The protector concentrates three functions in one unit:
Deep discharge supervision and protection.
Battery voltage measurement.
Abnormal throttle signal supervision and lose-control protection.
Size: 32mm(L) * 18mm(W) * 9mm(H) Weight: 5g
Battery Type: 2 cells lithium battery pack Low voltage cut-off threshold for each battery unit: 2.6V, 2.85 or 3.1V.
(Correspondingly, the total threshold for a 2 cells LiPo battery pack is 5.2V, 5.7V or 6.2V) Tolerance: 0.05V
Deep discharge supervision and protection:
The protector provides reliable protection from the "deadly" deep discharge for your precious Li-Po battery cells. It can monitor not only the total voltage of whole battery pack but also the voltage of each cell, so it can prevent the weakest cell from being damaged earlier than the other cell in the same battery pack. When the voltage is lower than the threshold, the protector will stop the motor.
There are 3 LEDs on the protector to indicate the voltage of your battery pack.
When the voltage is more than 7.8V, all of these 3 LEDs light;
When the voltage is between 7.8V to 7.0V, #2 and #3 LEDs light;
When the voltage is between 7.0V to the pre-setting threshold, only #3 LED lights;
When the voltage is lower than the pre-setting threshold, none of these LEDs lights;
Abnormal throttle signal supervision and lose-control protection:
The protector will continuously monitor the throttle signal. When the throttle signal from receiver is normal, the protector will just transfer this signal to the speed controller (Pass this signal to the speed controller without any modification). If the throttle signal from receiver is abnormal, the protector will automatically lock the signal to the controller at a special level you preset (We call it "Protect Point").
