Rail-ready add-on

Your pack, our geometry

Supplemental bracket for a standard 6S LiPo

The female rail interface and battery pack are proprietary (patent pending) — we do not publish female-rail geometry, enclosure CAD, weld maps, or cell sourcing docs. The male rail on the airframe is open. That keeps safety liability and field performance where they belong: on a pack we control end-to-end.

If you would rather run a conventional hardcase LiPo on the same rail, use the supplemental bracket: it adapts standard packs to the Replicant rail interface. Grab a printable STL for your own printer farm, or buy a printed bracket from the store — no obligation to buy our battery.

OEM, fleet, or volume? Commercial programs — licensing, pricing tiers, and integration help.

Teams & OEMs

Volume pricing, licensing & custom integration

If you are scaling production, need cells integrated into your program, or want a custom rail-mounted solution, talk to us first. Reverse-engineering the pack or routing around the official path costs more in time, liability, and rework than most teams expect — and we would rather ship with you than against you.

• Volume discounting — structured programs for repeat and high-quantity orders.
• Battery licensing — straightforward, affordable terms where OEM use of our pack design makes sense for your product line.
• Design & integration services — we help you implement Replicant-class power and mounting without guessing rail geometry, thermal paths, or certification edge cases alone.

Why It Matters

The battery isn't just a power source — it's a structural component. Its mass damps vibrations for cleaner footage. The rigid construction stabilizes flight dynamics. And the rail system lets you swap batteries in seconds, not minutes.

The female rail interface and battery pack are proprietary (patent pending). The male rail and mount on the airframe are open under CERN-OHL-W-2.0. The pack uses spot-welded Molicel P45B cells and proprietary power management. We don't release pack or female-rail files — improper cell handling is a fire and injury risk, and those interfaces are the subject of pending patent applications. No licence under those rights is granted by the publication of the airframe files.
