1-8S 1S/2S/3S/4S Single 3.7V Lithium Battery Capacity Indicator 4.2V Display Electric Vehicle Battery Power Li-ion

The power display panel can be used by lithium lead acid nickel battery as as the demand voltage is within the range of the table.

Working voltage: 3-34v
Working current 5mA
Operating temperature: - 20~50 ℃
Voltage error 2%
1. Warm sound prompt: this model is not waterproof. If it is used outdoors, please do a good job of waterproof, because electronic components need to be used in a dry environment.
2. Usage: Connect the positive and negative terminals of the display board to the positive and negative terminals 2 of the d battery, and the nixie tube will display the real-time battery power
3. Battery type power display. Select tin on the corresponding bonding pad to detect the battery pavoltage corresponding to 1S-8s, which is very convenient.

Only one S1- optional pad can be connected, and two or more short circuits are not allowed at the same time

3. Usage : Connect the positive and negative portsof the display panel to the positive and negative
ports of the battery under test. The dialdisplay tube will display the real-time batterypower. Note that after connecting a few series oflithium batteries in series, it is necessary toconnect tin to the corresponding pads.For connect tin to the corresponding pads. Forexample，if a 2s battery is measured ie, two 3.7Vlithium batteries are connected in series, a
short circuit on the pad corresponding to S2 ofthe board is required.

4. Pay attention to the number of correspondingbattery strings and usethem within thecorresponding voltage range. Do not exceed avoltage of 4.3*N at most. For example, if the tinon the pad of s3 is selected,the maximum voltagedetected by the module should not exceed4.3*3=12.9V
The battery voltage is greater than N x 3.3V,and the battery voltage is 1 grid.Note: N isthe number of battery segments

Display the quantity of electricity :Note: N indicates the number of batteries1. When the battery voltage exceeds N * 3.3V, itwill illuminate 1 block
2. When the battery voltage exceeds N* 3.5V，itwill illuminate 2 pieces of electricity
3. When the battery voltage exceeds N* 3.7V,itwill illuminate 3 blocks
4. When the battery voltage exceeds N * 3.9V,itwill illuminate 4 blocks
5. When the battery voltage is less than N* 3.3V,the four display screens will be turned off,indicating that the battery power is less than3.3V and needs to be charged.
