Battery 2 Battery charger.
Lithium batteries operate with higher voltage than truck alternator provides, so you need B2B charger and also solar charger + converter who can adjust the voltage.
Some RV owners have power obsession and Sprinters owner are generally willing to spend more money on gadgets, than TC owners.
Cover your roof with solar panels, add lithium battery bank, replace chargers with computerized system and you can easy spend 5 grands on the project.
Some owners make 2nd alternator just for lithium charging.
