After reading the Zippy thread, I'm returning an order of four Zippy-H 3S batts to Hobbycity in favor of something better. Unfortunately, they'll only give me store credit(won't be ordering there again...) so I have two choices for good batteries:

Do I go for the higher C rating, or the higher Mah? If I have my math right, they're both good for 150A...
