5V 2.4A Lithium Battery Fast Charging Discharging Module

5V 2.4A Lithium Battery Fast Charging Discharging Module is an integrated single-cell (1S 3.7V/4.2V) lithium-ion power bank charge and boost discharge management board featuring both USB Type-C input and USB Type-A output ports. Built around an integrated synchronous switch-mode power bank SoC, this module charges 18650, 21700, or LiPo cells at up to 2.4A while stepping up the 3.7V battery voltage to a regulated 5.0V 2.4A USB output. Four onboard LED fuel-gauge indicators display real-time battery capacity in 25% increments.

Key Features:

• Bidirectional 2.4A Charge & Discharge: High-efficiency synchronous switching charger and 5V 2.4A step-up boost converter on one compact PCB.
• USB Type-C Input & USB-A Output: Accepts 5V charging input via USB Type-C and delivers 5V output through a standard USB Type-A female port.
• 4-LED Battery Capacity Display: Integrated 4-stage LED fuel gauge indicates 25%, 50%, 75%, and 100% state-of-charge during charging and discharging.
• Comprehensive Lithium Protection: Includes overcharge (4.2V), over-discharge (3.0V), output overcurrent, short-circuit, and thermal overload protection.
• Auto Load Detection & Sleep: Automatically wakes up when a mobile device is plugged in and enters micro-amp standby when idle.

Technical Specifications:

• Input Voltage (USB Type-C): 4.75V to 5.25V DC
• Maximum Charging Current: Up to 2.4 A
• Target Battery Chemistry: 1S 3.7V Li-ion / LiPo (4.20V ±1% Full Charge Cut-off)
• Boost Output Voltage (USB-A): 5.0V ± 0.15V DC
• Maximum Discharge Output Current: 2.4 A
• Conversion Efficiency: Up to 92%
• Standby Quiescent Current: < 50 μA

Mechanical Specifications:

• Connectors: 1 × USB Type-C Female Input, 1 × USB Type-A Female Output, B+/B- solder tabs
• Onboard Button: Tactile pushbutton for manual LED battery level check and output activation
• PCB Material: FR-4 Double-Sided Fiberglass Board with shielded power inductor
• Weight: Approximately 6 grams

Dimensions:

• Length: 28.0 mm
• Width: 18.0 mm
• Height: 7.5 mm

Pinout and Wiring:

• B+ Pad: Connect to 3.7V Lithium Battery Positive (+) terminal using short, heavy-gauge wire (18–20 AWG).
• B- Pad: Connect to 3.7V Lithium Battery Negative (-) terminal.
• USB Type-C Port: 5V DC charging input from wall adapter.
• USB Type-A Port: 5V 2.4A regulated DC output to smartphones, tablets, or 5V USB loads.
• Note: Parallel multiple 18650 cells (B+ to B+, B- to B-) to increase total capacity; never connect cells in series (2S/3S will destroy the IC).
