Default Buying Batteries

Hi all,

After a crash, I replaced a boom, grips, blades, and tail case. I went to spin her up last night, and she wouldn't turn over.

I probed the Lipo's balance connector and found that the first cell is dead. There is connection between the balance wire and the metal tab coming out of the LiPo, but the cell produces no voltage.

In any event, I'm looking for some batteries. HD has some "Mega Power" batteries for about $47 each. They are 20C 2100mah.

Some people suggested Common Sense RC for cheap LiPos, but I didn't see any cheaper ones there.

Anyway, are the Mega Power batteries okay?

Is there a better place to buy?

I have one of the batteries you are talking about and it seems fine to me, I have quite a few cycles on it and it has some kick when pitch pumping but I am not a great pilot so take what I have to say with a grain of salt, I will most likely pick up another on soon.
