Digital LCD Battery Meter for Lithium Cells (18650, 18350, 26650): 2.8-30V Voltage Range, 0-10A Current Measurement, Electric Voltmeter & Multimeter

Note: 

The discharge resistance is not included in the packing list. 

Battery voltage:

Measurement range: 2.8 ~ 26.0V.

Resolution: 0.1V.

Accuracy: 2%.

Battery level:

Battery level is shown through the battery level grid on the

LCD screen and it has a total of five levels. Battery level is

distinguished by the battery voltage.

At full level it displays 5 grids, at 4/5 level it displays 4 grids,at 3/5 level it displays 3 grids, at 2/5 level it displays 2 grids,at 1/5 level it displays 1 grid,when comes the battery cut-off voltage it will display format 0 (only display battery frame).

The voltage which is measured when power on is set to full battery level,and the battery cut-off voltage is set to zero level.

The battery cut-off voltage can be set, the range is 2.8 ~ 26.0V, but not more than the full-scale voltage.

The full-scale voltage of the battery can be set, the range is 2.8V ~ 30.0V, but not less than the cut-off voltage.

Load current:

Measurement range:0.1--10.0A

Resolution:0.1A

Measurement accruacy:2%

Load Resistance:

Measurement range:0--999Ω,display “oL”when it is greater than 999Ω

Resolution: When the resistance is less than 10Ω, the resolution is 0.01Ω, when the resistance is greater or equal 10Ω but less than 100Ω,the resolution is 0.1Ω, when the resistance is greater or equal 100Ω but less than 1000Ω, the resolution is 1Ω.

Measurement accruacy:2%

Backlight control:

The backlight defaults to turn off state when power on, and you can control the backlight trun on or off by the key

Opterating instruction:

Cut-off voltage of the battery and full-scale voltage settings

Step 1:Long press the button for 3 seconds to enter the battery cut-off voltage and full-scale voltage setting state;

Step 2: After entering the state, voltage  area  displays the current battery cut-off voltage flickeringly, and use the zero battery level symbol to indicate it is the cut-off voltage setting state (as shown in Figure 3.1); then you can shot press the button to do the adding one adjustment,and long press the button to do a quick adding one adjustment;

Step 3: When there is no button operation more than three seconds, it automatically enter into the full-scale voltage setting state;

 Step 4: After entering this state, voltage area displays the current full battery level voltage flickeringly, and use the full battery level symbol to indicate it is the full-scale voltage settings state(as shown in Figure 3.2); setting method is as same as the cut-off voltage;

Step 5: When there is no button opteration more than three seconds, it will automatically save, if there is no error after saving then it will quit automatically, if the value is incorrect or save incorrectly will display Err SAu 1 second, and exit.

Note:

Lithium battery is powered through LDO, the power supply voltage should greater than 2.8V.
