On a mission to find the batteries i want... if they exist.

well have made the foray into a pair of 5s1p 30c 5000 mah zippys. now to wait for the shipping which is always the hard part. so can you guys tell me what power i can expect compared to my humble 5s2p 4600 mah a123 cells? would it be murder on the truck running them in parrallel or pure idiocy? i got some more parallel cables in case.

this will be the litmus test to decide if i kep the li-po or the a123s.

thanks chaps.
