상품 특징

• 1. The ammeter used for testing must be connected in series with the 5V input terminal of the charging board.
• 2. Optimal charging current is 0.37C of the battery capacity (0.37 times the capacity). For example, a 1000mAh battery requires only 400mA. Excessive current accelerates charging but reduces efficiency, causing significant voltage drop after charging.
• 3. Avoid using overly thin or long charging cables, as they increase connection resistance. Thin cables lead to greater voltage drop after charging.
• 4. Ensure secure and good contact with the battery terminals. Poor contact will cause significant voltage drop after charging.
• 5. If the 5V input voltage is high (e.g., 5.2V or even 5.5V), the charging current may drop below 1000mA. This is normal. Higher voltage causes the chip to heat up, automatically reducing the charging current to prevent chip burnout. The chip operating at around 60°C is normal due to the high charging current.
• 6. Reverse polarity on the input does not affect the chip. However, reverse polarity on the output (battery side) will burn out the chip. Buyers should take note.
• 7.Module Features and Parameters: Interface: MINI Charging Method: Linear Charging Charging Current: 1A Accuracy: 1.5% Input Voltage: 4.5V-5.5V Full Charge Voltage: 4.2V Do not reverse the board.
