The buzz from Davenport is the Shorai lithium battery:
they make one 6V unit and it's 18amps in a very small size. Designed for motorcycle use so vibration shouldn't be a problem ... Perry


I was out looking at batteries for some work stuff and saw this one -

6 volt.
13 amp.
5.4"H x 2.8"W x 4.2"D

It looks very close to the dimensions of the H-3 to me and iis has13 Ah. Not a battery for judging, but maybe another alternative?

Since I have not used one of these and obviously all of you know much more than I do I'll leave it to you if this might work...
