EV Battery Tech Extends Ukraine Drone Range by 46%

A Ukrainian company called PAWELL has figured out how to take battery cells designed for electric vehicles and stuff them into fixed-wing drones. The result: operational range jumped from roughly 19 miles to 122 miles on a single charge, as Euro Maidan Press reports.

One of those upgraded drones has already destroyed a Russian Buk-M1 air defense system worth an estimated $10 million, and another struck an ammunition depot deep behind enemy lines.

From Farms to Frontlines

PAWELL, based in Lviv, started by adapting drones that originally served in the agricultural sector. The company’s engineers swapped out standard lithium polymer batteries for LiNMC cells, the same battery chemistry used in electric vehicles from manufacturers like Tesla and Mercedes.

The physics behind the switch are straightforward. Traditional LiPo batteries used in most drones store roughly 150 to 170 watt-hours per kilogram. LiNMC cells push that to 230 to 260 watt-hours per kilogram at comparable weights.

That energy density advantage translates directly into range. More stored energy at the same weight means the drone flies farther or carries a heavier payload, or both.

PAWELL co-founder Pavlo Esyp told The New Voice of Ukraine that no universal battery solution exists for all drones. Each platform requires its own balance of weight, power output, and capacity depending on the mission.

Reconnaissance relay drones prioritize endurance. Strike drones need the range to carry warheads deep and come back. FPV drones need lightweight punch for maneuverability. PAWELL’s engineers tailor each battery configuration to the specific airframe.

The Buk-M1 Kill

The first confirmed combat result came in July 2025 on the Sumy direction. A PAWELL-equipped drone flew roughly 25 miles into Russian-held territory, located a Buk-M1 surface-to-air missile system, and transmitted its coordinates back to Ukrainian artillery. The guns did the rest.

The Buk-M1 (NATO designation SA-11 Gadfly) is a self-propelled, medium-range SAM system that entered Russian service in 1983. It carries four 9M38 missiles and can engage aircraft, cruise missiles, and helicopters at ranges up to roughly 20 miles.

A standard Buk battalion includes a command vehicle, target acquisition radar, six launcher vehicles, and three reload vehicles. Destroying one isn’t just removing a launcher from the battlefield. It’s punching a hole in the layered air defense network that protects Russian ground forces.

The estimated value of a single Buk-M1 system sits around $10 million. The drone that found it cost a fraction of that. The artillery rounds that killed it cost even less.

122 Miles and Back

PAWELL pushed the range further in October 2025. A Postman-type fixed-wing drone flew 122 miles on the southern direction carrying a 33-pound warhead. It struck an ammunition depot and returned to Ukrainian lines with roughly 10% battery remaining, enough for another 12 to 15 miles of flight if needed.

That 122-mile mission matters because the same Postman drone, running on its standard manufacturer battery, maxes out at about 84 miles. The PAWELL system extended its operational reach by more than 46%. For context, that’s the difference between hitting targets just behind the contact line and reaching deep into Russian logistics infrastructure.

PAWELL says the next development milestone is exceeding 249 miles of range. If the company hits that number, Ukrainian fixed-wing drones running on modified EV batteries would be capable of reaching targets that currently require much larger and more expensive platforms to engage.

DroneXL’s Take

The part that doesn’t make the headline: this isn’t just a battery upgrade. It’s a supply chain hack.

LiNMC cells are mass-produced for the electric vehicle industry. They’re commercially available, competitively priced, and manufactured at a scale that military-specific battery production can’t touch. PAWELL didn’t invent a new chemistry.

They took cells that roll off EV production lines by the millions and engineered them into drone-compatible packs tailored to specific airframes. That’s a procurement advantage disguised as a technology story.

The cost-per-engagement math here is brutal for Russia. A modified agricultural drone carrying an EV battery pack found and helped destroy a $10 million air defense system.

A Postman drone carrying a 33-pound warhead flew 122 miles to hit an ammunition depot and flew home. These aren’t expensive precision munitions. They’re relatively cheap platforms made dramatically more capable by a battery swap.

Ukraine’s drone industry keeps proving the same point over and over: when you can’t outspend your opponent, you out-engineer them with commercial technology adapted for the battlefield. PAWELL’s 249-mile target would put even more Russian rear-area assets at risk from platforms that cost less than a new pickup truck. The EV industry built these batteries to move cars. Ukraine is using them to reshape a war.
