battery question

[ls1fst98]

I am looking at buying new batteries. i have 2 turnigy 2s 5000mah 20-30c batteries now. i have multiple cars, boats, and converted revo. what i have now uses either 2s or 4s batteries and im building a 6s twin genesis. can i be safe in ordering 6 2s 5000mah 20-30c turnigys like i have now so i can use them in everything or do i need to go with a higher c rating? my mean machine is a turnig t600 1400kv with a 200amp suppo esc to be run on 6s, the twin cat is a daytona with twin t500 1300kv with turnigy 180a esc's wantiing to run 6s per side.

You want at least 40c in boats.

Yes with those setups it is time to up grade the C rate,
To keep the setups happy and they will run a lot better to.

thanks guys, can i run 3 2s in series to get 6s per side, this would make it easier to run 4s in my revo and sv27 still so i dont need a bunch of different types of batteries. my other thinking is it would allow me to move batts to change cg for water conditions.
