Hello
for my need, i create universal battery holder for my old 18650 Li-ion cell. This holder is not weight or volume efficient. It will serve more as a static backup source. However, it offers a universal connection option. It provides the possibility of serial and parallel connection or a combination of both. There is no need to solder or spot weld anything. Just wire as needed. The holders can be connected to each other using ziptie. No screws needed. In this way, you can create a large capacity battery storage. I have plan create expansion module for electronics board (balancer, powerbank etc.)

This model is a new version with some improvements. In the future, I plan to expand with new elements.

The holders are designed
