What I learned about maintaining batteries while boondocking
To charge with the onboard or use an external stand alone charger. Here's what I concluded during my week of boondocking. https://youtu.be/IgQTtnEXlU4

Oh woe
Vf is not static
It may be 1.3 volts at 20 amperes
And .8 volt at 5 amperes.
Because of dropout (?) Specs
Impressively rated buckers are scarce as hen's teeth. I used to use the old TRACE C30 C40 C60 solar controllers but they dried up.
But but but but but....
There IS a way to tame the beast and no one remembered it from this forum...
Shame shame shame...
A
VARIAC
Pluggem in twist that dual. A slowpoke could set this up in 10 seconds.
TWIST THAT DIAL!
Throttle that amperage!
Want more than rated output?
TWIST BABY TWIST! Make sure the load isn't bigger than the VARIAC
And don't go insane overamping the charger.
Variable transformers are useful. Manual chargers are priceless. Reminds me. I have to go to the dump today with nine Phsmart Chargers. From control circuitry to rectification those puppies are doggie doo. A Good smart charger would use a massive capacitor, a 100-amp full wave bridge rectifier plus a comprehensive menu plus override PWM control and suitably heat-sinked MOSFETS and that my friends Ain't Gonna Happen.
