The Shelf life in the spec. sheet means that the charge of the battery (usually 40% of the battery capacity) from the manufacturer will self discharge after 6 months.

Lots of places cell limn.... Check on aliababa.... for right now I'd say DOC will have the best deal since he uses quality cells to start with and does his own QC.

Have hit up the googler with limited success. Wikipedia says that NMC batteries are the most energy dense. BUT.... what downfalls, if any, come with that density..
Apparently the Nissan Leaf is using these according to wikipedia... but who else?

I know you are probably under some NDAs because of your job, but can you tell me this; are those cells the best of all worlds, IE 3-5C+ nominal rate, good cycle life, good safety, *and* improved density over these LiMnNi ?
IE much like these cells we're talking about, but better whr/kg & output?
http://ebike.ca/store/store_ezee.phpFor those who require greater range, there is an upgrade to a 37V 14Ah option made from Samsung LiMn cells, with the same dimensions and weight but 50% more capacity.
