I just purchased a rimfire 60 and a 60 amp ESC for my 60 size christen husky. I was wondering if I used 2 each 2200mah 3S lipos in parallel if that would give me the equiv of a 3S 4400mah batt? Or maybe that is too small?

Well, you're correct in your math - the result will be 3S 4400mAh pack equivalent. Unfortunately, that Rimfire 60 motor is rated for 5 to 6 cells, so it's not going to give you much power on 3S. You're gonna need some bigger batteries!
