Absolute lifesaver.
Got quoted twice the price of this unit (with overnight shipping!) by a local rv repair shop, for the part only plus an unknown amount of labor!
Overall it took me just under two hours to replace the converter and panel, taking my time and double checking everything. The instructions are absolutely amazing and spot on.
It saved my trip and my batteries. It also prepares me for the future when I switch to Lithium batteries.
My only small complaint is that the new screws on the outer panel are now metal instead of brown, but I just decided to not look in that direction ever again.

Wow, sounds like you powered through that repair like a pro Mike! Not only did you save your trip, you’re ready for the next step with Lithium batteries, talk about amping up your RV game! As for those screws, like you said, you won't be looking while you're charging ahead!

Recently, my wife and I have been experiencing battery issues with our motorhome. Thanks to e-trailer, I was able to determine I was having a charge issue from my converter. I ordered the PD4645 and followed the instructions. In less than an hour, I was upgraded and the system was back in full operation. I especially like the multistage charging based on battery condition. Job well done by e-trailer once again. A special thanks to Neil for providing

Easy install and the replacement is working very well. However, not clear direction on lithium selection mode (it is not a switch but a tab that needs to be lifted off and moved to a new position). Install required a larger breaker and wire due to the added power of the charger compared to my old 45amp component. Knowing the possibility ahead of time would have been nice. Overall 2 days in I am happy with the unit’s performance and installation was way easier than I expected. I chose to replace the optional 12v panel.
The lithium selector location is in the second photo.

I am glad the installation was a breeze and it is working well for you. The Lithium selection should be a very small switch located around that second photo that needs to be flipped for that activation.

My 24 year old Parallax convertor caught fire and thankfully I was able to put it out quickly. This is a direct replacement for that model and has a lot of upgraded features. I had someone come install it for me as I had a stroke last year but it went right into the same spot and required no modifications. It came with a new DC board which switched right over and had a few extra spots for any additions. I also replaced my 5 year old batteries while we were at it. So far so far so good.

by: TS 10/01/2026

Replaced the original Magnetek converter with this one in less that 2 hours. Hardest thing was having to be on my knees most of that time as the unit is a couple of inches off the floor of the Casita. It would have been REALLY great if a printed installation manual would have been included but I watched one of the videos on the etrailer website and that was helpful.

by: GDubb 04/16/2026

I upgraded my 2002 Lance camper to a lithium battery, which required replacing the factory converter to properly support the new setup. This Progressive Dynamics unit arrived on time and was well-packaged.

Installation was straightforward and very manageable for a DIYer with basic skills. The unit comes preconfigured for AGM/lead-acid batteries, and switching to lithium only requires moving a small jumper over one pin. That process is simple in theory, but the jumper is mounted facing inward, which makes it a bit difficult to see and access. It would be an improvement if the manufacturer either oriented the jumper outward or, better yet, used a small external switch for battery type selection.

I also didn’t notice clear instructions included for changing the battery type. I already knew what to do from prior research, but first-time users might find that step confusing.

So far, the converter appears to be working as expected. I haven’t had the chance to test it under real camping conditions yet, as the camper is still at home, but initial performance has been solid.

I agree, it is indeed more difficult that it needs to be, but I'm very happy to hear that you figured it out. Good job!!

Fit like a glove in our 2010 casita replacing the original parallax 7500. Bought a new AGM battery and everything seems to be working fine. Ashley at etrailer was great to talk to and helped us get the right converter/charger(pd4645v). I’ve used this company before and they are excellent. The only reason I didn’t rate this experience five stars is we didn’t get manual/ instructions but we looked it up and utubed the installation process.

by: Tim 05/16/2022

This converter is excellent, as is the customer service. I had some confusion about the wiring, which the etrailer tech was not able to address. He gave me the manufacturer contact, who spotted my problem from a quick picture of my install. With that corrected, the unit has been running without issue for over a month now. I replaced a 32-year-old converter and the first thing I noticed is that the lights have gone from dim/depressing to bright and cheery. I'm so glad I bought this unit from etrailer rather than the one made in China from [online].
Picture 1 is what I took out; Picture 2 is the new unit.

