Looking for "safe", long-running Lipos for my set-up

Hello,

Well, sure the 3000mAh are cheaper, but you have to buy 2!

Current prices:

Two 5S 3000mAh 30C Zippy = 100$
One 5S 5000mAh 30C Zippy = 80$

Sure you gain 1000mAh, but it's also 20$ more expensive. I don't think you save money by buying 2 smaller packs.

On the other hand, is it easier on the batteries if I use 2 packs instead of a big one?
