4PCS 2S 2 Series Lithium Battery Level Indicator Capacity Module Ni-MH 8.4V 4 Sections Blue LED Display Electric Vehicle Battery Power Tester Li-po Li-ion
Battery pack display electricity quantity parameter: 1.When battery voltage is
over N3.3V,it will illuminate 1 block electricity quantity (note:N represents
battery quantity) 2.When battery voltage is over N3.5V,it will illuminate 2
blocks electricity quantity 3.When battery voltage is over N3.7V,it will
illuminate 3 blocks electricity quantity 4.When battery voltage is over
N3.9V,it will illuminate 4 blocks electricity quantity 5.When battery voltage
is less than N3.3V,4 blocks display will be off;it represents battery is less
than 3.3V,and you can charge the battery Battery description: 4V lead acid

Product Features
  

         
The 2S battery capacity indicator module can be used to display lithium battery, lead acid battery, and Ni-MH battery.
         
Clear and bright display, outline red, display block Blue. The different electricity quantity will illuminate corresponding blocks electricity quantity.
         
How to use it: Connect the positive and negative terminals of the display board to the positive and negative terminals of the battery under test. The digital tube displays the real-time battery power.Note : after connecting a few series of lithium batteries in series, it is necessary to connect t-i-n to the corresponding pads.For example if a 2S battery is measured (two 3.7V lithium batteries are connected in series), a short circuit on the pad corresponding to S2 of the board is required.
         
Widely applications: Can be widely applied to portable mobile equipment, electro mobile, balance car, cleaning machine, measuring equipment etc. battery capacity indicator.
         
Note: The electricity quantity parameter is a reference value, there will be about 2% error range; This model is not waterproof, the electronic components should be used in a dry environment; The number of corresponding battery strings and use them within the corresponding voltage range. Do not exceed a voltage of 4.3*N at most.(for example, if the t-i-n on the pad of S3 is selected, the maximum voltage detected by the module should not exceed 4.3*3=12.9 V).
