You should get a lipo lower voltage detector to test the voltage of Lipo because Lipo battery never discharge lower than 3 v.

That is an incorrect/incomplete statement.
The level you need to stop at is dependent on the size of your pack.
You can not drop below a NOMINAL voltage of 3.0v PER CELL of your PACK, otherwise, you will encounter permanent damage to your pack, if not a fire.
That means, if you are running a 7.4v PACK, then you will have two CELLS in your pack, which means you can not drop below 6.0v.
If you are running an 11.1v PACK, then you will have three CELLS in your pack, which means you can not drop below a nominal voltage of 9.0v.
There are some Li-Po cells out there that do NOT carry a nominal voltage of 3.7 volts, but are 3.6volts instead, which would effectively create a 10.8v pack from three cells. These types of packs will also have slightly lower minimum discharge limits, AS WELL AS maximum charge limits! If you try to charge/peak a 3.6v cell as if it were a 3.7v cell, YOU WILL BLOW THE PACK UP AND POSSIBLY BURN YOUR HOUSE DOWN.
You need to know all of these differences when dealing with Li-Po.
