Pin Configuration

Witty Fox 3.7V 5000mAh Li-Ion Battery Pinout Explanation
The Witty Fox 3.7V 5000mAh Li-Ion Battery is a rechargeable battery designed for use in various IoT projects and devices. It features a compact design with four pins, each serving a specific purpose. Here's a detailed explanation of each pin:
Pin 1: Positive Terminal (VCC)
--------------------------------
Function: Provides the positive voltage output from the battery.
Voltage: 3.7V
Current Capacity: Up to 2C rate (10A) for a short duration, 1C rate (5A) for a continuous discharge.
Connection: Connect to the positive terminal of your load, microcontroller, or circuit.
Pin 2: Negative Terminal (GND)
---------------------------------
Function: Provides the negative voltage output from the battery.
Voltage: 0V (Ground)
Connection: Connect to the negative terminal of your load, microcontroller, or circuit.
Pin 3: Thermal Protection (TP)
-------------------------------
Function: Provides a thermal protection feature to prevent the battery from overheating.
Operation: When the battery temperature exceeds 80C (176F), the TP pin will pull low (0V) to indicate an overheating condition. When the temperature drops below 80C, the TP pin will return to its high-impedance state.
Connection: Connect to a microcontroller or monitoring circuit to detect overheating conditions.
Pin 4: Battery Protection (BP)
-------------------------------
Function: Provides a battery protection feature to prevent overcharge, over-discharge, and short-circuit conditions.
Operation: The BP pin will pull low (0V) when the battery is fully charged or when an error condition occurs (e.g., overcharge, over-discharge, or short-circuit).
Connection: Connect to a microcontroller or charging circuit to detect protection events and control the charging process.
