RUNCCI-YUN 4PCS 1S 1 Series Lithium Battery Capacity Indicator Module Ni-MH 3.7V 4 Sections Blue LED Display Electric Vehicle Battery Power Tester Li-po Li-ion

• ✔The 1S battery capacity indicator module is used to display lithium, lead-acid, and Ni-MH batteries.
• ✔Clear and bright display, red outline, blue indicator block. The corresponding block lights up when the current levels are different.
• ✔Application: Connect the positive and negative terminals of the indicator board to the positive and negative terminals of the battery to be tested. The digital display shows the battery power in real time. Note: After connecting multiple lithium batteries in series, the t-i-n must be connected to the corresponding pads. For example, when measuring a 2S battery (two batteries connected in series), a short circuit is required at pad S2 on the board.
• ✔Wide range of applications: Widely used for battery capacity indicators in portable mobile devices, electric vehicles, weighing vehicles, cleaning machines, measuring devices, etc.
• ✔Note: The "current level" parameter is a reference value with an error tolerance of approximately 2%. This model is not waterproof. The electronic components should be used in a dry environment. Use the appropriate number of battery strings and use them within the appropriate voltage range. Do not exceed a maximum voltage of 4.3*N. (For example, if t-i-n is selected on the S3 pad, the maximum voltage detected by the module should not exceed 4.3*3 = 12.9V.)

Battery indicator parameters: 1. When the battery voltage is above N*3.3V, one block lights up (Note: N stands for battery capacity). 2. When the battery voltage is above N*3.5V, two blocks light up. 3. When the battery voltage is above N*3.7V, three blocks light up. 4. When the battery voltage is above N*3.9V, four blocks light up. 5. When the battery voltage is below N*3.3V, the four-block indicator goes out. This means the battery voltage is below 3.3 V and the battery can be charged. Battery Description: 4 V Lead-Acid Voltage Range: Battery voltage > 3.3 V, 1 grid lit.
