GPRS Shield Maximum Voltage

Hello, I would like to power my GPRS Shield with a 7.2V battery, since I use the 5V
of the seeeduino for another component.
I’m wondering if the GPRS Shield could be damaged ?
Thanks in advance for your help.

Sorry for response you so late.
The GPRS Shield could work only in 5V. You can power GPRS Shield by plugging the Lipo rider if you don’t use the seeeduino’s power.
