Heard about #DonutLab yet? Me neither.

However, they released an amazing new #DonutMotor 2025 in multiple products and now they're releasing a new kind of #solidstatebattery #DonutBattery that may disrupt the whole market according to their promo video: https://www.youtube.com/watch?v=Y-aPS2AwMbc

- cheaper than #LiIon
- 50% weight or +100% capacity for same weight
- full charge in 5min
- no loss due to temperature
- more cycles than you will ever need
- no degradation over time due to fast #charging
- no problematic materials
- ...

You "donut believe"? Well, they want to prove their point soon: https://www.youtube.com/watch?v=uiOma6v_EZY

Now, they have my attention. 🍿

This look into 18650 cells is *very* interesting - not least because of the conversation about reliability of these particular cells, but the thought that I've probably got tens (if not hundreds) of rechargeable Li-Ion cells lying around the house (in devices, or in my "charge these" box), and at *some point* they're gonna break ...

I've been designing PCBs for a while, but this is my first time ever designing one with any sort of battery charging or antenna connection. I hope I managed to do a decent job, but if anyone has more experience with either and feels like taking a look at my PCB/schematic, it would be greatly appreciated!
