Featuring a high-density integrated design, this module delivers efficient charge\/discharge performance of up to 2.4A and supports multiple safety mechanisms, including overcharge and over-discharge protection. Simply solder the battery to quickly build a prototype system, significantly shortening the R\u0026amp;D and validation cycle for smart hardware products.\u003c\/p\u003e\u003cp\u003eImportant Notes:\u003c\/p\u003e\u003cp\u003e1. The output includes short-circuit protection, but the battery interface lacks reverse connection protection; connecting the battery in reverse will cause damage.\u003c\/p\u003e\u003cp\u003e2. Due to the compact design, some heat dissipation capabilities have been sacrificed; noticeable heat generation occurs when the operating current exceeds 2A.\u003c\/p\u003e\u003cp\u003e3. Does not support charging Apple devices via a Type-C adapter; Apple users should exercise caution when purchasing.\u003c\/p\u003e\u003cp\u003e4. Charging current depends on battery capacity, discharge rate, current battery voltage, cable length and gauge, ambient temperature, and other factors.\u003c\/p\u003e\u003cp\u003e5. Automatic switching between buck and boost modes has a 1–2 second delay. After the battery is fully discharged, the module will maintain input power to charge the battery. It will only automatically switch input\/output modes after the charging state ends. When powering devices with reverse power supply capabilities, please disable this feature or exit charging mode promptly.\u003c\/p\u003e\u003cp\u003ePackage Contents:\u003c\/p\u003e\u003cp\u003eModule x1\u003c\/p\u003e\u003ch3\u003eOptions\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e A, B\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003ch4\u003eQ: What is the Mini DC 5V 2 4A Charge Discharge Module 3 7V 4 2V 18650?\u003c\/h4\u003e\u003cp\u003eA: The Mini DC 5V 2 4A Charge Discharge Module 3 7V 4 2V 18650 is a quality decor pick.
