Artman Osmo Action 4/3 Battery 2-Pack with Dual USB Fast Charger Case Kit, 1800mAh Osmo Action Battery Compatible with DJI Osmo Action 3, Osmo Action 4 Sport Camera Accessories

Work great!

Both batteries were rejected by the camera as unusable...the charger seems to work fine, but the batteries are useless.

I'm slightly conflicted about this item. It seems to last as long as the regular battery - sometimes. On several occasions, after some use I get the message in the attached image - "the battery is abnormal, please retry". After that it has to be charged or a new one inserted.I'm not so much concerned whether the battery life is as good as the OEM - if it's shorter, fine - but what I don't like is surprises and a battery suddenly stopping working when I'm in the middle of shooting.So having found that out, I never rely on it. I use it when it's fresh, knowing I might have to change it to a new one before it indicates the charge is close to depleted.Then again, the price is reasonable and the charger is great. But I have to treat them as a "separate" battery system from the factory one.

Seems to hold as much power as the OEM. Will update if that changes.

I bought these as extra batteries for my Action Camera 4 right before a vacation and didn't have time to test them. I charged them and the first time I attempted to use one on my trip, my camera would turn on, but displayed a error message that battery wasn't compatible. The 2nd battery worked for one cycle, but then the camera gave the same error message for that battery. Now it's hit or miss if I can get the batteries to work in the camera. May be due to battery temp or something. By the time I got home from traveling it was past the normal 30 day return window.

good quality, seals good in the camera

The media could not be loaded. Purchased. Arrived quickly. Pulled items out and charged. Three box away and trash was taken to the curb. One of the few times I’ve done that. Went to use the next day and it doesn’t work. Attached is video. Battery fits. But Osmo 4 won’t record with the battery from this manufacturer. It turns on, but Osmo 4 will not allow recording.Can’t return because I was a moron and didn’t think about the timing of throwing the box away. Stuck watch batteries that do not work.

Love the case these batteries come with. It acts as the charging case. A much better value overall than their OEM counterparts. If you own an Acton 3/4 you should have some extra batteries on hand and this kit makes that easy.
