I am trying to make a Solar Powered Weather Station. I'm using the Arduino Fio, with a BMP180 and a DHT22 as the sensors. There are sleep modes activated with the Fio and the Xbee. It seems like the battery capacity requirements, after measuring, around about 664 mAh per day.
The Fio has a built in LiPo charger (MCP73831/2). Is this 3.7V 2000mAh battery safe to plug into the Fio as its battery source? Here is the datasheet from the link just provided. I'm not an engineer and I want to make sure that this is a safe device.
Once determining the correct battery, I will like to pair it with a solar panel.
Thanks for the help
