Wayne et al : The closet thing I have seen battery-wise is a brand of LiFePo4 batteries called Anti-Gravity designed as replacements for conventional wet-cell motorcycle batteries. This one is 4.25 X 1.25 X 3.75 inches @ 6Ah and weighs in at 1 pound.

These should be available at a local motorsport shop. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
