What pins to use to externally power an Arduino Fio (without battery) I need to power an enclosed Arduino Fio project with 12V. The intention is not to attach a battery because there is no need as this is a fixed installation with a 12V DC available (for a pair of relays which will be controlled by the Fio). 

My question is what Pins should I use. The Fio page (https://www.arduino.cc/en/Main/ArduinoBoardFio) on the Arduino web site says...

Input Voltage   3.35 -12 V
Input Voltage for Charge    3.7 - 7 V

Unfortunately, there is no indication what pins these specs refer to. I assume that the "Input Voltage for Charge" refers to the mini-USB port and unlike other Arduino boards, there is no Vin pin to supply the board externally. Looking at the board layout on the same web page, I think the only possible option is via the two pins in parallel to the battery port which I suppose are then going into the voltage regulator on the board. 

Any comments or suggestions? Has anyone done something similar?
I used the external switch input JP7-1 for 12v, any GND hole, and make sure the switch is off.  This bypasses the charge circuit which doesn't like 12v.
