Battery power detection

The cooler box has the function of current detection of the battery voltage when the cooler box is switched on and the voltages below correspond to the following electrical quantity icons.

NO.  12V voltage 24V voltage Power display
0 U≤9.5 U≤21.2
1 9.6≤U≤10.7 21.3≤U≤22.2
2 10.8≤U≤11.2 22.3≤U≤24.5
3 11.3≤U≤11.8 24.6≤U≤25.3

Battery check

  1. Battery protection function for the cooler with three-class battery protection function, can automatically check the battery voltage of the vehicle, before the electricity consumption will affect the normal functions of the car.
    The cool box will stop automatically to ensure that the car’s battery does not run out.
  2. Method for adjusting the battery protection: Unlock the cool box by holding down the release button after which you press and hold SET for 3 seconds to show the current battery protection position of the refrigerator.
    By tapping the SET button, it is adjusted to the desired H-class, M-middle or L-layer. The factory setting is H Battery protection voltage
  3. parameter value and the remaining power is displayed on the screen.
Settings 12V voltage 24V voltage Remaining
battery display
L-low 9.6V 10.9V 21.3V 22.7V
M-middle 10.8V 11.4V 22.3V 23.7V
H-high 11.3V 12.5V 24.6V 26.0V

Tip: It is recommended to set the H-class when the cool box is connected to a vehicle, otherwise the car’s battery may be too empty and affect the normal ignition of the car; When connecting the cool box to an external or backup battery, it is recommended to set the M-mid range so that the cool box can work longer.
Tip: Due to the difference in the output voltage of different cars, such as the car refrigerator, the input voltage is too low for normal cooling (the error code on the screen shows F1), the battery protection equipment can be reduced by one

The meaning of the error code on the screen and how to deal with it
