I am using an Arduino WiFi Rev 2. Would it be possible to use two 9V batteries in parallel to power the board via the power port? I want to increase the overall current to increase battery life thus using two batteries in parallel instead of one.

We do hope you do not think this is a battery usable for powering an Arduino project:
