Quark durability test

[BrianG]

I've been really watching those A123Systems batteries at various places and they seem to be really nice with their high discharge and charge C rating, and safe! I just wish they had single ~4Ah cells. And then you need a charger/balancer that is specifically designed for a 3.3v nominal cell, which requires you to get their specific charger.

By the way: what is a "slipperential"? Is it a center diff with a slipper directly on it?

Will those Neu motors be available in different (smaller) sizes - like the equivalent of LMT 1940/1930,1920?
