Universal Fast Charge Lithium Battery Charger Module with Step - Up Booster - 15W 3A Power Supply (Micro12V Battery box)

🔌 Type-C 15W 3A 18650 Lithium Battery Charger Module is an advanced DC-DC step-up booster designed for fast charging and high-efficiency power supply applications. This versatile converter provides a reliable solution for powering low-power DC devices while ensuring seamless integration with battery systems.

💍 This innovative UPS-15W module is capable of effortlessly switching between an external power source and battery, ensuring uninterrupted operation without any delay. It is ideal for applications such as low-power devices and measuring instruments that require continuous power supply, even during power interruptions.

🔋 The robust module incorporates four essential functions: lithium battery charging, battery protection, boost output, and UPS switching. It features a convenient Micro USB charging interface and accepts direct DC 5V input for efficient battery charging. A dual-color LED indicator visually communicates the charging status, with a steady green light signaling that charging has completed while automatically halting further charge to preserve battery health. It also includes two high-quality holders for 18650 batteries, providing flexibility for a variety of setups.

🧩 Key Functions:

• UPS Function: When powered, the module supplies the load directly while charging the lithium battery. If the power supply fails, it automatically draws power from the battery to continue supplying the load seamlessly.
• Boost Circuit: Capable of supporting peak power up to 20W and rated power at 15W, the built-in boost circuit utilizes high-efficiency components, achieving up to 96% efficiency. The module supports optional output voltages of 5V, 9V, or 12V, suitable for various applications.
• Lithium Battery Protection: Comprehensive protection features include safeguards against over-charging, over-discharging, over-temperature, and over-current conditions. If the module encounters a fault state, it will automatically reset and resume output once connected to a power source.
• Compact Design: With dimensions of 89mm x 42mm x 22.4mm, the module provides a space-efficient solution, making it easy to integrate into existing systems.

🧩 Operational Instructions:

• For optimal UPS operation, ensure a battery is installed and that the 5V input power supply is adequate to maintain a continuous output, allowing the battery to engage instantly during outages.
• To reduce energy consumption, consider soldering down the output indicator after all necessary testing, which can decrease current usage significantly without impacting output performance.
• In case the module enters a protection state due to accidental triggering, it can be reset by connecting the charging port to a 5V power supply, restoring output functionality.
• A larger output capacitor in some 5V power supplies may lead to slow voltage drops upon power failure. In such cases, a 1K discharge resistor can be connected in parallel to the 5V input to facilitate quicker power transfer to the battery system.
• For increased power capacity, multiple 18650 cells can be connected in parallel while maintaining full functionality of the module.
