1-4 strings of 3.7V lithium battery power indicator display module 4 strings of 3.7V lithium battery power detection module -88251

2、 Introduction to parameters

1. Power supply voltage: 1 series 4.2V; 2 strings of 8.4V; 3 strings of 12.6V; 4 strings 16.8V

2. Static power consumption: ≈ 0

3. Maximum working current: ≈ 6.3mA (when 4 series are fully charged)

4. Indicator light continuous illumination time: 2S-6S (the lower the input voltage, the shorter the duration)

5. Scope of application: 1-4 strings of 3.7V lithium batteries (for other strings/voltages in bulk, please consult if they can be customized)

① Short circuit 1.2.3 Jumper pad is a 3.7V lithium battery with 1 string of battery capacity display

② Short circuit 2 and 3 jumper pads for 2 strings of 3.7V lithium battery power display

③ Short circuited 3 jumper pads with 3 strings of 3.7V lithium battery power display

4 series 3.7V lithium battery power display for non short circuited jumper pads

4、 Usage and precautions

When using the module, strictly follow the positive and negative poles marked on the module and connect them to the battery. Do not reverse the positive and negative poles, as it may burn out the module;

Due to differences in components, there may be an error of within 0.03V in the battery voltage corresponding to the actual indicator lights of individual modules:

When measuring a string of 3.7V lithium batteries, the indicator light goes out and follows a slight flashing, which is a normal phenomenon (on

Very low degree):

You can switch the measurement string number of the module by changing the jumper pad welding method on your own:

The module can only measure the total voltage of the battery, and cannot measure the voltage of each battery
