The description states this is for lithium batteries, and yes it will charge lithium to a point, but only to about 80% capacity since lithium needs to be charged to about 14.6V. The description says 14.4 bulk charging but the sticker on the actual unit call out an output of 13.6V, and my meter shows it only putting out 13.5V. Also none of the markings on the unit, or anything in the manual say anything about lithium. Too bad, I was hoping to upgrade my RV with lithium and use this, but will now have to purchase a true lithium charger I guess. This should work fine for standard flooded cell batteries, but I would not use it for lithium. One other thing to point out is, as an electronics technician by trade, I have smelt a lot of burnt electronics, and this out of the box before even plugging it in smelt burnt. I don't know if that is because if testing done before it was shipped or what, but seems weird to me.

My recently purchased (at a good price) RV trailer came with a set of issues. One of those issues was that I was made aware of the converter being in need of replacement. I saw this and thought I’d give this one a shot, as it was in the range of what I’d expect for one of these.Nothing stood out on this unit right out of the box, but I didn’t expect anything different. It’s pretty much self-contained, so there is no way to tell but guess at its construction.Unfortunately, not long after I purchased the RV, the weather started getting nasty, and I covered it for the winter. It would be very difficult to get this thing installed for any true test. However, I did make an initial test-off of the trailer. I hooked this up to a somewhat depleted battery in an old lawn tractor. I knew the battery was still in good condition; it was installed new a year ago. But it got discharged from trying to start the tractor before I determined I would need to replace the carburetor (I have a newer tractor I use). I ran a 12-gauge extension from the battery to the converter. Before testing, I measured an initial reading of 12.1 volts on the battery—more or less fully drained. After maybe an hour or so (I really wasn’t paying attention to the time), the battery was reading 12.53 volts. So, it appears the converter was doing what it was supposed to do. I don’t know if that is a typical time frame to recharge, but the converter's job is to keep the battery at the proper level when in use. The real test will be to get this installed when the weather warms up.At this point, as it appeared to work well, I can't rate the converter anything less than a 5-star rating. However, in just a month or so, I'll put it to the real test. Should I feel it is necessary to downgrade, I'll edit this rating appropriately and add my findings!

This is a generic 65A power converter/battery charger for your RV DC power system. It has the same general layout and dimensions as my WF-9855 that is currently installed. I ordered this one as a backup/upgrade to it. It has a little higher output and also will charge lithium batteries so I can also upgrade the house battery too. This will have to wait for spring when the camper comes out of storage. The construction of the unit seems sound and installation should be a snap after I remove the RV access panel. Attach two wires, replace 4 mounting screws and plug in, that's it (kill power first!). The unit is quiet when plugged in on the bench and the fan comes on only under load. At half the price of the camper supply store, this seems like a good replacement/upgrade for your RV.
