That's cool. How much are the Astro motors? What controller would he have used? .......NVM, I searched and found it: $400 not bad!

I am wondering if these are a good buy? They are obviously genuine A123's, and they are a decent(ish) $8/cell, which I wouldn't mind paying the extra bit if I know what I am getting. I keep thinking $400 is alot for a battery for it, but then I remember that if you would buy a purpose built ebike battery, you are looking to pay $500-$600 for the same range, and then the cells they are no match for an A123 based pack... very inexpensive in the long run.

At least 2000 cycles @100% DOD x 20 miles range = 40,000miles/65,000km Then even after this point, the pack would most likely still be around 80% capacity, still perfectly usable IMO. $400/40,000miles = 1 cent per mile of battery cost over the life time.
