This exposes the battery bay, MicroSD card reader and internals of the camera to the elements. The protective door of the camera needs to be removed. Running a cable into the camera poses another problem. This keeps the cable more flush with the helmet and in the side view of the camera, where there are blind-spots. It is perfect for this use as I can run the cable through the straps of the helmet. That said, I’d be very careful of branches when tree skiing. Here is the exact one I use if you’re wondering.Ġ.9m is about perfect for running it to a MAX mounted on a helmet, offering just enough slack to allow for lots of movement, whilst not being too long to risk getting easily caught on anything. I can zip the pocket almost shut to protect the battery from the weather, leaving it slightly unzipped to run the USC-A (from the Powercore) to USB-C (to the MAX) out. To further insulate it, I place it in a thick fleece pocket. The Trek Pack has a useful top pocket which perfectly fits the PowerCore and has room for an electronic hand warmer ( here’s the electronic one I use). In warm conditions, we can get about 2-2.5 hours out of a single GoPro battery in video mode, therefore, I should be able to easily use the PowerCore to shoot continuously for an entire day if I can keep it warm. So the PowerCore+ holds almost 17x more charge then the standard MAX battery. The advantage of using an external pack means not only can it be kept warm more easily, but also offers more power. We actually recommend using one with our Trek Pack for long hikes to reduce the reliance on expensive GoPro batteries. ![]() It is possible to use an external power source with the MAX. ![]() Using an External batter GoPro MAX Insulation I realised quite quickly, that for optimum conditions I would need to rely on an external battery power source that could be kept warm more easily. There is more area around the top, bottom, and sides of the camera, where there are blind spots, but it is not particularly effective to insulate solely in these areas. And the front of the camera is most exposed to the elements. As you can see above, there is only a small space on the front and back of the camera’s body before any jacket will impede the view (about 2mm). In very cold temperatures you could include heat warmers inside the jacket, on the back of the camera, to increase the internal temperature.Ī similar approach is not possible with the MAX. Various covers, like microphone wind protectors for HERO camera illustrate how thick the cover can be before it encroaches into the lenses field of view. The GoPro HERO camera bodies can be easily covered in an insulating jacket to protect it from the external conditions. The MAX poses some unique challenges when trying to keep the body insulated, and therefore the battery warm. So the way to ensure this doesn’t happen it to keep the battery warm. In very cold temperatures, this can result in the battery being not able to generate enough power and in these cases the camera won’t turn on at all. Hence, you’ll see the charge go down much faster than if you stayed inside. That means more of your battery’s power is wasted – so your battery has to work harder. As the temperature drops, the internal resistance of your battery goes up. Because of this, high temperatures for prolonged periods can actually shorten battery life, as the chemical reactions occur faster. The chemical reactions will increase and the battery may over-perform. That means the battery can’t generate as much power when compared to warmer temperatures. Since chemical reactions slow down in cold weather, chemical reactions don’t happen as quickly. Why batteries drain quickly cold weatherīatteries use a chemical reaction to make power. In a few weeks time I’ll be heading to the Alps to capture some ski footage (more on that to follow on the blog soon), so designing a setup that could be kept warm for a full day up the mountain was vital. The bad news? It’s currently only available for HERO10 and HERO9 action cameras. GoPro recently announced a new high-performance Enduro battery designed for cold temperatures. When trying to capture footage on a GoPro in the mountains during winter you might have seen this too, or even had issues getting the camera to even turn on. ![]() If you’ve ever tried using electronics in very cold weather you might have observed your battery draining quickly.
