The LED program card is used for adjusting the setting on the SMD brushless combos.
1：Low Voltage Cut-Off: The function is mainly to prevent a lithium battery pack from over discharging. The Speed controller is delivered with a 3.1v cut off per cell for lithium batteries. This setting may mean that an early shut down is possible when using NIMH, Ni cad or other batteries.
(Setting can be changed with the LED Program card which is optional).
