I was wondering: How might charging work when you hook up the radio battery (deep cycle marine 720 aH) in parallel with a truck's battery, hooked up so that the radio's battery can be easily connected and disconnected at 10' away from the truck's engine.
If the truck is not running, what sort of "leveling" between the two batteries might be expected? Would the truck battery try to feed the other battery?
The radio and its battery would be.. real... auxiliary in this mode, and would be looking for a place, absent solar, to get an easy charge in a slow way from a parked truck. Would sooner not run the truck too much just in order to charge a large radio battery.
A solar panel is probably the best answer, no? Could anybody discuss and justify their solar wattage preferences for running an HF radio in the usual monitor/transmit ratio that's been posted here? I've seen some links to vendors on another thread on this forum. Due to this forum being not like another one, I hope I can ask this question and not get hammered for my lack of situational awareness... which, I confess, is lacking. I did not utilize the search function prior to posting.
