Also, get UL certified, or you're wasting your time.
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.
