Since I received my BMPCC(which I love), I’ve been frustrated with the lack of affordable power options that would work on extended shoots. So I decided to build my own. The project uses off-the-shelf parts and isn’t extremely difficult to put together. Some simple knowledge of soldering, drilling holes, and generally fitting things inside a box are needed. Other than that, it’s definitely in the realm of most DIYers like myself. I’m not an electronics expert, but I consulted some friends and family who are and ended up with a pretty affordable and awesome solution. And it’s not just for the BMPCC. This could be used with pretty much any camera rig.
You can see here it works with the battery box I built as well as commonly found commercial battery belts:
