I agree. I would either use those panny's. I am personally going to use the vtc5's or the purple 35 amp efests I have till I get the money to order a couple of the new 20 amp 3100 mah purple efests. I think those will be winner's. But ya, you really don't need anything much over 10 amps. Although I always like to be a little higher to play it say, which is why I want the extra mah but still feel safe with the 20amp.
Cactusesmokes.com Has them for 10.99 a pop free shipping for the weekend. I think these efests will be a great battery for these clones
