         These batteries are not as heat sensitive as lead acid or 
other battery technologies. If they don't work for ten years, you get 
that fraction of your money back.

         These are really high quality state-of-the-art batteries.

         I came out with LED position lights before anyone else did. 
They work great, pass FAA specs, and are less expensive, (still,) 
than anyone else's. I plan to the same sort of thing with batteries. 
Other folks will be selling batteries like these later, but, if 
enough folks are interested, you will be able to get them from me 
first, for less than others will charge later.

         In about a month or so I'll "let the cat out of the bag" and 
reveal the manufacturer and the details. For now, I'm just trying to 
figure out if it is worth my time to develop a product.
