WFCO WF-8955-AD-MBA Main Board Assembly for WF-8900-AD Series Power Center - 55 Amp , Black

I wanted to upgrade from our old single lead acid battery to dual lithium batteries on my 2014 model Lance travel trailer. The original converter from a decade ago would not support the correct voltage and charging profile for lithium batteries.I'd read online some people had problems getting these converters to properly sense lithium batteries and would not automatically switch over. But I read that WFCO had made some software changes to these units and people were getting good results, so I decided to buy this one.Install was easy. You remove the old converter, disconnect and reconnect a few wires and it's done. It sensed my lithium batteries within a few minutes and has worked perfectly ever since.We also have rooftop solar on our camper as well. Our trips have been a mix of hooked-up with 30A electric and off grid. When hooked up, we run the converter and it works as expected. Sometimes off grid we find ourselves with days of rain or a very shady campsite and the solar does not keep up. In that case we have a built in 7200 watt generator in my truck and I can plug in and recharge the batteries with this converter. It does what's expected, there's nothing more I can ask. According to my shunt the batteries top up just fine and the voltages are as expected.TL;DR: I don't regret the purchase at all. We've used our camper extensively in the six months since installing it and the converter works without fail.

I didn't time the install, but approximately 20 minutes. Fast and easy and a life saver.

I needed to upgrade to use my lithum-ion batteries. It was easy to install and works great keeping my batteries charged.

Product was used in a 2016 Forest River Microlite. Wiring was identical and it fit in the space provided.Working fine.

Simple replacement for the original. Super simple swap, connected and started working like a charm. Compared to what the RV dealer wanted this was 15 minutes of work and saved us over $300 by doing it ourselves.

Swapped out older model when upgrading to lithium batteries. Had one issue with the fan not running correctly and thus, not charging the batteries when hooked up to shore power or generator. Seemed to be due to a pinched wire or loose connection. Checked the connections and carefully reinstalled and now is working perfectly.

The main board assembly on the WFCO electrical panel for our RV travel trailer went out some years ago. In the meantime the battery technology had changed quite a bit. This replacement unit is also an upgrade which will automatically detect and charge lithium batteries as well as lead-acid batteries. With the help of a youtube instruction video, installation took less than 15 minutes.

As a repairman. I could not find this component at my local store. Was lucky to find it on Amazon. I purchased two. First time sent only one. I repeatedly confirmed that the package delivered was only one. Because we are usually busy. There is a habit of receiving packages. Is that need this accessory customer comes will open the package with the customer. Let my customers know the components are brand new. And it is from Amazon. The package was delivered for ten days before I realized there was only one delivery. I contacted the seller immediately. He expressed that he could send me another one. Thank you very much. This service deserves 5 stars. The product was easy to install. Because I know how to repair. The installation also solved my client's problem without any problem. Worth recommending.

My daughter bought a travel trailer and then discovered that the batteries weren't charging and the fridge didn't work if the batteries dropped below 12.8V even when plugged into shore power.The fellow she purchased it from must have charged the batteries before she viewed it so the fridge worked. He claimed he was a mechanical engineer and it appears he decided the solution was a solar panel, controller and inverter which he had not yet installed.I quickly identified the problem as the control board. This is OEM replacement however is an upgrade, to identify and charge lithium batteries as well as LA. It took less than 10 minutes to replace it and her system works perfectly now. Through Amazon it was about $200 cheaper than the RV dealer price.Now we just have to install the nice solar charger and she is ready for anything.

This unit fit perfectly in my Wafco WF1855AN main panel in our travel trailer. Only 5 wires to connect and 2 screws to remove/install. Saved me a lot of money by being able to install it myself. It’s only been installed for a few days but everything seems to be working very well. I’m very happy with this unit and would recommend it.

Muy buen producto, muy fácil de instalar

Excellent product. It was fairly easy to install.

I used this converter in my travel trailer. When it was plugged in the battery would not charge and everything eventually went completely dead. I took off the cover plate for the converter and fuse panel. The id number was there and I matched it up on Amazon. It arrived very quickly and only took about 25 minutes to install. Very easy, but be careful with the plastic parts for the fuse panel. It is very brittle. So far everything works very well.
