Quick description: no spot weld or solder needed multiple holder can be connected together - just ziptie needed serial, paraler or both connection possible expansion module: for this time, just two powerbank module. Next module soon.

some bla bla: 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 for printing on a sla printer, I cannot guarantee functionality when printing on an extruder printer! I recommend using a more resistant resin - at least for screws due to better resistance to tightening.

if u like, u can tip me :D live long and prosper
