Replacement Converter for Lithium Battery Upgrade  

I upgraded my truck camper to 800ah LiFePO4 batteries and had to replace the existing PD converter. The difference was amazing. Even at a almost complete drain of the batteries the new converter worked perfectly at full capacity to charge the batteries. I works perfectly in conjunction with the solar and DC-DC charging systems when trying to do a fast charge The existing PD worked flawlessly for 12 years until the upgrade and I expect nothing less from the new system

Hi David, I also replaced a P9260C with a P9360 converter in my rig in Early 2025 to accommodate the 400Ah of lithium I used to replace 2 golf cart batteries. As was mentioned by at least one other person. when you install it, be sure you can access the small hole in the side of the converter to select the battery type. The LED that indicates the setting is not too easy to see on an angle and to me, the green and blue are too close of colors. The only CON to the installation, and this applies to my particular set up and not the product itself, is the RV manufacturer (Northwood) has the convert in the rear of the rig, near the AC/DC distribution panel. There are 6 gauge wires from the converter to the front of the RV, eventually ending up at the batteries. The run of wire is approximately 30 feet. When I checked the voltage at the converter, it was the appropriate 14.1 that lithium batteries need to get to 100% charge. At the batteries, the voltage was about 13.8 meaning the batteries would not see the appropriate voltage due to voltage drop in the wires. So, in my case I ended up having to make a choice. 1. install an additional battery charger close to the batteries that would bring them up to 14.1, or 2. take the plunge into a inverter charger from Victron to supply the what the battery needed and provide 120V AC to the RV from the batteries. My choice was number 2. The PD9360 is still installed in the RV, but it's unplugged (disconnected from the AC). In the unlikely event the inverter converter dies, I can plug the converter in again and still have dc power that will run the DC items in the rig and charge the batteries to about 95%. Unfortunately for me, it was an expensive converter swap that I'm not using. I've also had no luck locally, in selling the old converter.

Greetings David. I replaced the converter original to the one in our Grand Design Reflection travel trailer with the PD 9300 series when I installed a 300 Ah lithium iron battery. So far, so good. It does seem much quieter than the one replaced and seems to be built like a concrete block instead of the plastic stuff out there from overseas. I also purchased a 2 Kw inverter from Progressive Dynamics, and it too is built like a good ol' fashioned American car from the 50s. Have not installed it yet, though, but look forward to the upgrade.

Purchased the Progressive Dynamics 9300 Series RV Converter Charger - 12V - 60A after the WFCO kept losing the auto select for Lithium. With 2 100AH LiFepo4 batteries it performs flawlessly. Just set the converter to Lithium. Just got a new 5th wheel and was glad to see the PD Distribution Box. Very simple install, positive, negative, ground and 120v plug into the receptacle in the distribution box.
