BMSBattery offers some NMC battery packs, weak stuff though, 1C, prolly less in reality.
Batteryspace has some LiMnNi and NMC stuff for sale.
All-battery sells the tenergy v2 cells, but i am not 100% sure these are NMC.
Allcell is claimed to be li-mn, but i think it's NMC? Higher density than RC Lipo by a long shot, but only 2C max.
All close to, or exceeding the density of RC Lipo.
Most have low discharge ratings, however.
What we really need is something like the Dow Kokams, but cheaper.
Yeah the bmsbattery nmc seems to be a good choice for long cruises where you would set your current to 1-1.5 c max. But bmsbattery seem to lie about their size and weight ?
I must admit I've not heard of the allcell linm ?
I was partly following the dow kokam thread, but from what I gather they are not much more energy dense than lipo ? + they are harder to assemble for the average diy man, but they come in 16 or 20 ah cells greatly reducing wiring.
Anyone know the life cycle of nmc ? I would be interested because of the leaf when one becomes available at a decent 2nd hand price!
