Product overview
The pack uses eight 65E cells in a 4S2P arrangement. It is the highest-capacity option documented in the CNHL 4S 21700 family, intended for aircraft efficient enough to benefit from a larger battery.
The XT90 version is positioned for larger endurance-focused fixed-wing aircraft, mapping and survey UAVs, and systems already standardized around XT90.
This energy-focused pack is not a substitute for a high-burst LiPo battery. Its usefulness depends on efficient propulsion, suitable current demand and an airframe capable of carrying the larger battery.
