Yes, me too. Would like to build a 52V, 14PS6 battery. My frame triangle will not accept currently available packs, but does have enough room for the right dimensioned pack…
Would also like to have more information on the cells used in the triagular or linear-3 pre spot-welded packs. Is it possible to get them with various cells (ie, 20R, 30Q)?
Finally, I watched the video of Micah assembling a battery pack out of the triangular 3-cell packs. Since we are soldering the connections between packs, is it still necessary to use nickel strips? Would a single copper wire of appropriate ampacity also suffice? Seems that would be easier than soldering multiple nickel strips…just asking.
