Molicel INR18650-M35A 3500mAh Li-Ion Cell

The Molicel INR18650-M35A is a high-energy-density lithium-ion cell designed to maximize flight time in sub-250g micro long-range FPV cruisers, fixed-wing UAVs, and radio transmitters. Striking an optimal balance between capacity and current delivery, it provides a genuine 3500mAh alongside a 10A continuous discharge rating. This makes it highly suited for custom 4S or 6S endurance packs where sustained low-amp draw takes priority over aggressive punch-outs.

Key features

• 10A maximum continuous discharge rating supports the steady current demands of efficient long-range powertrains.

• Authentic A-grade Molicel cell, ensuring tight internal resistance matching and consistent cycle life across custom packs.

• Unprotected flat-top terminal design ready for spot-welding with standard nickel strip.

• Direct drop-in compatibility for 18650 radio controller bays, including popular Radiomaster and Jumper transmitters.
