SOLDERED DEBO SEN 1S BAT - Developer boards - Battery indicator for 4.2 V batteries
15.43 EUR
A battery indicator is a special accessory for lithium batteries that measures the condition of the battery very precisely. This accessory is compatible with Arduino (or a compatible board such as Dasduino) and provides precise monitoring via the I2C interface. The main functions include measuring the current voltage in millivolts, the state of charge in percent and the remaining capacity in milliampere-hours. It is suitable for 1S batteries.- Current voltage value is displayed in mV
- State of charge is displayed in %
- Remaining capacity is measured in mAh
- communicates via the I2C interface
- contains connections for JST and quick connect terminal
This accessory offers additional connection options that facilitate integration into existing projects. It has easyC connections that simplify I2C communication with microcontrollers. There is also a JST input for any pouch battery from the manufacturer's range and a quick connect terminal for sources without a JST connection. This flexible connectivity makes the battery indicator a versatile addition for many applications where accurate monitoring of battery performance is critical.
Technical specifications
- Batteries: 1S (4.2 V)
- Communication: I2C
- Measurements: voltage, state of charge, capacity
- easyC/Qwiic compatibility
- Dimensions: 38 x 22 mm
In summary, the battery indicator is an indispensable tool for developers and technicians who need to monitor the exact condition of lithium batteries. Its precision and versatility in connectivity make it a valuable component in any battery management system.
easyC
easyC is a robust connection system that optimizes the connection using JST-SH compatible connectors (JST 4-pin) of microcontrollers, sensors and actuators. It offers solderless connections, serial connections of multiple devices (daisy-chaining), error-free design, parallel connection, universal compatibility and intermediate compatibility with Qwiic (Sparkfun connection system), simplifying prototype development. Further information on easyC can be found under ''Data sheets''.
