heads up: you need a special fire extinguisher for lithium. also its probably best just to put it outside and let it burn itself out; lithium battery fires tend to quickly consume the oxygen in a room.
@JamesBiggar10 ай бұрын
For sure, let it burn itself out (cue the fire proof container). I mean a fire extinguisher in case the battery fire starts another fire. I don't think folks want to let their homes or workshops burn themselves out lol.

All I can say is...HOLY CRAP. James, I have been a long time subscriber of your channel, I love your attention to detail and engineering that you put into your projects. You really should bring some of your builds to SEMA or something here in the States. I would love to see your work in person. Thanks for making these great videos.

Great video, I really like that you go deep into detail as making lithium batteries is not simples at all. I am curious about that amount of current going through the terminal bolts and not directly to the busbar, checking with a thermal camera when you have it working would be really nice. Keep it up
@JamesBiggar9 ай бұрын
Thanks! Your videos are pretty good too. Good point about the terminal. M10 brass bolt should handle up to 200A ok, I'll only be using around 160-180 most of the time. But I think stainless needs 40% more cross sectional area, so around M12 to handle the continuous current. I'm pushing it. I'll probably add some copper or brass washers to space between the busbars and cable lugs to take some of the load off the terminals.
@Asvybre9 ай бұрын
You'll probably be fine but try to check the temperature with the design as is and if need be add some copper or brass washers. I'm eager to see a test drive! @@JamesBiggar

I've been paying attention since the beginning, and I love the style you've gone with this build. Combining 3d printing with other materials. I'm using this concept in my next conversion (a much smaller moped, only a 25 pound 2kwh battery). I'm very much looking forward to seeing how you're going to mount and fasten the 2 battery cases into the frame of your bike, because I'm trying to figure that out now. Any hints?
@spokehedz9 ай бұрын
I'm sure this is not worth the re-print but you could put the polarity/voltage you are expecting out of the terminals into the plastic of the box.
@priteshzade5739 ай бұрын
The attention to detail is amazing. I am eagerly waiting for rest of the build. You are an inspiration. I still can't believe so much power in 5.7kwh.

is the clear epoxy on the bus bar screws better than a threadlocker?
@JamesBiggar9 ай бұрын
If you don't have conductive threadlocker on hand. Otherwise, conventional threadlocker would insulate the connection.

Can i ask why we need to clean the cell left over nickel strip?? Since we oso going to weid a new nickel strip on top??
@JamesBiggar2 ай бұрын
The og welds were weak and covered in epoxy. Epoxy needs to be removed to layer over top. easier to take the entire strio off with the epoxy and start from scratch than to spend the same time scraping epoxy with a risk of connectivity issues. If the nickel is clean and in good condition, then you can weld more layers over the old strips.

@ionclaw73409 ай бұрын
Did you test all the batteries individually?
@JamesBiggar9 ай бұрын
Yes, individually and in p groups. Always test every cell, especially if they're used, and after connecting them into p groups - this effectively turns multiple cells into one large cell. Each p group should have the same capacity. If they don't then one or more cells are lacking or have a very different IR than the rest and needs to be addressed. That's why it's best to check and match individually before assembling the p groups, then double check after assembly.
