This 55-amp power center replaces your existing WFCO panel with an all-in-one converter charger and AC/DC distribution, providing more capacity for higher-draw systems along with multi-stage charging and automatic lithium detection.
Many RV owners upgrade their power center because the factory converter never charged batteries the way it should. Slow recovery times and batteries that never quite reach full are common signs. The WFCO Power Center is designed to fix that by using charging profiles matched to your battery type. Lead-acid batteries receive true 3-stage charging with higher voltage during bulk charging, then step down to normal, and trickle/float stages as they recover. Lithium batteries follow a two-stage process designed for faster, more consistent charging. The result is quicker recharge times and less day-to-day strain on your batteries, helping them last longer and perform more reliably.
Upgrading to lithium batteries is usually about better performance and long-term value, not extra complexity. This power center uses WFCO's Auto-Detect technology to recognize lithium or lead-acid batteries and apply the correct charging profile automatically. There are no switches to set and no settings to guess at. Once installed, it charges your batteries the way they are designed to be charged, helping you get the faster recovery, longer service life, and consistent performance that make lithium a worthwhile upgrade for your RV.
Instead of juggling separate components, the WFCO Power Center combines your AC breaker panel, DC fuse block, and converter into one integrated unit. This larger 55-amp design provides additional capacity for RVs running higher-demand equipment. With 10 AC circuits, and 11 DC circuits (including two 30-amp), it's well suited for appliances like slide-outs, refrigerators, and other high-draw systems, along with everyday outlets, lighting, and onboard electronics. The power center accepts standard residential breakers and automotive fuses (not included). You can check the product manual for recommended brands and styles, which are easy to find and purchase from most hardware or RV stores.
Electrical upgrades only bring peace of mind if they operate safely day after day. This power center is built with protections against overheating, over-current conditions, and reverse polarity connections, so a wiring mistake or heavy load doesn't turn into a bigger problem. LED indicator lights provide quick visual feedback to help identify power and fault conditions, making it easier to spot issues during troubleshooting. The cooling fan is designed to pull air in and exhaust it out the front of the unit, which helps move heat away from the components instead of letting it build up behind the panel. That matters in tight RV compartments where airflow is limited. If operating limits are ever exceeded, the system can shut itself down to protect the electronics. It's built-in safety that's reassuring when you're upgrading battery types or replacing an older converter that didn't manage heat nearly as well.
This WF-8955 power center is designed for RVs that need more electrical capacity than smaller factory-installed panels. It commonly replaces larger WFCO power centers and can also be used as an upgrade or replacement for other brands with similar layouts and load requirements. The rear mounting location for a transfer switch helps keep upgrades organized and accessible. Because this is a physically larger unit, it's important to verify cutout dimensions, wiring, and available space before installing. Some installations may require minor adjustments depending on the original setup. If you'd rather leave the job to a professional, you can use etrailer's installer locator to find a qualified shop near you and get help with installation.

Ratings & Reviews
New unit is install (me) and seems to be working fine.
Calibrating the unit to auto detect presently. I’ll let you know how that goes.
Just as advertised. Easy to install
It was plugged and play, works great so far.
My only issue is not knowing which wire goes to which black and white wire coming out of the wall
Perfect replacement for the original
Quick and easy install. Great shipping, too.
The product was a replacement and upgrade and worked perfectly. Siobhan did an excellent job helping me navigate the choices and got the converter delivered to me on time for me to install before my trip. Frosty beverages of choice for her! Thank you!!
Item arrived quickly and in good shape. Other than having to slightly increase the mounting location it installed easily and works great. I like how the cooling fan only runs when it's needed and not constantly like the old unit.
Does the job. Installation takes some time, but this is a direct replacement for the WF-8735 (non-lithium), so it's just a matter of disconnecting/reconnecting wires. Same exact size too, so it screws into the same holes. Only negative is this one has a small green light that always stays on, so if your converter is in a very visible location, it may annoy you at night.
Just what I needed and delivered quickly! Thanks Etrailer
I decided to upgrade the WFCO WF-8735 power converter in my 2020 Aliner Ranger 12 to enable charging my new LifePO4 battery. Staying with the same brand made the power converter upgrade easier. I spoke with eTrailer tech support prior to ordering and they answered all of my questions. The new WFCO power converter is now installed and everything is working as expected. I ordered this product from eTrailer because they had a reasonable price on this product combined with excellent telephone support if needed, as compared to other vendors that might sell it for a little less, but with no technical phone support.
Fast Delivery and exactly what I was looking for.
We received the part quickly it was fairly simple to install it took about an hour and fixed all of our issues we were having.
Direct replacement/upgrade to what i had. E-trailer is always tops.
Upgraded to the Newer Auto Detect (AD) unit. Was a quick install.
It was a perfect match to my old one! Just plug and play couldn't have been easier
Excellent product - fixed my electrical problem as my old converter stopped working.
A drop-in replacement for the original. The new converter auto detects the battery type and adapts the charging protocol. Now, my 190AH LiFePo battery fully charges.
The unit is good. Replacing the same size just gaining the lithium autodetect feature. WFCO gets 5 stars.
The low rating is because it took a week to arrive from etrailer. Despite paying for and requesting UPS shipping, somehow it was sent USPS which likes to send packages on tours of the country. So if you really need it rapidly like their estimated arrival time states, there is no way to know if it will arrive even close to that time even if you select and pay for the premium method.
This is a great unit! I bought this WF86FR to replace replace my old WFCO system in my 2010 Nomad Trailer. My old system still worked (which says a lot about WFCO quality), but I am replacing the old system so I can convert to Lithium batteries. This WF86FR auto detects Lithium batteries for the correct charging profile, which is really nice! The new unit was a perfect fit, same dimensions as the old unit. By comparison, the new unit appears to have the same quality as the old one. In addition, the wiring schematic was very easy to follow. I had over 30 wires from my trailer and was able to complete re-wiring and system checks in less than an hour. I waited to post this review until I could run the unit for 2 weeks first. No Issues! Everything works great! Also, I really like e-trailer (unlike Amazon, if you have a problem there is someone you can call!) e-trailer posts all the information you need and are very helpful. I have previously utilized e-trailer for some of my commercial trailer projects and have been very happy.
