I checked the owners manual and it repeatedly states that only 1 battery per channel shall be connected. I am just guessing but it might be part of the over current/battery safety algorithm. More than one battery in a bank and now the max current draw goes up, the time till full charge goes down and the bank resistance should also drop considerably. The unit will probably detect the "abnormal" conditions and then shutdown and display a battery fault.
