how to put voltage on Mega Sensor Shield v1.2

Good day

Using the Mega Sensor Shield v1.2 and I must be missing an information to supply voltage. Would someone know how I could attach my battery to the Mega Sensor Shield v1.2? The Mega 2560 has a Vin input so I could get my battery wire to Vin and Gnd but now that I have the Mega Sensor Shield v1.2 on top, I can not apply voltage to both the Mega and the Senor Shield.

I seem to have bought the last one from RobotShop. it is the DFRobot Sensor Shield v1.2

Thank you in advance for any help

According to, for v2 of the sensor shield you remove the jumper. Probably the same for the older version.
