In addition to the previous question:

I plan to use two of these UPS boards, stacked together whole having power input (12V 10A) power supply connected for most of the time.

The idea is to continue provide power to the 12V 4A motor, even when the power supply is disconnected.

Will this work? With the power input connected, if the output side is drawing 4A, it can still draw 4A from the power supply, right?
