18650 battery pack 16s2p design (imgur.artemislena.eu)

This is a design I'm working on. The idea behind the wave pattern is so that they can be stacked without losing all too much space compared to rectangular cell packs.

I'm putting a 60C thermal fuse in between each cell pair. Should a cell overheat, the fuse will pop and render the pack useless. This is an additional safety feature on top of a BMS and periodic manual checkups with a thermal camera.

The idea behind all cells pointing upwards (positive facing up) is also a safety feature. Should one start to vent or catch fire the flames will go up immediately triggering an extinguisher above the cell pack.

Let me know what you think! I'm not finished with it yet but if you want the design files already let me know I'll send them to you.

Edited with a deshittified version of imgur.

Would like to see, but imgur is stalkerware bordering on malware. Sorry this comes across as negative digital neighbor friend. If at all possible, use your instance's pic rs host, a federated alternative, or other honest and straightforward host.

I know it is hard to care when doing electronics and all of the stalkerware nonsense in that space. I've got my own bedroom lab.

Yeah. I see what you mean. I find it acceptable for certain use cases like a quick showcase for stuff I want to share freely anyway.

It's a bad habit.
