Important Notes

• Ampere meter should only be connected to the 5V input end of the module.
• It's recommended that the charging current be 37% of the battery capacity. For example, 400mA is sufficient for a 1000mAh battery.
• Avoid using excessively long connection wires for optimal performance.
• Ensure that the connection points are secure and stable.
• If the input voltage exceeds 5.2V, the charging current may reduce to less than 1000mA as a safety measure to protect the chip from damage.
• While input reversal will not affect the chip, reversing the output (battery terminals) may cause damage to the chip.

Applications

This module is designed for charging single or multi-section parallel lithium rechargeable batteries from a USB power source.
