Ratings & Reviews
I have shopped (a lot)via the net for this converter as a replacement. My previous one is not defective but does not have the "voltage bump" for Lithium Batteries. etrailer was the only one that had in the description (picture) the confirmation that it was lithium ready.
The switch was very easy, even though the instructions from the manufacturer are very generic.
Shipment to Canada was straightforward.
etrailer - easy to work with, absolute kindness and responsive people not to mention knowledgeable about their products they represent. Have never had an item we purchased that was defective or incorrect. Best advise I can give is pick up the phone and talk to the folks at etrailer before ordering and chances are it will not have to be returned due “wrong part ordered” doesn’t hurt to talk about your project as these guys have already been there and could provide valuable information.

Shipping was quick and the price was good. Easy way to convert my older camper to Lithium power. Thanks
Services were fast .
Allowed me to switch from a heavy lead acid battery to lithium. Easy to install and works perfectly.
Perfect fit. Took me 5 min.
The people I talked to were absolutely awesome and speak my language clearly! Super helpful. I will continue to do business with them!
Easy, direct install
Product matched the description perfectly. Fixed the buzzing noise which I’m sure would’ve been a future problem. Only took about 20 minutes to replace.
I wanted to use lithium batteries but my old progressive dynamics power center wouldn't charge lithium. So I bought this one and it was easy to swap out and works as expected.
Purchased This replacement converter section so it would be compatible with Lithium batteries. It was easy to install and works as intended. e trailer is my go to when I need something for my RV
Simple replacement for a noisy converter in a 2015 Lance camper. Easier to install then replacing the entire circuit box.
Fast processing and offering UPS now for delivery which is fantastic. Very good purchase process this time around.
Excellent advisor!!! Part came faster then excepted! HIGHLY RECOMMEND using E-Trailer
Thanks for your quick delivery on the PD4045CSV. My installation saved me $330 + what the local RV dealer would have overcharged me to replace it. Thanks to Progressive Dynamics and e-trailer for the easy to replace part.

The installation was easy and worked well. I have since sold my JAYCO camper so I am no longer using it. The new owner has not contacted me with any issues.

Work great. Install was easy and the instructions were clear.
Thought I was getting a different model that would say 55M and since it wasn't in stock for another two weeks or more before it could be shipped. It was suggested that I buy this one. And when I received it, I realized it's the wrong one from my charger, so it wouldn't fit. It's too small, it would fit in the hole, but I didn't want to cluge it in, so I exchanged it for the correct one otherwise it looked perfectly, normal and don't see anything wrong with it.But I just didn't use.
Perfect fix for my noisy converter. FINALLY peace and quiet!!! Thanks Etrailer.com!!!!
Perfect replacement converter for the PD4045KA in my 2016 Lance 865 camper so that I can properly charge lithium battery. Easy install. Tested and it sends proper voltage (14.4V) for lithium battery. Note: It has a switch on the board that must be set to LI position. Installation videos and instructions are easily found on the Internet.
Perfect replacement
As described and fast shipping
Item was in new condition as described and easy to install Shipping was really quick.Communications was great.
Haven't installed the converter yet, but staff assistance, information, and shipping have all been excellent!
I needed this upgraded board to charge lithium batteries. This unit has a dip switch that allows charging of LA or LI batteries.
The installation was very straightforward, the hardest part was lying on the floor to access the power distribution system.
Have to activated it yet, waiting for my battery to arrive.
Remember, if switching from LA to LI, you need to change the on board trickle charger ( this unit) and the solar charge controller.

After over a year and substantial use, the board is holding up well.
Direct replacement for older model that did not have a switch to select charging profile, Lead Acid or LiFePo2. LiFePo2 battery has been a game changer for my 2015 Lance 1575. Very happy to find the exact right part at etrailer.com.

Used it between April and November 2025. It works properly in my camper. On one occasion after several days of bad weather. When I finally had shore power, I heard the cooling fan work for one rare occasion I guess the battery charger was sucking up more power. It is not very loud or annoying at all. It was just that quiet where I was, that I could hear it.
