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.

Ooh, a deshittified version of imgur? Or did you invent time travel?
