endurance platform.
Two energy density tiers across multiple voltage platforms (6S, 12S, 14S, 18S) and capacities from 9.8 Ah to 72 Ah. All cells deliver 2–3C continuous discharge with 10C burst capability.
330 Wh/kg Ultra-High Energy
Industry-Leading DensityOur flagship endurance series — the highest gravimetric energy density we manufacture. Built for fixed-wing platforms, agricultural drones, and mission-critical surveying where every gram of battery extends flight time.

310 Wh/kg High Energy
Proven PerformanceThe endurance workhorse — slightly lower density than the 330 series, but proven across multi-rotor and fixed-wing platforms. Ideal when reliability and broad compatibility outweigh peak energy density.
