Lithium requirements

[JCR]

I read that lithium has to have special chargers to charge them up. Would a trucks alternator during travel charge this type of battery or will it harm it. What about the trailer's conventional converter? Will you need to change the converter to a lithium capable charger (converter). ?

The truck's alternator will not deliver a perfect charge, but there are ways you could solve that if you wanted. You could run a dedicated power feed of appropriate size from the truck battery to the rear of the truck and give it a separate connector, then feed this to the trailer where you install a dc to dc charger that supports lithium.

Some trailers have converters that are already lithium capable.

Appreciate the comments.. I also could probably use my 120 ac v onboard truck power inverter and use a standard lithium ion battery charger and run a line back to the terminals ..

I just got a new truck with 120v in the bed. I will be running an extension cord to my charger at the TT battery. Also, if needed, I will simply bring the battery in the back to the pickup and charge it as I do my day to day travels without the trailer.

There is really no issue with going lithium except you should pay attention to the battery and its BMS settings. IMO, some sort of battery monitor is necessary.

Most Lithium batteries come with a bluetooth app that can be monitored and in some cases programed.
