Why Li-ion

Lithium-Ion in FPV

New high-discharge cell technology is closing the traditional performance gap between Li-ion and LiPo. Combined with Li-ion's superior energy density, these cells deliver dramatically longer flight times while maintaining flight performance.

THE LAB

Where ideas get tested.

“This is where a lot of our ideas either prove themselves or fall apart. We test motors, batteries, frames, electronics, and whatever else we’re experimenting with.”
