[QUOTE="condor22, post: 134688, member: 1932"] I'll add a little to the above, When I'm driving, I am charging my Aux battery with the BCDC1220 20A smart charger, my Engel is on and drawing up to 3.0A (@ 30% on/off). So I'm putting more in than I'm taking out and therefore NOT cycling the battery. I stop for a days prospecting, say 6 hrs. My Engel thermostat is cutting in to average about 1/3 on @ 25 C, so I have used 6AH approx. I drive back to camp it charges some of that use. Camp up overnight, (15 hrs) no driving and the Engel uses another 5AH. If I only drive for say 1 hour, I'm not going to put all of the usage back in, because smart chargers in Absorption mode, have a reducing current (amps). To overcome this, when I park up to detect, I open a 110W concertina solar panel on the roof, or windscreen, or ground. It not only charges what I am using, but also the previous overnight use. I also carry an 8AH 240VAC to 12VDC charger that I can hook up to my generator and the aux battery, back at camp. This also allows me to charge my caravan battery from the other genny outlet.
