I bought several SMC packs about a year ago. All I can say is; they are the best batteries even if they were twice their price!

They continue to have low IR and maintain high mah for any given pack.

I'll not be buying any more batteries for a while as I don't get to race as much as I wanted, so my packs continue to perform as they did when brand new. My packs have ~20-30 cycles, if that helps anyone determine what a great battery SMC sells.

BTW, they totally out perform my Gens Ace batteries under the same conditions. Not such much as when both were new, but, after ~10-15 cycles, my Gens Ace started dropping in mah they held, and the IR rose quite a bit.
