ok, lots of good info here. I'm especially interested in the 13.6v float (3.4vpc) since that's what my PD9130 that's in there already puts out constantly if I remove the charge wizard pendant.
I'm thinking now maybe I keep the PD9130 (without the charge wizard attached), and add a separate charger in parallel for charging the lithiums. Could it be that simple?
Full disclosure, I already have the 130ah cells, they were pulled out of my old electric car before it got towed to the junkyard. I will be using these batteries (they are a bit hammered after 20k miles of 500+amp hits, but still show decent capacity). I also have a Manzanita Micro PFC30 charger that I'm thinking I may be able to use as well, just in parallel with my existing PD9130 converter. I previously didn't think there would be a way to use the MM charger since it simply shuts off when charged (no ability to use as a converter for house loads when plugged in, and no ability to auto-restart).
