Vimana V25 18650 2500mAh 8C Li-Ion Cell

The Vimana V25 is a high-discharge 18650 Lithium-Ion cell tailored for custom FPV battery builds, radio transmitters, and goggle power banks. Delivering a 2500mAh capacity alongside an 8C continuous discharge rating, this cell comfortably pushes up to 20A of sustained current. This makes it highly suited for lightweight, low-amp-draw aircraft like sub-250g micro long-range drones, 4-inch cruisers, and fixed-wing builds where maximizing flight time is the primary goal over punch-out power.

Key features

• Standard 18650 form factor for assembling custom 2S, 4S, or 6S long-range Li-Ion packs.
• 8C discharge rating safely supplies up to 20A continuous current for sustained cruising.
• 2500mAh capacity offers significantly longer flight times than similarly sized LiPo equivalents on efficient builds.
• Excellent drop-in replacement cell for 18650-compatible RC transmitters and FPV goggle battery cases.

When spot-welding or building custom flight packs for multirotors, verify that your drone's peak amp draw remains within the 20A continuous limit. These cells excel in efficient cruising setups but are not intended for aggressive, high-throttle freestyle flying.
