1-3S Lipo Battery Voltage Display
[1-1S checker]

Specially designed for checking the unit cell voltage of Lithium polymer batteries.

Directly plug the voltage checker into the balance charging plug of the battery pack, it will display the voltage of each cell in turn from cell 1 to cell 3, and then repeat.

 Firstly it will show the voltage of first cell, there are 3 points on the LED screen which is used to indicate which cell it is measuring, when the point on right side light up, it indicates the first cell, and then will show the second cell voltage, and the middle point will light up, and then the third cell voltage, in the mean time, the left point will light up, if there is no second of third cell, it will display 'NO'.

Weight: 8 grams  0.29 oz

Operating Voltage 0V to 4.3V (input voltage higher than 4.3V or wrong polarity may result in damage to the tester)

The lowest pin is 'negative' when facing the LED display.

The round point on the LED is not digital point, it is used for indicating the current cell, the right one denotes cell no. 1, the middle point denotes cell no. 2, the left point denotes cell 3. So when you see the LED shows 38.7, it does not mean the voltage is 38.7V, but 3.87V for cell No. 2.
