It charges up to a 4.2V cut-off voltage, which is the standard full-charge threshold for most 18650 Li-ion cells. Always verify your battery's specifications before use.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this charging board include battery over-discharge or short-circuit protection?\u003c\/h4\u003e\n\u003cp\u003eA: No. This module does not include battery protection circuitry (no over-discharge, over-voltage, or short-circuit protection). If your project requires protection features, you will need to add a separate battery protection board (BMS) in your circuit design.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I adjust the charging current on this module?\u003c\/h4\u003e\n\u003cp\u003eA: The board ships set to a default 3A charging current. To reduce the current to 2A, simply remove the onboard resistor. For 1A charging, replace the resistor with a 135kΩ resistor. This makes it easy to fine-tune the charge rate to suit your battery capacity and application requirements.\u003c\/p\u003e\n\u003ch4\u003eQ: What does the USB Type-C input requirement mean for this module?\u003c\/h4\u003e\n\u003cp\u003eA: The board accepts 4.5–5.5V input via its Type-C USB port, meaning a standard 5V USB-C power adapter or power bank will work as the input source. The module then regulates this to efficiently charge your 18650 Li-ion battery at the selected current.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this 18650 battery charging board compatible with all 3.7V lithium-ion batteries?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes — the IP2312 charging module is designed specifically for 3.7V lithium-ion (Li-ion) cells, including standard 18650 batteries.
