Almost all modern cameras use Lithium-Ion batteries. They're small, rechargeable, and quick to swap when one gets empty.

However, the problem with Li-ion batteries is the fact that with time, they start to degrade. A two-year-old battery will last much less than a new battery. Also, with smaller batteries their capacity out of the box isn't huge either, so one needs to have a few as a backup when doing longer shoots or going traveling.

But it can become quite a challenge to keep track of which batteries are charged and which ones are empty when you have a bunch of them, they all look the same and some are only half-working.

That's why I decided to make a quick and simple camera battery organizer. This project will focus on making a station for the Sony NP-FW50 batteries. But the same concept could be used with any camera brand, you'll just have to make your own 3D model.

I printed the base with white filament, to make it easier to see which slots are filled at a glance. The housing for the switch was printed in black to match the charger.

I made a short video about this project too:
