Low Voltage Cut-Off

The function mainly prevents the lithium battery pack from over discharging. The ESC detects the battery’s voltage at any time, if the voltage is lower than the threshold for 2 seconds, the output power will be reduced 70%, after 10 seconds the output power will be completely shut off and the red LED flashes in such a way: “☆-☆-, ☆-☆-, ☆-☆-”. Please stop your car at the track side as soon as possible to avoid obstructing other racing cars.
Please note that the cutoff threshold is basically calculated for each LITHIUM (Lipo) battery cell, so for NiMH battery packs, if the voltage of the whole NiMH battery pack is higher than 9.0V, it will be considered as a 3 cells lithium battery pack; If it is lower than 9.0V, it will be considered as a 2 cells lithium battery pack. For example, a NiMH battery pack is 8.0V, and the threshold is set to 2.6V/Cell, so it will be considered as a 2 cells lithium battery pack, and the low-voltage cut-off threshold for this NiMH battery pack is 2.6*2=5.2V.
There are 6 preset options for this programmable item. You can customize the cutoff threshold by using an advanced LCD Program Box (Optional equipment) to trim it with a step of 0.1V, so it will be more suitable for all kinds of batteries (NiMH, NiCd, Li-ion, Lipo, LFP, etc).
