Will this non-programmable ESC work for my Lipos?

I have an ESC that I want to use with my 2s 730mah TP lipo pack. It is a 10 amp, with a low voltage cutoff at 3.6v (but it's not programmable.) I should be able to use this amp and not have to worry about ruining the battery pack, shouldn't I?

Ive used nonprogramable escs with my lipos in the past. All you have to do is fly your plane for a few minutes with a timer keeping track. Land and check your votage and take off again. Do this til you batteries are close to the 3 volt per cell limit and you will know how long you can fly from now on. A cheap cooking timer with alarm works well.

3.6V is not high enough to rely on the LVC. For a 2s pack, the minimum recommended cutoff is 6.0V UNDER LOAD.

You can use it but like was said above, but do it by time and not the LVC. The voltage of your 2s pack should not go below about 6.6V by the time you get around to measuring it. That is because the voltage will bounce back up after you remove the load. I'd shoot for 6.8-6.9V after the pack has rested awhile.
