   If you’re all about capturing life’s epic moments with your DJI Osmo Action 3 or 4, this FirstPower replacement battery set is about to become your new favorite gadget buddy. These batteries, with their impressive 1850mAh capacity, keep your camera running longer, which means more time to snap those perfect shots without having to constantly worry about power. And let’s talk about the dual fast-charging hub—charging two batteries at once? Yes, please! It’s a total game-changer, especially when you’re on the go or need to power up quickly between adventures.I was pleasantly surprised by how well these batteries fit into my Action 4—just like the original ones! No weird power drops, no difference in performance, just pure battery bliss. And the charger? It’s sleek, it’s slim, and it’s super easy to toss in your bag. I love the USB-C port because it feels like everything should be USB-C these days. Plus, the bonus of being able to charge the original DJI batteries is just the cherry on top!The only tiny hiccup is that the batteries need a bit of a firm push to snap securely into the charger. It’s nothing major, just something to get used to—think of it as a mini arm workout! But honestly, this small quirk is so minor compared to how well everything else works.All in all, this set is a fantastic pick for anyone looking to keep their camera powered up and ready to roll. Whether you’re a seasoned pro or just starting out with your DJI Osmo Action camera, these batteries and charger are reliable, convenient, and super easy to use. Happy shooting!

   Initially the non-DJI batteries would cause errors on the camera. But after I updated the camera firmware the warnings went away. They seem to have about the same runtime as DJI batteries. Very pleased.

   These batteries work with the DJI Osmo Action 5 Pro camera as well as being backwards compatible with the Action 4 and Action 3.The charger is nice. I have another charger that is “open” right above the bottom 25% of the battery, which I will most likely be using more often – currently, I am charging the batteries up in the supplied charger, but I had an issue with the GoPro batteries and a more closed up charger, and I just don’t want to have any issues with bulging batteries or such.These are great batteries, and they work across a range of cameras.Other companies who make Action Cameras and such ought to pay attention.Five Stars!
