12 v to 12 v trickle charger
Any suggestions? Looking to keep a 10 amp-hour AGM charged while running the Pinella Remote. I think a trik-l-start is on the large side.

I have a 18Ah AGM battery I use as a portable 12vDC source, or as a jumpstarter for other's vehicles or an emergency additional capacity to parallel to my regular battery
Obviously, I like to keep it topped off and not worry about doing it regularly when not in use.
I make extensive use of anderson powerpoles and put one of these Ideal Diodes inside an old smoked wattmeter casing with powerpoles on eachend. I hook up the Diode in series to my 18Ah AGm and anytime my charging system's have system voltage up above that of the 18AH AGM, the latter gets fed voltage just 0.04v less than than upside the diode, and when system voltage falls below that of the 18AH agm it cannot backfeed.

So anytime your regular charging system has voltage up above the voltage of the generator battery, it will charge the generator battery.
The 'Ideal Diode' only drops 0.04v across it, but I am sure some are frothingly ready to tell me/you/ the world, that they drop 0.7v or 0.4v.
These are newish products. I have passed 40+ amps through mine and actually put one permanently on the output of my Meanwell rsp-500-15 40 amp charger/power supply so that I can unplug from the grid and not have the additional fans and powermeter be powered up by the battery, without having to disconnect the anderson powerpoles. I've a third one awaiting a duty.
I also make extensive use of voltage buckers and boosters, and sometimes combo buck/boosters, but I would not use them for your intended application, if I were trying to accomplish what you are.
The 0.04v loss across the Ideal diode, makes achieving proper charging voltages a non issue. Your wiring to the diode from your regular 12v system is not even all that important, if all you want is a 'trickle'.
But your solar, holding system voltage up above 14v for hours could overcharge the generator's battery with the Ideal Diode.
The Ideal Diode goes on the positive line but needs a negative wire soldered to it as well, to function properly, otherwise it drops 0.7v and does not act like a check valve. Follow the directions.
Has anyone actually fed a 3 stage solar charge controller with an ~ 20v DC power supply instead of a solar panel? I know its been discussed often, but I've never read of anybody doing it and posting back how great it works.
