AspectSolar Energybar 225

Hi Folks:
I got hold of an Aspect Solar EnergyBar 225. It is a LifePO4 battery from a company that went out of business. It can be charged from AC with an little adapter that provides 15V 4A or by their solar Panel EP-60 that provided the same specs. Here is a detailed test of the battery (alto attached as a pdf) : https://static.dxengineering.com/glo...ergybar250.pdf
So, I'm trying to put the battery on a converted VAN for camping and I'm struggling to find a MPPT controller that would provide 15V. Could I ask for the more experienced people here for some suggestions on how can this setup look like? What controller should I get? I don't have any panels at this time, so a suggestion there would be welcomed too.
Thanks and appreciate the help.
P.S. Forgot to mention that the panel EP-60 is not available for buying, so I need to reverse engineer how it worked. It seems to shutdown at 5W. Here is a review of the panel: https://www.youtube.com/watch?v=N4TmqAb-dUc

That voltage is not a multiple of any LFP charging voltage that I am aware of. Perhaps the charging control is done after the 15 volt input. Can you access the insides to check what happens when plugged into the AC charger? Typical conservative LFP charging is about 3.5 volt per cell so 14 volts would be 4 cells in series.

Many of the Morningstar MPPT controllers (even the small ones) are programable for odd voltages,

Thanks guys for the suggestions. Unfortunately my son is traveling with the battery pack, so I can't open it to check. The last time I checked the battery was sealed, so I could really see which one they were connected. Regardless, the information I'm looking for is really how to provide a steady supply of 15Volts from a Solar panel. I'll check the MorningStar controllers to see their capabilities.
Thanks
