We're running a Monoco 1995 40' XL and it's time for new house batteries. We have two Zantrex Freedom 458 inverters and 6 lifeline GPL 8DL Batteries. I checked with Zantrex and they tell me these inverters will work fine in the flooded cell mode with Lithium batteries with the following cavet. Charging will shut off at 90%. If on shore power you can trick it into a full charge by disconnecting the shore cord and plugging it back for an hour before you're ready to hit the road.
I found the Zantrex 240 AH lithium batteries at a good price. I'm assuming these are quality batteries??? Anyone have any comments on these batteries.
