Solar Battery Charger and charging a spare car battery?
Comments

Cheap inverters are about 30% efficient. Charging through inverters is not recommended.
I agree on the above the only method is a split charge relay, But if your not allowed to modify the vehicle your a bit stuck.
How will you clamp the spare battery down? Also mentioned above batteries give off explosive gas when charging how will you vent it?
Then you need to run wiring to and from the batteries.
