All you have to do is charge them fully to their higher required voltage periodically, not constantly. And except for most of us older farts with older vehicles, I would expect most of the newer / newest vehicles will do so sufficiently. Charging at 14.6-7 rather than 14.2-3. Too, having solar...
lol. I'm starting to think it is just some clumsy surreptitious marketing campaign by Redarc, given the profligacy of DC-DC / Redarc threads in recent weeks. Or some fount of 'Youtube influencer' is producing all this muddled nonsense. ~$500 'solutions' to $50 problems.
$30 solenoid, keyed-power triggered, tied to your factory alternator / starter batter charging circuit, and sufficiently thick wiring to pass the full output of your vehicle alternator to your aux. It's brute simple and reliable and inexpensive. And utterly bereft of 'smart' points of failure...
You should all look @pappawheely 's build topic. He's built a very interesting battery tray design that hinges down from between the frame rails of his intended moving van body / camper / mobile freelancing photo work studio which he'll take throughout the southwest for covering off-road races...
@pappawheely If it's for your mobile studio, take a look here

Lots of interesting home-brew systems being set up, using various lithium tech and the 'energy density' is a lot better than...
"My vehicle isn't a daily driver"
If the use is infrequent and irregular, I'd suggest building a battery tending station in your garage and simply dismount those batteries and leave them racked until you plan to use the vehicle. As some car collectors do.
Or conversely, put the charger in the...
A fixed tank or a storage space for a bladder is a lot of dedicated volume. And a lot of shifting weight, baffles or no. And with a powered pump / pressure system it would be easy to use something like 20L jugs and carry more or less of them as needed, distributed, switching them as needed...
Serrated carving knife, longer the better. Shallow cutting angle, long draw, light pressure. If you just hack and saw you'll get a terrible ragged cut.
Different meters, different readings. Take the measurements at all those points with the same meter, if you think you've got something odd going on. Consider the reports of several different devices nothing more than a rough guideline.
Looking good. How are your holding the outer box in, are you tying to the 3rd row seat brackets?
And your pics remind me of something else I need to take care of - that damned loop handle on the Liftgate. I've banged my head on it laterally more times than I can count. Need to replace it with...
Rear brakes are in and basic break-in done. Definitely need new rear seals (and bearings), with the rear disk/drum rotor off, lot of fuzzy grease built up around the axle shaft
Next up is UV light test on the back side of the AC Condenser tomorrow evening.
I measured about a 5/8" shift of the rear axle towards the passenger side, between at rest wheels on the ground and jacked up / wheels off / axle lowered close to max extension. I used a plumb bob off the outer face of the frame rail directly above the top of the axle tube.
I'm thinking...
Nice work on the pullout. How sturdy is it all when it and drawer are fully extended?
I haven't used my propane two-burner in so long I never even mocked it up with my setup.
Crew Dragon astronauts are knocking off for a sleep period and the weather here is cooperating, so I'm about to head...
10L nato metal and no venting / liability BS. No real issues about storing. And it's easy to add a lower vent if you want those imaginary propane vapors to fall out.
