I have my Tab360 hooked to a generator trying to fill a lithium 460Ah Epoch battery. When it starts charging with either a 30amp or 15amp hookup the battery will have a high reading to start. This indicates it is getting a good Amp/Voltage from the generator. Within a few minutes it has stepped down from 20 amps to 3-4amps . The dealer is trying to say this is normal but I am not buying it. He is saying the converter is not a battery charger and will give minimal voltage around 12v. But if that were true why does my battery and shunt show it starting at 20amps and high voltage and then stepping down wouldn't it always be low.
While I can buy that a true battery charger do I really need one to charge at any acceptable rate.
If I do need one can I permanently mount one so I don't have to dig open the housing to get to the battery

The WFCO Power Center does have a Battery Charger feature/function. Read the operational section of the manual for a better overview of how the WFCO works.
For now, here is the Manual section on how to read the LEDs to get an idea of which operational state your Power Center is in . . .
The LEDs are not super easy to see. They are located at the bottom end of the 12VDC Fuse Panel and to the panel's left side, somewhat blocked by the metal face plate. (The LEDs are on the Convertor board not the fuse panel itself)

Yes, a charger is fairly easy to hook up. The AC side is connected to 110V and the DC side is connected to a bus bar (connected to battery) for the 12V pos. and neg. Many are bluetooth controlled so you can turn them ON/OFF via an app. You can have multiple chargers so there is no need to disable or turn off the WFCO charger, but that is also easy to do by disconnecting the wires in the WFCO for the charger. You can hide the charger behind anything so it's out of view. I installed a new 110V outlet near the battery for the charger AC plug. You could also put in a new AC breaker in your WFCO so it's on a dedicated circuit and turn it OFF/On via the breaker.

I will check the state LEDs as confirmed above. I feel that this will indicate it is not fast charging. I know when I first did this I was getting constant 20ah while in bulk. It seems that this has changed.
Thanks All
The red light comes on blinking for maybe a minute then goes out. It will steadily move down the charging amps until it reaches 2-3 amps.
So reading up on it AD stands for AutoDetect which I take to mean it is supposed to figure out what type of battery and that there are no switches for me. That is unfortunate and means another trip to the dealer assuming I can convince him it is not Auto Dectecting
If it was my rig - - -
I'd contact WFCO Directly for the PCB Jumper that forces the "AD" into Li-Ion mode
( if enough folks do so maybe they will add a switch )
It is also doable to just install a pull-down resistor yourself if you have basic electronics soldering skills. There are several threads on this forum discussing how the jumper works and it's location on the PCB.
