Customer Reviews for VEVOR WF-8955-AD-MBA Main Board Assembly, 55 Amp, Three-Stage RV Power Converter Replacement Unit, Compatible with Lithium Lead Acid Battery, Fit for WF-8955, Parallax 7145 & 7145 Series Converters

This VEVOR WF-8955-AD works way better than the original WFCO WF-8955-AD-MBA that I originally had in my RV. I was unable to get my original WFCO WF-8955-AD to auto detect my 200ah Lithium battery banks. Tried draining the batteries, tried power the converter charger on and off, tried putting a much of a load as I can on the lithium battery, but to no avail. The WFCO WF-8955-AD will not auto detect my Lithium. I replaced it with this VEVOR WF-8955-AD. It was a real simple replacement. I flipped the switch to Lithium and everything works as expected. Saved my time and money.

Great prise great product. Exact fit this item shipped fast and was packaged nice. The directions were easy to read and it even came with a jewelers screwdriver to fine tune the DC output.

From what I can tell I didn't need it anyway I fixed the other one but the product looks like it it was identical to what I needed the workmanship look good and when I use it I hope it still works I want to thank you for your help and your prompt getting it to me

Replaced the lead acid battery with a lithium battery, but the old charger would only charge it to 80%. This dropped right in my camper and now the battery charges to 100%.

Fit perfectly. Works good. .

I upgraded my RV electrical system to LiFePO4 batteries on a 2019 Thor Four Winds 22E with Chevy Chassis and this is something I had to change to charge the new batteries. The RV came with basic Acid batteries and all the charge controller and the Converter had to be changed out. There will be more challenges I think, but this Converter works perfect. I connected it as per instructions, set the switch to Li and it worked well. On shore power I have the batteries topped off all the time. I installed 100 AH LiFePO4 for the chassis as well, 100 AH in the house battery of the same chemistry. I DIY'd a Shore Power Solar generator with a 200 AH LiFePO4 base battery with a VEVOR 3500 Watt Pure Sine Wave Power Inverter where I can connect to a 30 Amp connector supplying my whole RV with healthy 30 Amp 120 Volts Shore Power, with that I can run the air conditioner for limited time as it allows from a 200 Watt panel feeding back into the box. As financials will permit, I'll parallel connect an 8000 Watts 1000 Farad Super capacitor to this system (about a $1 per Farad cost) to be able to run the Air conditioner and more appliances in a nice sunny day with only a 200 Watts panel. Super Capacitors are fast charging and fast discharging energy storage units. With that there will be enough energy to start the air conditioner as well, without needing to run the gasoline generator. I built another smaller solar generator too with a 100 AH LiFePO4 battery parallel connected with a 667 Watts Super Capacitor combined with a VEVOR 2500 Watt Pure Sine Wave Power Inverter for daily cooking with electricity and for running the fridge. These 2 generators with a combined 500 AH battery bank 400 Watts Solar panels will enable me to live off grid for a while.

Easy to install and works great. Nice and quiet when not under heavy load. Nice indicator light to know it's on

THE PRODUCT IS GOOD CUST SERVICE IS TERRIBLE i would buy again but not contact cust service the respnse from them took two days and then was not a technical person

Works great. Even at 55 amp output it gets barely warm. Used it as replacement for a 35 amp unit charging a 120 amp/hrs lifepo4.

Bon produit et je comme lai pour accompagner plus tard en cas de besoin et j'espère qu'il fera le travail à merveille Merci
