Battery protection function: test the operating status of the lithium battery. Protect the battery from overcharging or overcharging, provide battery protection for your RC device.
Voltage visualisation: simply connect the balance plug and the LED passes through the individual cell voltages and lists the total voltage. (Comes with a black protective case)
Adjustable voltage: when the voltage is below the set value, a buzzer sounds with red LED, preset value 3.3 V. Press the button to change and save the voltage setting
Convenient and fast: works with any 1-8S Lipo / Li-Ion / LiMn / Li-Fe RC drone battery. Protect the battery from overcharging and over-discharging. Simply plug it into the balance plug and the LED will go through the individual cell voltages and list the total voltage
Exquisite and practical: super loud alarm sound makes it easier to find your drone (with a special frequency, the alarm sound can be heard even in noisy environments with a maximum alarm sound of up to 100 decibels)
