How to Construct an A123 20Ah Pack

I've been thinking of how I'm going to series the 13 or 14 cells that I'm buying from Oatnet in order to make a 45V pack and I think I've settled on a simple method. It's best outlined by poster named Electrodacus.

He simply folds the tabs over each other and drills holes through the tabs and uses 3 screws with washers to connect them. Since I plan on putting them in series, I simply need to alternate the packs so that the positive and negative terminals connect so that I make a 13 or 14 pack. I hope to get the packs by this weekend so building the packs will be my latest project!

I don't have any unused printed circuit boards sitting around but I do have some bits of formica which I think would do the job well.

More later,
