The BCX204 covers 3 bodies, from the Osmo Action 3 to the Osmo Action 5 Pro; the most common buying mistake is not capacity but boundary cases such as Action 2 → magnetic cell. The table below lists every compatible body by series, followed by the models that take a different cell. Always trust the marking on the camera or in the battery compartment: similar-looking packs are not necessarily interchangeable, and Action 3 / 4 / 5 Pro should still be checked against the contacts and firmware of your body.
Key specifications and limits: 4K 60p 70–90 min / 1080p 150 min / 1080p 25fps 4 h. Actual figures vary with resolution, frame rate, screen brightness and ambient temperature, so plan spares around the shortest figure in the table.
Full compatibility list
All 3 bodies below accept the BCX204 or a cell from the same family, grouped by series. “Compatible” means the compartment and contacts match; it does not guarantee that older bodies can exploit the full capacity of a high-capacity pack.
| Body | Body | Body | Body |
|---|---|---|---|
| Osmo Action 3 | Osmo Action 4 | Osmo Action 5 Pro |
Which models do not fit
This is where search results most often mislead. Packs with similar names and near-identical shells frequently belong to entirely different systems, and forcing one in can damage the compartment.

How to check before ordering
The reliable check is the model printed on the bottom of the body or inside the battery compartment, matched against this list. On a used camera, also confirm that a previous owner has not swapped the battery door.
To pick by model, start with the specifications and stock status on DJI BCX204 1950mAh, then browse the full article set in BCX204; if your body belongs to a neighbouring system, DMW-BLK22 has the side-by-side explanation.
FAQ
How many bodies take the BCX204?
Our list contains 3 bodies, from the Osmo Action 3 to the Osmo Action 5 Pro. It is grouped by series, but still check the body marking, since a later generation in the same line can switch cells.
Is the BCX204 interchangeable with neighbouring models?
Action 3 / 4 / 5 Pro shares one shell and contact layout, so those cells fit each other. However, Action 2 → magnetic cell, and those bodies need their own cell — never judge by shape alone.
Will every body on the list benefit from higher capacity?
All of them run normally, but older bodies set their cutoff and fuel gauge to the original specification, so extra shots do not scale linearly and the percentage may read conservatively.
How do I confirm which cell to buy?
Read the model on the bottom plate or inside the battery compartment and match it against this list. If the marking includes a suffix or a “for use with” note, follow the manual rather than the capacity figure.
