My 2019 PC 2552 which was built for the Hershey RV Show came with 2 Trojan 6v AGM batteries. The converter is built into a Progressive Dynamics Power Control Center Model PD4500. It is a 3 stage nonprogrammable unit with the following stages: Boost Mode 14.4 VDC for rapid charging, Normal Mode 13.6 VDC when batteries are in use but at or near full charge, and Storage Mode 13.2 VDC for batteries that are fully charged but haven't been used in the last 30 hours. Also when in the Storage Mode quote "the voltage will periodically increase to 14.4 VDC to help prevent sulfation of the battery plates".
The Trojan VRLA AGM battery spec sheet recommends that the charging voltage be between 14.1 and 14.7 VDC and the float voltage should be 13.5 VDC. It does not mention raising the voltage periodically to prevent sulfation.
Progressive recommends this converter for either wet cell or AGM batteries.
The power inverter is a separate Xantrex Pro Inverter model XM 1800.
So far everything is working very well.
