I would guess it is possible that the computer may be seeing battery voltage that is high due to the lithium bank but I do not know enough about that to say one way or the other.
I can suggest to keep the switch you are using to combine the banks in the position that keeps the bank separate when the engine is running. That way the engine alternator and computer will not be affected by the lithiums because of the isolators but the alternator will still charge both banks. Resetting that error code becomes the next problem. If you can reset it, keep that switch in the separation position and maybe the error code will not return.
