A 3 hour battery for the GoPro Hero 12? TESTED!

Yes, you read that right. For those of you who want/need longer shooting times from your camera, this may be the battery that solves all your issues!

Presenting the Fitstill Extended GoPro Battery.

If you want to shoot for 3hrs in 5.3K 30FPS, here’s your solution!

So what is it and more importantly, does it work?

Here’s what it is!

The Fitstill extended battery pack for the GoPro camera is an extended battery that fits inside and around your GoPro camera. This is somewhat reminiscent of the types of extended batteries that you would see for professional DSRL or mirror-less cameras but scaled down for the GoPro Hero line of the cameras.

The design is pretty unique as it almost looks like part of the battery pack actually fits inside the camera (which it does) but it actually doesn’t use the battery contacts to power the camera. Instead, it actually connects to the USB-C port of the camera to provide power. The part that fits inside the battery chamber more or less acts as a guide to line up the USB-Port properly to avoid damage. So that’s actually a pretty smart design. This also means you still have full access to the touchscreen of the camera as the battery doesn’t block it in any way.

You can see the USB-C connection in this picture.

So does it work?

Well, this is where it gets interesting.

According to the Amazon Page, this product is designed for the Hero 10 camera, in fact, the wording specifically states “Only for Hero 10 black”.

Not my imagination, it clearly states “Only for GoPro Hero 10 Black”

However, when the product arrived, it clearly said on the Box “For the Hero 9 and Hero 10 camera”. Now I’m going to hazard a guess that this product (and packaging) was created before the Hero 11 and Hero 12 were released. So since fortune favors the bold (and the foolish alike) I decided to test this battery pack with the Hero 10, Hero 11 and Hero 12. The results were interesting. ( I recently gave away my Hero 9 to my brother in Florida).

Now please note, that all 3 cameras were running the GoPro Labs firmware and that the power checking requirements had been bypassed using the TUSB=1 command.

With the Hero 10…… the battery pack simply didn’t work. It did nothing. Nada. Zilch! I couldn’t get the camera to even show a sign of life. I thought that maybe I had damaged the USB-C port, but after attaching the camera to the media mod (and successfully detecting it) and connecting the camera directly to USB power (which worked) it seems there may be a compatibility issue. Maybe. It’s also possible that the USB-C port of the camera is damaged, but it’s odd that the media mod and external power still worked. So, Hero 10 owners beware!

With the Hero 11, when the battery pack was attached… there were no issues! The camera powered right up and stayed turned on. I even filmed a few clips without any issues whatsoever.

With the Hero 12, the camera also powered up and recorded. However at one stage the rear display didn’t work properly, but a simple reboot seemed to fix that issue. Odd, but a temporary issues.

I then decided to put the battery pack through its paces. So I set the Hero 12 up to record in 5.3K 30FPS and the results were…….. actually pretty impressive.

Please note the Hero 12 in all its glory filming away. I also included the Portland Oregon weather report!

I managed to shoot in this resolution and frame rate for nearly 3 hours! (about 2hrs 59 minutes if you want to be exact), so I was very impressed. Now since the camera was still and mounted on a tripod, I did have hypersmooth turned off (it wasn’t needed) and the bit rate set to standard (I simply didn’t need a high bitrate for this test). So, I would expect that 3 hours in 5.3K 30FPS was probably the most I would get out of the camera in these settings. I expect times will differ based upon resolution, frame rates and hypersmooth options.

Still, 3 hours……. color me impressed!


So all is good?

Well there are some issues to be fair.

A: This battery plugs into the USB-C port of the camera, if you use it, you’re not going to be able to connect a media mod or external mic to your camera (although with the Hero 12, you still have the option of using your bluetooth audio headset). So that’s unfortunate.

B: I wouldn’t classify the frame as particularly sturdy. It feels a bit cheap and flimsy. Remember, a chain is only as strong as it’s weakest link. This applies to the frame that this battery and camera sit in. Although it has a nice wide locking mechanism at the top, the clip is simply held in place by two tiny pieces of plastic. Should one of those snap or break, your camera could easily end up falling out of the frame. I really wouldn’t have minded paying $20 for a sturdy aluminum frame.

C: It’s not waterproof or weatherproof, nor does it claim to be. I’m not sure how hard it would have been to put a rubber gasket around the edges of this battery pack, but if Fitstill had put such a gasket in place, this would have been a fantastic extended battery pack.

D: For the price, I doubt that it is cold weather compatible. Usually cold weather batteries are a lot more expensive. Unfortunately I don’t feel like throwing this in a freezer to find out (I don’t have that type of budget) but pretty sure this is a summertime battery only.

E: It powers off after about a minute or so of nonuse. This is hardly surprising, in fact most USB power banks to the exact same to conserve battery life. This does however mean that the battery pack isn’t suitable for schedule capture where your camera spends long times powered off.


Taking into account all of the above, is it still worth a purchase?

I think it depends on your need. If you want to film for extended periods with your GoPro Hero 11 or 12, then yes, this is well worth looking into. Only if you don’t need to use the media mod or external audio however…….. and you don’t need it to be weather proof or work in cold weather. I don’t think I would trust it mounted on an airplane or a car though for fear of the hinges failing. Then again, I’ve dealt with this design problem before with 3rd party knock off protective cases using the simple cheap hack of wrapping a rubber band around the outside to stop the case from opening.

Either way, for me, I’m pretty sure this battery pack will prove to be plenty useful over the coming summer months.

Flight to Workman AirField. New DemonView Movie!

Flight to workman airpark.
Brand New DemonView Movie!

Ever wonder what it’s like to fly into an airfield? Well, no doubt you’ve watched the flight to Evergreen Airpark, this is the follow up where we flew to Workman Airfield OR41. So, in this movie, MerryMunks, Natasha Stenbock and I flew out to Workman Airpark in a Maule M5 180C. Weather wise it was a pretty nice day, warm temps but a bit of smog in the air from all the brush fires which were legal for that time of the year. Lots of things to see from the air in this flight and the Maule handled the flight with ease (thanks to the great pilot of course). It’s always a pleasure to the skies of Oregon and see such amazing sights. However, working in the back of the plane is sometimes a fulltime job. If you see me with my head down, it’s usually because I’m working the cameras or looking up information about our destination that the pilot and co-pilot need to know. So really hope that you enjoy the Flight to Workman Airpark video.
