Methods has also bought cells from Victpower, all his findings are in his thread. This are bigger and heavier than hobby city type packs, but there are less connections and they are CHEAP! I have never used the cells, but I fully intend to! There are some people working on building solutions for the cells on ES, search the forums and see who is doing what. I'm half tempted to make some crude bar clamps and be done with it, I won't pull more than 80a from the pack.
I bet what happened (me just guessing) was that the cells were destined for pack building, then the whole GM bailout happened. a123 probably got a cut of the bailout for the product that was already made, and the homeless cells got sold through factory contacts back into china. Now they are absorbing the cells into their own supply chain and there are cottage industry businesses picking up on the grey market need for cells elsewhere in the world. A grade? B grade? How will we know until years down the road? Doesn't matter and i don't care, I'm willing to take a gamble that I can get a year of use at 4c bursts and 1c average rate.
