1pcs Lithium Battery Capacity Indicator Module,Blue

Origin:CN(Origin)Type:Voltage RegulatorOperating Temperature:-20℃~+50℃Working voltage: 3-34Vworking current:5mAThe voltage error:2%Size: 43.5×20cmHow to use: 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.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.For example, if a 2S battery is measured (ie, two 3.7V lithium batteries are connected in series), a short circuit on the pad corresponding to s2 of the board is required.The battery voltage is greater than N × 3.3V, and the battery voltage is 1 gridDisplay the quantity of electricity parameter: (Note: N indicates the number of batteries)When the battery voltage exceeds N * 3.3V, it willilluminate 1 blockWhen the battery voltage exceeds N * 3.5V, it willilluminate 2 pieces of electricityWhen the battery voltage exceeds N * 3.7V, it willilluminate 3 blocksWhen the battery voltage exceeds N * 3.9V, it willilluminate 4 blocksWhen the battery voltage is less than N * 3.3V, the four display screens will be turned off, indicating that the battery power is less than 3.3V and needs to be charged.

• Lithium-ion battery The battery indicator board that can be used in Ni-MH batteries, as long as the required voltage is within the range of the parameter list.
• Note that after connecting a few series of lithium batteries in series, it is necessary to connect tin to the corresponding pads
• Pay attention to 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 tin on the pad of S3 is selected, the maximum voltage detected by the module should not exceed 4.3×3=12.9V)
• Warm sound tips: This model is not waterproof. If it is used outdoors, please waterproof it, because the electronic components should be used in a dry environment.
