New 2 stage PD lithium Converter charger yet?
When I installed lithium batteries 18 months ago I also changed out my converter charger. I didn't want it constantly charging 14.4 volts. so I returned it and have been using my original PD convert...

Battle Born (among other LFP makers) has also influenced PowerMax in their design of a charger. See BB's comments here (scroll down)
The PowerMax has a big advantage over the PD in that you can also choose to manually adjust the charging voltages to your own idea of what your LFP needs, to do what you want. (Some like to use lower charging voltages than the fixed 2-stage ones) Price is probably better too.

BTW I really hate the way BB uses "Absorption" for the 13.6 stage and "Floating" for 13.2v. In real life, the Absorption Stage is when amps are tapering following the Bulk Stage, but the charger's voltage remains at its Vabs setting of 14.x.
It seems to be a losing battle with these companies to get them to use proper language for charging profiles. :(
On voltage choice, we know that with FLA./AGM the standard 13.6v works when on shore power and you are using 12v things while camping. 13.2v is only for "storage" when not camping.
I am unclear what goes on with LFPs for that, where many say 13.6 is too high with LFP for "Float", but is it too high for while camping using 12v things? Perhaps there should be a new set of voltages for LFP for what to use while actively camping and what to use when the rig is not being used? The PowerMax can deal with whatever is chosen of course, having the adjustable voltage option to it.
