Expert Reply:
The Progressive Dynamics Inteli-Power RV Converter and Battery Charger - Lithium - 12V - 45 Amps # PD9145ALV is designed for use with lithium batteries and will match the amperage of your WF-8845 converter charger.
Built for lithium batteries, this unit uses a higher output voltage than a typical converter charger, which provides a fast, complete charge. The charger also extends battery life since it utilizes the appropriate charging profile. Additionally, it's compatible with your battery's internal Battery Management System (BMS), which helps manage charging by monitoring the battery state and balancing cell voltage.
The system includes a number of safety features. It has a reverse polarity protection that will protect the converter if the battery is hooked up incorrectly. It has short circuit protection as well, which limits the current and reduces the output until the short has been fixed. Additionally, the converter will shut down if there is excessive voltage. The built-in cooling fan also removes excess heat from the unit and only operates during high loads.
