Yep, those are the packs... They should be in this week - placing the order tonight - looks like I'm going with the LVD that Coolhand showed me or the HRPOLY-X - I'm going to run tests and decide which I like... I'm going to be selling them in a few different kits etc (with charger, with LVD, Seperate, etc. - now that I think about it, an E-maxx pack would be a good idea!). As for 3s, I believe they are on the way, but not in yet... Seems to me that with the weight you lose, these packs are going to increase speed by a good amount.
