So I had a scare with my battery and decided to order a new Limefuel. I was happy to see the 6000Mah is available on Amazon! The Limefuel web site still lists the 6000's as on pre-order so not sure what's up with that. Anyway I trust Amazon (even if I'm not 100% sold on Limefuel). Amazon will take 'em back if I don't like them. They should be here on Feb 11 and I'll report back then. But has anyone tried them? The 6000's not the 5400's that is. Thanks!
