Battery Capacity Indicator(1S/8S-3.7V)

Description

1S–8S Lithium Battery Capacity Indicator The 1S–8S Battery Capacity Indicator provides a simple way to monitor the remaining power of lithium battery packs. It supports battery configurations from 1S to 8S and operates within a voltage range of 3V to 34V. The bright digital display shows the battery level in real time. This makes the module suitable for portable electronics, DIY projects, robotics, and custom battery-powered devices. Key Features Supports 1S to 8S lithium battery packs Wide operating voltage from 3V to 34V Displays the remaining battery capacity in real time Low operating current of approximately 5mA Compact and easy to install Suitable for DIY electronics and portable devices Configurable through solder pads 1S selection pad comes pre-soldered Technical Specifications Supported Battery Configurations: 1S–8S Nominal Cell Voltage: 3.7V Operating Voltage: 3V–34V DC Operating Current: Approximately 5mA Voltage Accuracy: ±2% Operating Temperature: -20°C to 50°C Module Size: 43.5 × 20 mm Water Resistance: Not waterproof How to Select the Battery Type Select the required battery configuration by soldering the corresponding pad on the board. The module supports configurations from 1S to 8S. The 1S pad comes pre-soldered . Remove or change the solder connection when using another battery configuration. How to Connect Connect the positive terminal of the module to the battery’s positive terminal. Then, connect the negative terminal to the battery’s negative terminal. After connection, the display will show the battery’s remaining capacity in real time. Applications This battery indicator is suitable for: Lithium battery packs Portable electronic devices Robotics projects DIY power supplies Rechargeable battery systems Educational and STEM projects Custom electronic circuits Important Notes Select the correct battery configuration before connecting the module. Do not exceed the supported voltage range. This module is not waterproof. Keep it away from water, moisture, and wet environments. A ±2% voltage tolerance may occur, so the module is not suitable for precision measurement.
