Charger for 3.7V 3600 mA Lipo battery

Hello, can someone help me find a charger for a lipo battery of 3600 mA, 3.7V?
I´m using it from a damaged chinese tablet with my electric imp.

Tonight the battery lost the remaining charge.
Now i need to charge it!!!
Dont know how to choose a charger…

I’m using this one, but Adafruit has them as we’ll.
