★ This module is designed for single-cell lithium battery or multi-cell lithium battery charging. The charging port can draw power from a USB port.
★ The ammeter for testing current must be connected
only to the 5V input terminal of the charging board.
★ The charging current should preferably be
0.37C of the battery capacity (i.e., 0.37 times the capacity). For example, a 1000mAh battery only requires a 400mA charging current. Excessively fast charging yields poor results and causes greater voltage drop after full charging.
★ The charging connection wire should
not be too thin or too long. This results in large resistance. A too-thin wire leads to significant voltage drop after full charging.
★ Ensure good contact with the battery terminals. Poor contact also causes voltage drop after full charging.
★ If the 5V input voltage is slightly high (e.g., 5.2V to 5.5V) and the charging current is less than 1000mA, this is normal. The chip automatically reduces the charging current to prevent burnout. A chip temperature of around 60°C during operation is normal since the charging current is large.
★
Reverse polarity input does not damage the chip, but reverse connection of the output (battery side) will burn the chip. Please pay attention!

☆ Product Features ☆
★ This module uses the highly mature
TP4056 charging chip, which features a simple peripheral circuit structure, excellent protection performance, and high charging accuracy.
★ The module is manufactured via fully automated mechanical processing with
SMD (Surface Mount Device) components. Each board undergoes pre-shipment testing, ensuring high reliability.
★ The charging current can be
easily adjusted by modifying the fixed resistor on the circuit board to change the output range from 100mA to 1000mA, making it highly convenient.
