11.1 v, 1200 mah , 15 C should give you about 1500 rounds then you must change a new one and stop using the lipo when you notice your roof get slow because discharge the lipo under 3 v will be cause to fire.
You should get a lipo lower voltage detector to test the voltage of Lipo because Lipo battery never discharge lower than 3 v.
