This case for Canon LP-E6 batteries works on a first in first out stack principle. It is a ridiculously simple way to make sure your batteries are cycled equally. Batteries from the charger slot in the top of the case, the next battery for use is pushed out the bottom.

To print as:

1. One colour no text: Print as is
2. Embossed: Break apart and delete letters
3. Two colours: break apart and assign colours

There may be some bridging issues on the back, just snip loose strands off.

This is an improvement on a similar design I did for LP-8 batteries

This version holds fewer batteries but three seemed a good number considering the amp hours they have.
