Di2 Failure - Help!

I have a full Shimano Ultegra di2 8050 groupset on my Trek Emonda that until this week was working flawlessly for the past 2 years.
I was on a road ride with a friend and suddenly the di2 died; no shifting, no lights on my junction box, just nothing. I came home and plugged it in to charge thinking my battery was dead; got the flashing red "battery error" light on my charger.
I plugged the junction into my computer and opened e-tube which identified all of the components including the battery.
I disassembled the bike and tried my spare junction B, along with trying all of my replacement di2 wires I have as spares. After changing all of these, the di2 is still completely unresponsive.
My thought it that it's a faulty battery but just wondering what you all think this could be?
