Our dire hopes is that it will fit in about above NiCads and just under NiMH is, and at a cost of not much more than advanced Lead Acid. This will be a poor Man's NiMh, with support from the grase roots (Us Evers). Give the efforts that we can bring to bear, this could out range and out perform the $30K battery that's keeping us in the dark. It should compete rather well with just about all the chemistries out there. And be controlled by us and the market. The Big dogs have totally ignored the NiZn, and I hope this is to our best interest. A lot of us are going to find out, When we actually get the batteries in hand, and have some support. We have great support right now, but not much battery Stock in country.
