MetalMan, I think that configuration would actually fit! I hadn't thought of that setup, so thanks for the drawing. I've been thinking about it though, and it looks like it's gonna be pretty expensive after all to do a 6S2P setup with A123 cells after all. Obviously the DeWalt packs only come with 10 cells, so buying another complete pack (or even just two separate cells) would begin to work out to be kinda expensive. Also, wouldn't the spot-welded tabs strangle current output? I've not used A123 before, so I really don't know. If I went with 5S2P then I'd obviously lose quite a bit of top end, and a box-stock nitro Havoc is capable of 55mph...so I'm aiming for that kind of speed.

You're right, 2 Dewalt packs are pretty expensive. But 6s2p A123 would have no difficulty pushing that truck to high speeds. As for the spot welded tabs, I've not noticed any issues with them being able to supply enough current.
