Maximum power. Minimal weight.

Built for pilots who want the punch of a high-C battery without giving up the advantages of cylindrical Li-ion. Our 6S 4000mAh pack uses tabless Reliance RS-40 21700 cells engineered to deliver exceptional current capability and low voltage sag, keeping your drone responsive when you push the throttle.

At roughly 89Wh, this is our lightest and highest-power pack—ideal for aggressive long-range builds, high-performance 5–7" drones, and pilots who demand more from every amp.

Built for power. Built for speed. Built to fly.
