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.
