You can look up the specs and manuals for your model on PD website.

It is not lithium ready but there is a charge wizzard mode select button (next to the green flashing light). I can set it to boost mode and it puts out 24.6vdc for 4 hours then it reverts back to normal mode automatically.
I put in 4 lithium batteries and I kept the original (new) FLA battery as a back up. I installed a battery select switch so I can control which battery group is selected.
As said above, lithium batteries charge fast.
Just don't charge them at below freezing temperatures.
Here is an excellent article about it.

I dont think the output voltage in boost mode is actually as high as you are stating.... I think it is more like 14.4
