Thank you so much for sharing your experience. It's valuable.
Do you know any best practices about who does this right, and how it can be done both safely and economically? If necessary with automation and large scale.
- Syonyk 5y agoI really don't. I expect there are some people doing it, but I also expect they're not busy posting their stuff to YouTube. I learned what I learned with a lot of time spent in datasheets, PhD theses on lithium, and a background in electrical engineering that helped me make sense of the weird gaps. I'm no longer doing much with lithium beyond the occasional personal pack (which I still build to the same standards I built other packs to). The best advice I have is to learn all you can from reading things, not watching things. The bits and pieces of solar/battery/energy work I've seen on YouTube as people link them tend heavily sensational and "WOW I NEARLY BLEW MYSELF UP!!!! big O YouTube emotion face" and I've no interest in any of that. Also, you shouldn't assemble a pack with the batteries above about... oh, 3.5-3.6V/cell. Down there, there's typically not enough energy for the pack to get exciting if something does short. It'll get hot, it may vent a cell (again, do not breathe), but it probably won't have enough energy to enter a thermal runaway, which is something you want to avoid at all costs.
- Syonyk 5y agoFollowing up a few days later, someone did send a video my way that I agree with every aspect of - the guy does a very safe, competent build, with correct techniques, and builds a far better and safer pack than most of the commercial packs I've seen. https://www.youtube.com/watch?v=adY-S8AH_Jc https://www.youtube.com/watch?v=adY-S8AH_Jc
