Seeeduino GPRS

Hello, I’d like to develop a project with Seeduino GPRS and I have some question regarding power: the source where it will be attached is 12V 1A, is it enough for peak requests during transmission?
Is it possible to attach a LiPo battery as source power backup and is the card able to manage the battery (charge and switch when needed, etc)? Where have I to connect to?
Thank you in advance for your help.


I recomend you a 12V 2A source.

I have check it, and if you want to receive a call o call to anybody, you have to put a good power source.
