I installed five 170Ah LiFePO4's from BigBattery (

I installed them under my dinette seats. Originally I did not replace the Inverter but I did have to replace the Converter with a Progressive Dynamics PD9160ALV for charging lithium batteries. I also had to replace the BIM 160 with the LI-BIM 225.
This spring I upgraded the inverter to the Xantrex Freedom XC Pro 3000 Inverter / Charger. I also did some rewiring so I could use the Inverter to run any circuit in the coach... like one A/C unit or the microwave. I also decommissioned the PD9160ALV Converter in favor of using the Inverter / Charger because the Xantrex is far more configurable and more efficient for charging the batteries.
The lithium batteries start the generator just fine. I thought about contacting FireFly about an update for the AGS voltage settings but for my purposes the AGS works fine.
