cellmate said:Hi all,
I was wondering if there's any reason I should not weld a 2P battery pack in an "X" configuration, to avoid layering nickel strips and to reduce the amount of welds.
I made a separate post here about it with more detail, but it has only gotten one response so I hoped I might get a bit more feedback here.
Thanks! (and sorry for asking twice)

Interesting comment!flippy said:people are stupid. more is not better. its like gluing 2 bank cards togther and thinking you can pay twice as fast. :lol:
Cowardlyduck said:Interesting comment! I've had reasonable success stacking/layering 0.15 nickel. I regularly do 4 layers x 7 series rows for 100-120A discharge packs and they hold up fine and don't get hot. I understand layering is not the same as a single bus bar or thicker nickel, but with enough layers surely it can compensate for the less than ideal path? What I mean is....if 0.15x7mm standard nickel is capable of ~7A...2 layers is not 14A...probably more like 10. 3 layers might be 15A...with 4 being ~20A maybe. Either way...I generally way over-compensate when building packs this way and to-date have never had an issue layering nickel with over 15 packs built and sold to my customers, so I would love to hear why this might be an issue!flippy said:people are stupid. more is not better. its like gluing 2 bank cards togther and thinking you can pay twice as fast. :lol:
