The onboard OEM charger, I dont know. You don't mean the converter, do you? If you mean a non OEM charger I would install, I dont have one. All the charging now comes from alternator, generator/converter, shore power and later added MPPT solar controller. As far as I know, I don't know of a specific charger unit.
By the way, my setup requires me to physically plug the big shore power plug into a big outlet (powered by gas generator, obviously) in the same compartment in the back, probably common. If not plugged in the generator wont power or charge anything. Thats where I was hoping to plug in the extension cord from the inverter to have boondock house power. Especially if I can find a way to shut off the converter/charger going to the battery while wired this way. At the breaker box perhaps? But again nothing is labled in there, so I need to find WFCO (breaker box maker) model specs and hope they match.
Here are the spec sheets I got from Lithpower:
that i said oem charger is the same as converter.
i am not familiar with your rv, you might want to call the manufacturer or a dealer to find out what kind of converter/inverter was installed from the factory. in my mind, most of the rvs have a charger/inverter combo with ats installed.
i briefly went over the tech docs you attached; the first one shows the bms parameters which is doing the exact same thing as what i described on my previous post. it's just a basic bms plus the li cells.
the second doc appears talking about 3.2v 3.5ah cells, not the one at 3.2v with 150ah in the box i guess. fyi, my cells either from calb or winston, are 3.2v 100ah each. they even have larger ones like 3.2v 200ah or 400ah each. i assume yours should be 3.2v 150ah each.
