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 that the connection is a few series of lithium batteries, we need to connect the corresponding pads on the tin. For example, the measured 2S battery (i.e., two 3.7V lithium batteries in series connection), it is necessary to short-circuit the corresponding pads on the S2 of the board.
S1-S8 modules can only choose one type of wiring, not allowed to have 2 or more short connections at the same time.

Pay attention to the selection of the corresponding number of battery strings, to be used in the corresponding voltage range. Do not exceed the maximum voltage of 4.3*N. (For example, choose the pad of S3 on the tin, then the module detection of the maximum do not exceed 4.3 * 3 = 12.9V)
1.When battery voltage is over N*3.3V,it will illuminate 1 block electricity quantity.
(note :N represents battery quantity)
2.When battery voltage is over N*3.5V,it will illuminate 2 blocks electricity quantity.
3.When battery voltage is over N*3.7V,it will illuminate 3 blocks electricity quantity.
4.When battery voltage is over N*3.9V,it will illuminate 4 blocks electricity quantity.
5.When battery voltage is less than N*3.3V, 4 blocks display will be off; it represents battery is less than 3.3V, and you can charge the battery.

1. Battery type electricity quantity display, Wide application fields: lithium battery
2. Working voltage: 3-34V, working current: 5mA, working temperature: -20-50?
3. Digital Color: outline red, display block blue/green (when battery electricity quantity is full, it will be all on)
4. Note: This model is not waterproof, the electronic components should be used in a dry environment.
