The protector concentrates three functions in one unit:
-Deep discharge supervision and protection
-Battery voltage measurement
-Abnormal throttle signal supervision and lose-control protection
1 Specification
1.1 Size: 32mm(L) * 18mm(W) * 9mm(H)
1.2 Weight: 5g
1.3 Battery Type: 2 cells lithium battery pack
1.4 Low voltage cut-off threshold for each battery unit: 2.6V, 2.85 or 3.1V.
(Correspondingly, the total threshold for a 2 cells Li-Po battery pack is 5.2V, 5.7V or 6.2V)
1.5 Tolerance: 0.05V
2 Features
2.1 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.
2.2 Voltage measurement
There are 3 LEDs on the protector to indicate the voltage of your battery pack.
------------------------------------------------------------------------
#1 LED(Red) #2 LED(Green) #3 LED(Green) LEDs in Group A
------------------------------------------------------------------------
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;
2.3 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"). * Note: This function is only valid for AM, FM/PPM receiver, not valid for PCM receiver.
