Not sure if this in the correct bit, but here goes. Have just got an ESC which has adjustable cut off voltage. It is for LiPos and Nimh cells and it explains how to adjust the cut off point at various values, expressed as a percentage of the fully charged battery, ie, 65%,70% or 75%. I am going to use it with a 6 cell NiMh pack, 1300 Mamp, what value should I set it at so as not to deep discharge the Pack? I would prefer to err on the side of safety rather than get the last bit from the pack. Are these values for LiPos or do they also refer to NiMhs? Like to know from you clever  lot!!

First a warning! - Be very careful using these ESCs unless you know the battery is fully charged (I killed a 3s 2200mAh LiPo by not understanding the instructions properly, used a part discharged pack and reduced the pack voltage to around 2.7v per cell )

Okay then, the way these ESC determine the LVC is by measuring the voltage when you connect it - and then calculate the %age of the 'connection' voltage - when the pack voltage drops to this setting it will shut off power to the motor part of the esc but retain power to the radio.  Many can be 'cycled' to provide 'get me home' power.

Settings I recommend are;

LiPo batteries - set to 75% (4.1v x 75% = 3.025v)

NiMh batteries - set to 65% (1.55v x 65% = 1.0075v) - if you want to be extra safe use the 70% setting for NiMh packs if not 'hot of the charger.

for nimhs most esc I have seen Castle Jeti and a few other's just  turn it off or set at 5v as there isn't the problem if you are NOT using LiPo's

this may help to give you an idea.  what esc is it ?

The ESC is from Conrad Electronics, it is the MC-20A sold under their Modelcraft label. Obviously made for them in China. The brake function can be switched on or off and it is for 6 to10 NiMhs or 2 to4 Lipos.  BEC is 5 volts, 2 amps. Max power 20 A. Short burst  (10 seconds) 40 Amps. Not for me I think!! Thanks for the tips so far, will do as you say, thanks so much.
