Witty Fox 3.7V 10000mAh Li-Ion Battery Pinout Documentation
The Witty Fox 3.7V 10000mAh Li-Ion Battery is a compact and high-capacity power source designed for various IoT and electronics applications. This documentation provides a detailed explanation of the battery's pinout and how to connect them correctly.
Pinout Structure:
The Witty Fox battery has 4 pins, each with a specific function. The pinout structure is as follows:
Pin 1: Positive Terminal (VCC)
Function: Provides the positive voltage output of the battery (3.7V)
Connection: Connect to the positive terminal of your device or circuit
Caution: Ensure proper polarity to avoid damage to the battery or connected devices
Pin 2: Negative Terminal (GND)
Function: Provides the negative voltage output of the battery (0V)
Connection: Connect to the negative terminal of your device or circuit
Caution: Ensure proper polarity to avoid damage to the battery or connected devices
Pin 3: Battery Protection Circuit (BPC) Input
Function: Connects to the Battery Protection Circuit (BPC) module to monitor and control the battery's state of charge
Connection: Typically connects to the BPC module's input pin
Note: The BPC module is responsible for preventing overcharge, over-discharge, and short-circuit protection
Pin 4: Temperature Sensor (NTC) Output
Function: Provides an analog output signal indicating the battery's internal temperature
Connection: Connect to an Analog-to-Digital Converter (ADC) or a dedicated temperature monitoring circuit
Note: The NTC (Negative Temperature Coefficient) thermistor output can be used to monitor the battery's temperature and prevent overheating or overcooling
Connection Guidelines:
1. Polarity Matters: Ensure correct polarity when connecting the battery to your device or circuit. Reverse polarity can damage the battery, connected devices, or both.
2. Use Appropriate Connectors: Use suitable connectors, such as JST or Molex, to connect the battery to your device or circuit.
3. Protect the Battery: Implement proper battery protection mechanisms, such as overcharge and over-discharge protection, to prolong the battery's lifespan.
4. Monitor Temperature: Use the temperature sensor output to monitor the battery's internal temperature and prevent overheating or overcooling.
5. Follow Safety Precautions: Handle the battery with care, avoiding short-circuits, punctures, or crushing, which can cause damage or fires.
By following these guidelines and understanding the pinout structure, you can safely and effectively integrate the Witty Fox 3.7V 10000mAh Li-Ion Battery into your IoT or electronics project.
