This article/video is for entertainment and educational purposes and should not be taken as instructional. Doing it yourself could cause you serious injury or death and may void your RV warranty and insurance. The following installation should be performed by a qualified RV technician or electrician. It’s just a matter of swapping the wires from one module to the newer version.ĭisclaimer: Working with electricity is dangerous. Installation of the new WFCO Auto-Detect converter charger is reasonably straightforward for anyone who knows electrical circuits. Furthermore, the charging usually stalls when the lithium battery bank is at 53% capacity. At best, the average charging current is in the 10-15 amp range. A couple of years ago, I upgraded to lithium batteries and quickly found out the old WFCO lead-acid type converter charger was less than stellar at charging them. The OEM installed a WF-8955 WFCO power center which includes a 55 amp converter charger. I thought my ten-year-old Keystone Cougar trailer would be a great testbed. Once it detects which type, it adjusts its charging algorithms for the most efficient charging. It’s a power converter charger that can auto-detect whether the RV has lead-acid or lithium-type batteries installed. Recently WFCO Electronics contacted me and asked if I’d like to test and review a new product they are releasing.
