I usually buy bms's from Amazon. But before now I've usually got in 3s or 4S BMS is which Amazon has a lot of. Now I'm looking for 6s and 7s bms's and the only ones found on Amazon are pretty bad. EBay has a bunch but of course they're all coming from China. I've looked all over and cannot find really any US based suppliers massage companies to buy BMS is, all sorts of battery accessories.

Can anyone recommend a good source of DIY battery accessories and building supplies

 

Nobody knows of any?

Looks like a low margin commodity business that US companies are uninterested in, just like television and radios.

I don't think the TS wants to build one -- I think he wants to buy one already made. There are very few (if any) consumer electronic products manufactured in the USA. Industrial Electronics has a few suppliers supported by a higher price structure for non-commodity products.

Yeah I'm looking to buy one. I don't mean manufactured in the USA I just mean USA retailers selling them. The only place I can seem to find any is Amazon and eBay. There has to be other suppliers

Why do you think this is the case? Electronics retailers of all stripes have been decimated in the last 20 years. You could try Fry's

or visit them if you live near on of the 34 locations in and around California.

I guess I would add to this that US Retailers of electronics have been decimated as well. I can think of at least five in Southeast Michigan where I used to live that no longer exist. There are very few in North Central Florida where I live now. People in other countries speak wistfully about being able to purchase things at a local store. I haven't purchased anything at a local electronics store in 25 years. I've been a licensed ham for 15 years and never purchased anything from a local store. They just don't exist, but they used to.
