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

The power display panel can be used by lithium lead acid nickel hydrogen battery as long as the demand voltage is within the range of the parameter 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 tested 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 pack voltage corresponding to 1S-8s, which is very convenient.

Only one S1-S8 optional pad can be connected, and two or more short circuits are not allowed at the same time

1、 Application areas: 1S to 8S lithium battery, the corresponding voltage battery can be(specifically as a table)
3. Usage : Connect the positive and negative ports of the display panel to the positive and negative
ports of the battery under test. The digital display tube will display the real-time battery power. Note that after connecting a few series of lithium batteries in series, it is necessary to connect tin to the corresponding pads. For connect tin to the corresponding pads. For example if a 2s battery is measured (ie, two 3.7Vlithium batteries are connected in series), a
short circuit on the pad corresponding to S2 of the board is required.
4. Pay attention to the number of corresponding battery strings and use them within the corresponding voltage range. Do not exceed voltage of 4.3*N at most. (For example, if the tenon the pad of s3 is selected, the maximum voltage detected 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 is the number of battery segments)

Display the quantity of electricity parameter:(Note: N indicates the number of batteries)1. When the battery voltage exceeds N * 3.3V, it will 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.
