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.

Two 9V in Parallel Power Supply

Could you elaborate on this, please? Is it something specific for the Arduino WiFi Rev 2? How about the regular Uno R3?

P.S. this topic has made it into google results already, lol.
