Batteries Were Boring. That Was a Feature. It's Gone.

A Regulatory Clock Is Ticking

Drone manufacturers have long treated batteries as an afterthought—a disposable commodity sourced from overseas. That assumption is now colliding with a hard deadline. The FCC's domestic end-product exemption expires on January 1, 2028, and defense procurement restrictions on major Chinese cell producers will bite even earlier. Since most drones in service today rely on Chinese cells, a pack redesign is no longer optional; it is inevitable.

Why Domestic Cells Keep Failing

At this year's Commercial UAV Expo, guest author Howard Alt, CEO of Micantis, surveyed the battery aisle and heard the same promise repeated: American cells are coming "next year." History suggests otherwise. A123, Britishvolt, KORE Power, Freyr, iM3NY, and Northvolt all raised capital and announced plants, yet none reached volume production. The bottleneck was never money—it was the scarcity of engineers who have actually guided a cell line to yield, a skill measured in years, not quarters.

Know Where the Difficulty Lies

Alt draws a sharp line between three tasks. Pack assembly is straightforward, needing little more than a bench and a couple of workers at typical drone volumes. Pack design is achievable, requiring months of electrical engineering rather than years of chemistry. Cell manufacturing, by contrast, is brutal: more than fifty process steps, micron-level tolerances, and a yield curve that no textbook can teach. Drone OEMs should design and own the pack but steer clear of making cells themselves.

Turn Compliance Into a Selling Point

Alt's advice is to select an allied cell already in production in Korea, Japan, or Taiwan, ideally from a supplier also building that cell in the US, then design the pack in-house and contract the assembly. Buyers should demand three answers: a production lot from a running line, confirmation that the same cell will be available in 2028, and the name of someone who has taken a line to yield before. By owning the drawing, qualification record, and BMS data, a company can transform the battery from a regulatory burden into a marketable feature—complete with visible state of health, longer cycle life, and a second qualified cell in the same footprint.
