Thanks George. Yes, you’ve hit the nail on the head about those 6 cell modules. Each module is one big parallel ‘slab’ as you put it. You just line them up, each one alternatively facing up or down so that they will be in series when you connect them, then solder between the modules. Here are the instructions for that type of pack: http://www.diybatteries.com/2016/10/23/how-to-build-a-diy-powerwall-with-maker-batteries/

They’re easier to assemble than the triangular modules, especially for someone that has never built a battery before, because they’re just more straightforward. The triangular modules allow some interesting shapes to be made, but the straight modules keep everything nice and simple in terms of the soldering layout.
