Just purchased a new 2024 Jayco Eagle 25RUC with lead acid batteries installed. Does anyone know if I install lithium batteries whether they will charge from my truck on the road without any modifications? The coach does have the switch for lead to lithium.
Thanks in advance

From most of the many threads I've read the past few months the truck will not generate high enough voltage to fully charge. But fully charging lead acid wasn't reasonable either.

I agree. The tow vehicle is not designed to charge lithium batteries however there are modifications to the tow vehicle that will.


OP



Do you have solar? Solar could be your answer for charging the lithium batteries when not connected to a landline
 
There are chargers designed to work on the voltage your truck puts out and then boosting it safely to charge a lithium batteries. Many posts here, try DC to DC charger for lithium battery here and on google or Amazon.



Your built in charger will bring your lithium up to 80% and may get it higher over time. I have 200 watts of solar and a Renogy MPPT that keeps my battery filled up even off grid. Went to Great Sand Dunes NP last year and it snowed nightly with the LP furnace running and back to 100% every day!