Great item, it is exactly what I needed to power up the trailer. I phoned in and talked with Chris. I told him the unit I was looking at. His research got the unit I needed. Three days later it arrived. Upon opening the package I noticed there was no instructions or warranty paper work. I called again and Chris sent them by email. Great job Steve.

The replacement instructions I found online for it were perfect and complete with images. After testing the old one in my 1996 rv, I got up the nerve to change it out. The problem? I'm a 78 year old woman and the blankin' thing was on the floor under the dinette seat. So I spent the project time laying on the floor trying to see everything...Nailed it!

Perfect replacement and resolved my issues with battery not charging...

by: Benjamin 08/05/2025

Well I would probably like the converter if I knew it was charging correctly. Is it set for charging lead acid or my lithium ion battery? One can only guess. Mode button does what exactly? How do you know what mode it is in. I read some of the answers to these same questions asked by other customers and it seems as though nobody knows for sure. So you guys give me the number to Progressive Dynamics and when I call, it rings 10-15 times and goes to an automated voicemail. I left a message requesting information on how it works and nobody has returned my call. Kind of frustrating. I installed a different Progressive Dynamics converter in my travel lite camper 4 years ago that had a switch for either lead or Li. It’s a shame this one couldn’t have something so simple or come with directions on exactly how you operate it.

Hi Ben. The switch on the Progressive Dynamics Replacement Section # PD4645V will have "LI" and "WIZ". LI will be for the lithium iron batteries and WIZ will be for the lead acid batteries. It can be hard to see, but I included a link to a Q&A with a very clear picture you can check out.

It was a perfect swap for our old converter. We had it installed by a friend and it only took him about an hour he said to get it all hooked up start to finish. We are thankful for the help we received when we called in before purchasing.

Can I Swap Out the Converter Section of My Parallax 6345 so I can Charge My Lithium Batteries?
Hello again Daniel, The B-W (B-W Manufacturing / Parallax) 6300 Series Model 6345 is an older converter/charger unit designed primarily for lead-acid batteries, such as flooded or AGM deep cycle batteries. These older converters typically charge at a single-stage voltage (around 13.6V), which is not suitable for modern lithium iron phosphate (LiFePO4) batteries.

How To Switch The PD4645V Converter To Lithium Charging Profile
Hey Randy, thanks for getting in touch. The "switch" or "jumper" you are referring to is actually built-in as part of the # PD4645V converter, so there is nothing separate you need to order.

Since they didn't list the converter amperage rating on your panel you'll have to just choose the amperage your battery bank requires and then do a bit of investigative work to ensure that the wire gauge used for the converter is enough to handle the load for the new converter. Most of the options I'm seeing for the 7300 series are showing up as a 45 amp converter, which is pretty standard for most trailers.

30-amp Reverse Polarity Fuses Blowing on Camper Converter
Hey Debbie, Based on what you described, it does sound like an issue with the converter, especially since the appliances are working but the battery isn't charging. One thing to note, though, is that the 30-amp fuse is meant to blow in cases of reverse polarity. It's possible that the wiring on the 12V charging circuit is wired in reverse and it's blowing the fuse to protect the converter. Since you've confirmed the battery connections match the wiring diagram and the issue is also happening...

What To Check If Progressive Dynamics PD4645V Converter Fan Will Not Run
Hey Brody, thanks for reaching out. What you’re describing usually isn’t an inline fuse issue, those units don’t have a separate fuse just for the cooling fans. The fans are controlled off the converter board and only kick on when the unit gets warm enough or under load. That slight humming you’re hearing is likely the transformer, which tells you the converter is powered up, but the fans just aren’t being triggered or aren’t able to spin. First thing I’d check is whether the converter...

Which Replacement Converter Section for Magnetek 6345
Hey Terry, I know it's tempting to go up in amperage when replacing your converter section but the problem is that the wiring of your setup is probably not rated for the additional amperage so you would be going from a super easy and simple replacement with the part # PD4645V to having to go over the wiring and make sure everything could handle the additional amperage.
