Replace Converter/Charger Section of Parallax 8355 For Lithium Batteries
Updated 08/12/2025 | Published 03/11/2021
Question:
Do you have a recommendation regarding an upgrade to my Parallax P.S. Model 8355 to a Converter Charger that supports an SOK SV12V206 LiFePO4 RV house battery? The SOK SV12V206 spec sheet shows recommended/max charge currents of 40A/50A.

The Progressive Dynamics # PD4655LIV is exactly what you need. No need to replace the entire power center, just the converter/charger section. The # PD4655LIV will provide 55 amp charging for your lithium battery(s).
