Is it possible to run a jb3 off of a 9.6 v rc battery pack similar to what the ua-5 can use?
That is what I'm doing. I'm not sure whey everyone else is using 12v... I may be missing something, but I think your batteries are most efficient the closer they are to the voltage after the converter. I think the more voltage that the converter blocks, the more amprage is lost in the conversion. Also the rc's are much lighter, and charge much faster. I originally thought I was going to go 12v, but the guy at my local "battery-plus" store told me that if you charged your sla on anything other than a trickle, it would reduce the life of the battery. Maybe there is an advantage to the 12v and one of the "car convertor hack" pioneers can answer that for us. (Thanks again guys for all your research and tests on this thing!!!)
