Hi all; Just wondering if anyone has tried the new A123 batteries for ign. yet. They just could be the ideal battery for our needs as they are 3.3 volts with a very flat discharge curve. You would only need one cell which would cut down on space, and only one connection. The only thing I have not been able to nail down is how to charge them. I have been using 3 NIMH batteries, and these seem to work fine, but it would be nice to only use one cell. The A123 batteries from all I have read so far are much tougher and don't have the problems that the Li-Poly's do. For the HIMH batteries, I use a 15 minute charger that charges indivdual cells, so have to remove them from the plane to charge them. I know I could get a special charger that would charge them in series, but have just been using what I have. I use a 4 AA battery box from Radio Shack, and cut one cell holder off to make it a 3 battery holder. The A123 batteries are really new tech., and that is why I am asking here for info. Thanks
