Yes, that's right. It didn't even occur to me consider the different temps.
Thanks for all your help Salvo. I am going to consider all you've shown me.
In the meantime, I am going to mess around with my little gophert 1620, and see how fast it raises the voltage to about 13.8 volts, at various soc's. It can be easily hooked up to the bank via a pair of clamps onto a pair of studs inside my inverter cabinet. Not ideal, but it would only take another couple minutes of my time to hook it up and then pack it back away.
I'm also going to see if I can find a reasonably priced electronics guy to look at both the Turnigy and my Peak 40 amper. I'd like to modify the voltage output of both, in a manner like smk suggested. And Landyacht did some similar mods on his Mean Well.
