I should have perused this thread^ earlier.
I am not sure exactly how much flex my future batteries will be subjected to.
My first battery was built rigid for a rigid enclosure and enough padding that the enclosure could flex around the stiff battery. But this was also for a stiff deck.
I am using that enclosure strapped to a super flexy deck now, and that stiff battery survived, but I feel much better with dual 14awg silicone wire between p groups on my newer pack
I am not very impressed with the copper braid I bought, and it is several degrees of overkill, but in an Eve 40pl 10s1p, which will be my next build, Ill just stick with silicone wire.
But can I flatten it and weld it instead of soldering it?
With copper’s much greater thermal conductivity, soldering Series connections likely introduces way more heat than desirable to cell than would the same dimensions of pure nickel in the folded over tab method, and soldering before welding introduces some more difficulty.
I wonder how the tinning on silicone jacketed wire affects conductivity. If each super fine strand is individually tinned, then would current be less apt to flow outside that strand to an adjacent strand?
I’ll experimemt with flattenening and welding silicone wire this evening.
