Real airtime depends on wind, throttle and camera load, so we don't print a hero number we can't defend. The arithmetic is the promise: you launch with four modules and 26.6Wh instead of one module and a shopping cart.

They're keyed to the FlipShot / GT3-class bay. The slot geometry is specific on purpose — a keyed contact can only seat one way, correctly. Flying a different frame? Check your bay against ref ZN-112558 first.

Each bay manages its module independently and the cells are CE-marked with printed energy ratings, not blank wraps. Standard lithium rules still apply: charge on a hard surface, don't run the dock overnight, and retire any module that swells or runs hot.

That failure mode comes from unbranded cells with no printed rating and no compliance marks. Every module here carries chemistry, capacity, watt-hours and CE/WEEE on the plate. Store at partial charge between sessions and they hold up.

At 6.66Wh a module you're nowhere near the 100Wh carry-on threshold most airlines enforce. Loose lithium goes in the cabin, never checked, and taping the contacts is a good habit. Confirm with your carrier — rules shift by route.

Orders leave the warehouse in 1–2 business days and arrive well inside the window shown at checkout — that date is the outside limit, not the estimate. Tracking lands the moment the label prints.

Thirty days. Not what you expected, send it back for a refund. We'd rather take a return than argue with someone who isn't flying it.
