So for the battery, we are actually using a modified version of an older Samsung battery (not the Note 7 haha).
That's something that we didn't want to reinvent. So we are working with a factory who has made these batteries in the past.
I didn't include more about the battery in this post. Is that something you'd enjoy reading more about?
I also wrote up a basic, but goofy, post on "What is a battery": https://cobattery.com/blog/what-is-a-battery

They simply need to design around a battery type - preferably one that is cheap and accessible - and let the user go from there. Maybe have the first one included, in which case the deal is just in volume discounts.
I think that's actually a key part of what makes CoBattery special. The case is designed for battery swapping and when you buy CoBattery you have everything you need to start swapping.
Also, get UL certified, or you're wasting your time.
