Amazing what a couple of years can do... when I got into the lipo game with 18650 cells for my flashlights the Trustfire (don't laugh) flame 2400 were the best bang (hope not) for the buck cell out there. The Tesla Roadster was being built with 2200mah Panasonics. The Tesla S is being built with Panasonic 18650A cells at 3100mah. From what I've read the 300mile range pack is going to be built with the now available Panasonic 18650B 3400mah cells. Elon gave a speech recently about capacity gaining about 10% a year (real world, not press releases for lab potential gains). On a Tesla forum, some of the Roadster owners are almost begging to get their packs rebuilt with the new 3400mah cells. For me this new cell means about a 1/3rd jump in real world useful time over my present cells, for the Tesla guys it would mean a jump to over 300 miles range in a Roadster.
Now to just find the best place to actually get the real cell without paying some premium because the supplier sells to police and survivalists. I see some selling them from about 8-9 a cell but the players are selling for 2-3x that amount per cell... plus shipping/handling fees. Are the counterfitters already faking these? Anyone have a good cheap source for real cells? Might buy 8-10 of them if the price makes it worth it.
