10Pcs Type-C Lithium Battery Charging Module 5V Input 3A High Current, DC-DC Step Down Charger Board with CC CV Mode for 3.7V 4.2V Single Cell Lithium Battery
Product Information
About this item
- This charging module is designed for single鈥慶ell lithium batteries with a nominal voltage of 3.7V. It provides regulated charging output up to 4.2V or 4.35V, suitable for common lithium battery charging requirements in compact power systems.
- The module uses a Type‑C input interface and operates from a 5V DC power source. It can be powered by USB adapters or regulated DC supplies, allowing flexible integration into modern electronic designs.
- Supports charging current up to 3A under appropriate power supply and thermal conditions. The charging current can be configured to match different battery capacities, helping support efficient charging behavior within rated limits.
- Implements constant current and constant voltage charging control. This charging method supports stable charging behavior by regulating current during initial charging and voltage during the final charging stage.
- Compact PCB layout allows easy installation in battery packs and embedded devices. Integrated protection features help manage over鈥慶urrent, over-voltage, and thermal conditions during charging operation.
Product Description
