Well, remember the nice solid copper battery interconnects I hand-made? And how some people said I needed to use braided cable? Well, after doing Yet More Research, they were right. The problem is that batteries move – all the time – even if you have them strapped. Mine aren’t strapped. So if batteries move, and the interconnects don’t, the batteries eventually get damaged.
So, in an effort to build some new ones, I tried two techniques: wrapping copper plate around the cable, and crimping copper pipe to the cable. As you can see from picture, the pipe does a lot better job. The pipe crimps nicely to the cable, and doesn’t leave much sticking up (unlike the plate).
So – only 106 more connectors to build.
