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

[magman]

mah. affects run time, the higher the mah, the longer the runtimes. However, the higher you go, the more they weigh. ... the higher the C rating, the better the batts. hold their load under stress and better they are put together

If it was me...I would opt for the 2 batts and the ccneu motor. The turnigy;s have been doing well as far as people not complaining about them.

And you can get a Tekin motor or a ccneu for under 175-
