They are GREAT cells, I can't believe I never heard of them before. Each cell is 400 g, 48Wh , that makes them 120Wh/kg, decent.
Their new 10Ah cell that will be coming out this year they say will be ~140-150Wh/kg, apparently.
I will not be running a BMS for it, it will be balance charged and it will be in a hermetically sealed battery enclosure (at least that is the plan) made fom machined black poly block, with handle formed into one end for easy carry. I am not running BMS because I really don't think it's necessary, for these reasons:
-They are A123 cells..... come on
-Will be balance charged, so you will see any cell that would be out of wack
-Discharged typically 60% DOD
The guy I am buying from says they are rated 15 year life, and 7000+ cycles @ 80% DOD. Cheapest battery over it's life compared to any other battery by far, by far.
