So right now I have 2x ZIPPY Flightmax 4000mAh 4S1P 45C for 8S total.

I think I want to increase the Amp hours for a little more ride time with 2 more 4S packs in parallel. My first instinct is to just get 2 more of the same because everything works well as is and that seems to be the smartest way to add on.
But I'm also looking at the Turnigy nano-tech 2650mah 4S 25~50C because of the price, or maybe just shop for high Ah to just get more storage, lower C.

Is there anything I need to know when mixing and matching these LiPo packs? Does the "C" need to match? Thanks
