Ok, I picked this up from the local guy converting there. Its pretty nice. He puts rubber feet on them and red lights to show its powers on. I tried to hit it "hard" but all I could do was 2s @ 30 amps. The fans didnt even lick in hard lol. This thing is SOOOO quiet. He had like 6 different ones in his shop. He let me pick what style i wanted. This one was quiet, small and powerful. I need to find someone with a 4010 to hook up to it and try to charge 2 packs at 40amps. Just to see if I can get the fans to kick in hard lol.
