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

 

Features:
1.Battery type electricity quantity display
2.Wide application fields:lithium battery
3.Using Method:connect display board positive and negative port with tested battery positive
and negative port,digital tube will display real-time battery electricity quantity
4.Digital Color:outline red,display block blue (when battery electricity quantity is full,
it will be all on)

 

Warm sound reminder: This model is not waterproof, if you use it outdoors, please make it waterproof, because the electronic components need to be used in a dry environment.
Lithium battery, lead-acid, nickel-metal hydride battery can be used to display the battery, as long as the required voltage is within the range of the parameter table.
How to use: Connect the positive and negative terminals of the display board to the two terminals of the battery under test, and the digital tube will display the real-time battery power

1. Battery-type power display, select the corresponding solder on the pad to detect the battery pack voltage corresponding to 1S-8S, which is very convenient.

3. How to use: Connect the positive and negative ports of the display board to the positive and negative ports of the battery under test, and the digital display tube will display the real-time battery power. Note that if you are connecting several series of lithium batteries, you must connect tin to the corresponding pads. For example, if you are measuring a 2S battery (that is, two 3.7V lithium batteries in series), you need to short-circuit the solder on the pad corresponding to S2 of the board.

4. Pay attention to selecting the corresponding number of battery strings, and use them within the corresponding voltage range. The maximum voltage should not exceed 4.3*N. (For example, if you choose S3 on the solder pad, the maximum voltage detected by the module should not exceed 4.3*3=12.9V)

The battery voltage is greater than N×3.3V, and the power is on for 1 grid (Note: N is the number of battery cells)

Display battery quantity parameters: (Note: N means battery quantity)
1. When the battery voltage exceeds N * 3.3V, 1 block of electricity will be illuminated
2. When the battery voltage exceeds N * 3.5V, 2 pieces of power will be illuminated
3. When the battery voltage exceeds N * 3.7V, 3 pieces of power will be illuminated
4. When the battery voltage exceeds N * 3.9V, 4 pieces of power will be illuminated
5. When the battery voltage is less than N * 3.3V, the 4 displays will turn off, indicating that the battery power is less than 3.3V and needs to be charged.
