Lipo Cutoff setting question

[SpEEdyBL]

The main reason people don't use it is because the cutoff is two low. CASTLE, MAKE IT 3.2 VOLTS INSTEAD OF 3.0 IN THE NEXT VERSION OF CASTLE LINK! Or adjustable by the user.

Well, we will be adding an adjust to a future version of the software, so that the cutoff threshold can be changed.

As it is, the cutoff is closer to 3.1V than 3.0V right now, and Lipo chemistry doesn't actually start any damage until a cell hits about 2.4V -- so there isn't any problem with using 3.0V as a cutoff.

And yes, the auto-lipo mode assumes that the batteries are at full charge. HOWEVER, the Monster controller ALSO beeps back the number of cells to the user -- so the user can verify that the number of detected cells is correct. (you will hear the normal power-up beep, followed by beeps for the number of detected cells, and then followed by the arming tones.)

Glad to hear this will be a option in the future. Very welcome update.

As for the cells not being damaged.... tell that to my puffed flightpower 4350 25c pack that I puffed in my buggy using the auto lipo setting. Since switching to maual setting of 3.2v/cell I have not had another problem. The auto setting as it currently is allows the battery to drain to low and stresses the cells. This is my opinion.
