Let's talk batteries! - BUILD OR BUY?

Oh I know all the right things to do. I’m just better at doing the not so great way. :joy:But .15 is what I had. And I doubled it, and then tripped it on the connections between groups. But next pack im doing with copper.

Pure copper corrodes when left to the open air. But you knew that already.

I tried some plain copper lugs on my 3s 10ah lifepo4 battery and got some rather high resistance thru the main discharge leads. Switched to tinned copper and got a much lower resistance value.

Are there any copper battery strips that are tinned?

I’ve been looking. But I’ll post pics of what I made. I was doing some copper accent pieces on a huge house a couple years ago. I assumed it was just going to be plated tin or paint, nope it was real, really real, and $$$$. Gotta treat it once a year or so. Nice stuff.

Does anyone know a place in the UK to purchase pre made battery packs? Looking for 10S2P, 10S3P, 10S4P, 10S5P or 10S6P.

Import Duty is a killer to buy from the USA or other locations.
