My Turnigy Multistar ESC programming card allows me to select between LiXX and NiXX. While my Multirotor uses LiPos, I see that the low voltage cutoff setting for the ESC card can be set much lower if I select NiXX for the NiMH battery type. I am therefore tempted to select NiXX mode to take advantage of the lower cutoff voltage capabilities of the ESCs....... Anyone here able to help me with this decision before I configure all of my ESCs?
How timely is this post.
I am just playing around with my ESCs also at this time.
Mine were pre-Programmed by my dealer, but me being a nosey git wants to know exactly whats involved.
Program ESC's for multirotors as ESC's are usually designed/pre-programmed for airplanes:
Brake Setting = OFF
Battery Type = NiMh
Low Voltage Protection = SOFT CUTOFF
Low Voltage Protection Threshold (if available) = OFF or 0
Startup Mode = NORMAL
Timing = HIGH - See more at: http://flitetest.com/articles/keep_your_multi_rotor_safe_#sthash.Qoeo4daQ.dpuf
Maybe someone can shed a bit more light on exactly which way they should be programmed?
And any tips/tricks they have also discovered in the past.
Different ESCs and programming cards may offer slightly different functions but in general there is much in common. I am using the Turnigy Multistar 22 pole 420KV motors and the Turnigy Multistar programming card as follows:

IMHO these are my choices and reasoning.
Batt Type = NiXX for NiMh extra low cutoff voltage ranges.
Cutoff voltage = low as possible or zero if that is an option hence select NiMH or NiXX (don't want escs favoring battery protection on a Multirotor)
Brake = off (some acrobatic MRs might prefer to use braking function..... not good for smooth and slow aerial video work with expensive cameras onboard)
Timing = high (RC radios capable of handling high speed servos need faster timing and ESCs need to respond asap).
Cutoff type is = slow down (want motors to slow down gradually - no big surprises)
and startup = high (need MR to get in to the air quickly and safely.... not sluggish which can lead to tipping over etc.,)
