Sets the voltage at which the ESC lowers or removes power to the motor in order to either keep the battery at a safe minimum voltage (for LiPo batteries). The ESC monitors the battery voltage all the time, it will immediately reduce the power to 30% (in 3 seconds) and cut off the output 10 seconds later when the voltage goes below the cutoff threshold. The RED LED will flash a short, single flash that repeats (☆, ☆, ☆) to indicate the low-voltage cutoff protection is activated. Please set the “Cutoff Voltage” to “Disabled” or customize this item if you are using NiMH batteries.
Option 1: Disabled
The ESC does not cut the power off due to low voltage. We do not recommend using this option when you use any LiPo battery as you will irreversibly damage the product. You need to select this option when you are using a NiMH pack.
Option 2: Auto
The ESC will automatically calculate the corresponding cutoff voltage as per the number of LiPo cells it detects and the “3.3V/cell” rule. For example, if the ESC detects a 2S, then the cutoff voltage for the battery shall be 6.6V.
Option 3: Customized
The customized cutoff threshold is a voltage for the whole battery pack (adjustable from 3.0V to 11.1V). Please calculate the value as per the number of LiPo cells you are using. For example, when you use a 2S and you want the cutoff voltage for each cell is 2.8V, then you need to set this item to 5.6V.
