Need to replace the converter in my trailer. The converter model is WF-9865LiS. Input: 105-130VAC, 1260W. Output: 14.6VDC, 60ALI, 13.6VDC, 65ALA. What converter do you guys have that would be compatible?

Expert Reply:

To replace your WF-9865LIS converter I recommend the Progressive Dynamics 9300 Series RV Converter Charger # PD79RR. This converter is compatible with lead acid, AGM, and LiFePO4 batteries and has a 60 amp converter rating. It installs the same way so this will be an easy swap out of your current converter. I've attached the instructions below for mode selection so you can match the your battery type.

I have the WF-9865 1260W 13.6VDC 65AMP. I’m putting in the Li Time 12.8V 100AH smart battery 1280W, charging voltage 14.4V. I need a replacement for the WF-9865 that would be compatible with my Li Time and give optimal lithium charge and also stay with the current #6 wiring. Offers a constant 14.6?V single-stage lithium charging profile, built-in reverse polarity protection, thermal management, and filtered DC output to protect my battery’s BMS . My RV is a 2018 Highland Ridge Open Range Ultra Lite 2710RL if needed for reference.

@WayneE the Progressive Dynamics 9300 Series RV Converter Charger # PD79RR Kevin recommended would be the best option. It is lithium compatible, has an operating temperature range of 32°F to 122°F, and has reverse polarity protection.
