This has been a frustration for many of us in the DIY EV community. A123 cells are outstanding, technically speaking, but the company refuses to deal with individuals.
There are two places where A123 AMP20 cells can be purchased, Maziven in the UK, and High Tech Systems in the US. Both offer cells in the $60-70 range. The gray market cells are far less expensive, I purchased them for around $25 each (including shipping). Yes, these are probably rejects, as they test below the rated Ah capacity of 19.6, but my average is just below that rating, at around 19.3-19.4 Ah.
Other than slightly lower capacity, the cells I have appear new and have also tested well at high current, sagging about 23% at 372 amps with a resistive load. I have seen no failures yet after testing more than 300 cells.

Over the last week and a half I have been emailing a123 and a123 "authorized dealers" and have not gotten any replys.
I at least wanted to price authentic a123 AMP20 cells and see how much they cost before going straight for the a123 rejects.
Maybe I should try emailing johnson controls.
