to change from lipo to nich and visa versa, you will need to plug in the battery and the Led will flach for 2 seconds to indicate the selected battery type. During this time, you can then select desired battery type. When you have the selected battery type, press the button again and the Led will flash again for 2 seconds letting you know it is excepted. Red light indicates lipo and green indicates nich.
Straight from the owners manuel from my xxx-sct.
Hope this helps and see you sunday.
