I have two 100 ah lithium batteries in our travel trailer. I'm still using the original converter that came with our 2012 trailer. However, I have 700 watts of solar on the roof and it feeds an MPPT Morningstar controller. The folks at Morningstar helped me write a special program to charge my lithium batteries at 14.4 volts for a specific amount of time. I also spoke to the folks at Progressive Dynamics (makers of my converter) about whether I should 'upgrade' to a specific lithium converter, and the tech I was speaking with said as long as I had the solar system up and running at the same time i should be fine. So, remembering what a PITA swapping out the original converter was when it died, I'm going with the advice from them.
Yes, that should work. The original PD converter will only be able to charge your Lithium batteries to around 85% State of Charge due its lower voltage, but the MPPT solar controller should be able to top off the batteries to 100% charge.

What do you think, Mike?
