I’m looking for some tinned copper flat bar I can use as busbars on a high discharge battery, are there any suppliers out there that sell part lengths? My searches all come up with suppliers offering a 4000mm length… which is more than I need to build a couple new batteries
Might bite the bullet or go getto and start searching scrap yards?
sounds overkill. i forget exactly but remember even .02" copper foil is much better than the nickel stuff typically used for connections. basiccopper.com is good for me and could maybe be cheap shipping
thanks Hummie i’ll check em out… I’ve got a 12s8p and a 8s12p I’m building, especially the latter will have some big amps. I’m really trying hard to build a battery with low internal resistance but also equal resistance across the p groups… the bus bars solve the problem of the latter
niobie i want to say is maybe his name, but he did comparisons of different materials and thicknesses on endless-sphere and its a classic guide that showed even pretty thin copper foil is really good. i forget all the numbers but maybe something with a bit of flex, like foil, is totally good enough for the amps.
