Are lithium batteries worth the cost?

I installed a 100AH Battle Born battery and Progressive Dynamics Lithium Convertor in my trailer. No maintenance, no removing the battery during the winter, no battery tender during the off season. I don't obsess about SOC and all the other stuff in this thread. I just ignore the battery and expect to do so for the next ten years. So far, the battery meets all my needs. So, for me, the lithium conversion was worth it.

If that means you are leaving it plugged in for long periods of time doing 14.4-14.6 after it has been fully charged, AFAIK, that would be against Battle Born's guidelines.

Some say to isolate that PD Li converter from the LFPs soon after the batts are fully charged. You still want the converter on in the RV.

That PD Li converter might have been a big mistake in their rush to have something to sell with "Li" written on it.

Agreed, I have no idea why progressive dynamics thought a constant 14.6V output would be a good fit for a lithium battery. You want to shut this off after the battery is charged, or better yet just use their regular converter, which is better suited to lithium.

Let me get this straight. Progressive Dynamics, a leader, designed a convertor for lithium batteries that isn't as good for lithium batteries as their non lithium convertor? What if I just unplug the convertor between trips, say three weeks? I do disconnect the battery during the off season. I wonder why Battle Born sells my exact charger for use with their batteries.

Yes, Battleborn may "recommend" the Progressive Dynamic single-stage 14.6v Lithium charger, but they qualified that recommendation when I called them a year ago. They "suggested" the PD Lithium single-stage 14.6v converter/charger not be connected to their battery for more than 2 weeks *if* it wasn't being used/discharged during that time. In other words, don't float the BB with this particular converter/charger for more than 2 weeks.

BTW, PD is fully aware of BB's position on this. They told me a year ago they were working on releasing a 2 stage lithium converter/charger line that would float at 13.6-13.8v.
