Turnigy 4000mAh 2S 30C hardcase pack

Well I picked up a pair of these out of the USA warehouse . All I an say is wow the value of these packs are great they have nice thick wires and can definitely dump the amps with very little voltage sag . Probably the most notable thing is that these packs live up to there rated capacity  But I don't plan to buy anymore of these after trying the Zippy 4000mah because the case an finish is much better in my opinion .

This pack has a Relative Amp 30C x 4A = 120rA 

$19.99 / 120rA = 0.166cE the lower the number the more Cost Effective
