I want these.

NMC..Nice but,.. I hope you have a strong Ebike to carry the 65kg they weigh !

These would be more small car territory. No reason they could not be sized smaller for a bike, though. These allegedly have mucho charge cycles compared to lipo or lithium iron.

Yup, it's NMC, Lithium Nickle Manganese Cobalt Oxide. Its about a million times better than lithium Iron in safety and life cycles and energy density. It's what all modern EV's designed by non-retards use for batteries these days.

Price?

For us morons, Is this the same chemistry as the Ebikekit was using? Same as the bottle batteries? Same as Allcell?

Part of my problem is some chemistries seem to have multiple abbreviatons.

Price?

$9,300 according to an article in the Economist http://www.economist.com/node/17352944
To put this in perspective, it would take 4 of them to power a Nissan LEAF. This size module isn't appropriate for a bike, but the Li(NMC)O2 - Lithium Nickel Manganese Cobalt Dioxide - battery chemistry is promising.
The cells for these modules are made by Dow KoKam http://www.dowkokam.com/tech-cells.htm , and they make smaller modules http://www.dowkokam.com/resources/Dow_Kokam-BB-3590.pdf

Lets do a group buy and split them up!

6.5kwh / 4 = 1.65kwh per person
$9k / 4 = $2.2k per person - totally worth it

I wonder if we can get them to sell the naked cells? Ha, yeah right. I bet they make all their money off the BMS and packaging. Any idea of what DOW NMC costs OEM per Kwh?
