Normally those 2200mAh packs are designed for 1/18 cars, I have actually tested them in a 1/10 car hooked up in series to act as 4S for grins so it's possible to run them in 1/10 but don't expect very long run times:


the 7600mAh pack is definitely more suitable for 1/10 cars and what I would prefer, some of my very first LiPo packs were 20C and they performed perfectly fine for brushed and brushless applications for 1/10 cars back in the day:
