is our flagship range of semi-solid state drone batteries, designed specifically for professional UAV operations. We built these batteries because drone manufacturers kept telling us the same thing: existing lithium-ion and LiPo batteries weren’t cutting it for commercial flight. They wanted higher energy density without the weight penalty, longer cycle life without the safety trade-offs, and batteries that hold up after hundreds of charge cycles — not just the first twenty.
In real-world testing with drone manufacturers across India, the Nexfly batteries deliver stable power output from takeoff through landing. The solid-state electrolyte architecture means significantly lower thermal risk compared to traditional LiPo packs, which matters when you’re operating in Indian summer conditions or running continuous surveillance missions.
We offer the Nexfly in 4S, 6S, and 12S configurations ranging from 11,500mAh to 40,000mAh. If your UAV platform needs a specific voltage, capacity, or form factor, we can custom-engineer a battery pack to match your exact flight requirements. We work directly with drone manufacturers building agricultural spraying drones, surveillance UAVs, mapping platforms, and delivery systems.

An Indian Alternative to Imported Drone Batteries
Most professional UAV teams in India still fly on imported LiPo packs — typically Tattu or Herewin batteries shipped in from overseas. They work, but the hidden costs add up: long lead times, customs clearance, currency-driven price swings, and almost no local technical support when something goes wrong on a deployment. As an Indian drone battery manufacturer, Leolus Energy offers a domestic alternative to these imported packs, built with semi-solid state technology that improves on conventional LiPo on the metrics that matter for commercial flight.
If you are searching for a Tattu alternative in India or a Herewin alternative for your fleet, the Nexfly Series is engineered to match or exceed imported LiPo on energy density and thermal safety while removing the import dependency. You order in rupees, get batteries in days rather than weeks, and reach an engineering team in your own timezone for sizing, custom packs, and after-sales support.
Imported LiPo vs Nexfly Semi-Solid State
| Factor | Imported LiPo (Tattu / Herewin) | Nexfly (Leolus Energy, India) |
|---|---|---|
| Energy density | Conventional LiPo | Semi-solid state, up to ~350 Wh/kg |
| Thermal safety | Higher thermal runaway risk | Solid-state electrolyte — lower thermal risk |
| Lead time | Weeks (import + customs) | Days — dispatched from Bangalore |
| Pricing | USD + import duty + forex risk | Factory-direct INR pricing |
| Support | Limited / overseas | Local engineering team in India |
| PLI / Make in India | Imported — no value-addition | MSME, 100% made in India |
For drone OEMs claiming PLI scheme benefits, sourcing batteries from an Indian MSME manufacturer contributes directly to your domestic value-addition. Read our full Tattu & Herewin alternative comparison →
