Parallel battery charging will never be ideal but with larger wires it can be more than adequate.
In the "old days" this was true. "Smart charging systems" are not smart enough to accommodate 2 batteries in parallel that have greatly differing states-of-charge !

DC to DC chargers like the CTEK are ideal for charging the remote battery but even a 20A unit is pricey.
I agree 100% with you there !

The ideal battery wiring for parallel batteries is balanced wiring and used for adjacent batteries. But it's impractical for isolated batteries.
It is not just the wiring ! It is more the state-of-charge of the batteries and what The "smart" charging system
thinks it knows about charging them.
