From 2018 - 2023 I built custom electric cars. Now I am recording a series of videos for you where I explain the concepts I taught myself for you to learn faster than me.<p>People get confused by series & parallel battery configurations (including me when I started out), so this is my 7th video on basic EV concepts. Questions like the following I had, and others ask me now:<p>- How can I merge two battery packs?<p>- I want to add capacity, why can't I just put it in parallel when I need the extra capacity like a range extender<p>- ...<p>It seems intuitive but isn't always.<p>I also made a little widget where you can move the sliders and see sample battery packs.<p>I hope this is worthwhile and easily digestible. I animate as much as I can to make the concepts clear to understand.<p>Let me know if this helps.
