How to connect LoNet 808 with Arduino

I hace bought a LoNet 808 - Mini GSM/GPRS + GPS Breakout
with a battery.

I need help. I don't know how to connect the LoNet to the Arduino. Both (the LoNet and the Arduino) must use the electricity from the battery.

I also don't know if this board would work and I don't know how to use it.

Both (the LoNet and the Arduino) must use the electricity from the battery.

If you mean the on board battery then good luck with that. It is merely for backup purposes, ie keeping the clock running.

The GSM/GPRS devices draw up to 2 amps when transmitting, and this includes handshaking with the network.

I supposed that I coul connecta a LiPo battery to de LoNet. Then connect this

to the battery, and finally connect the Arduino to the
