Those A123 cells in dewalt config do fit perfectly in your savage (i'm not as lucky as you could be. I do have to brake them apart in 2 5s1p packs). At your place i would solder some cables+connectors and shrink wrap them without braking them apart. And then aim for a 10s1p A123 setup -> MGM 9032 and Neu 1515/1Y (1100kv). Crazy power (up to 2.5KW) and cool running components. Running time and weight could be optimised with 8s lipo in the future. That's what instantly popped up my mind when i saw your dewalt style pack config fitting so nicely inside your savage.

Sorry can not help you with your balancing questions as i do not balance my A123 cells at all. I connect 2 packs in series and charge them with a hyperion 1210i as 10s1p with 5A (35min charging time). My oldest pack is at 70 cycles and still takes 2250mah after a run.
