Short Product Description

Stop waiting hours for your DIY projects to charge. This 3A High Current Lithium Charging Module utilizes the advanced IP2312 chip to deliver rapid, efficient power via a modern Type-C interface. Designed for 3.7V/4.2V or 4.35V ternary lithium batteries, it achieves up to 95% conversion efficiency. Whether you are building a custom power bank or upgrading a portable gadget, this compact CC/CV mode charger provides the professional-grade performance your electronics demand.

Key Features

3A High Current Output: Charges high-capacity lithium batteries up to 3x faster than standard modules.
Advanced IP2312 Main Control: Ensures stable, intelligent power management with synchronous rectification.
Type-C Input Port: Offers universal compatibility and robust physical connection for modern DIY builds.
Adjustable Charging Current: Defaulted at 3A, but easily modifiable to 1A by replacing a single resistor.
Dual LED Indicators: Clear visual feedback with Red for charging and Blue for fully charged status.
Synchronous Switching: Minimizes energy loss and heat generation during high-speed charging.

Full Product Description

Faster Charging for High-Demand DIY Projects

Standard charging modules often bottleneck at 1A, leading to frustrating downtime. Our IP2312 3A Charging Board solves this by providing a high-current output that significantly reduces charging cycles. The integrated Type-C input ensures compatibility with modern chargers and cables, making it a future-proof choice for your electronic builds.

Precision CC/CV Charging Logic

To maximize battery lifespan, this module employs a sophisticated Constant Current (CC) and Constant Voltage (CV) charging algorithm:

Trickle Mode: Gently revives batteries under 3V with 100mA.
Fast Charge: Rapidly pumps power at 3A once above 3V.
Smart Cut-off: Automatically stops and re-checks voltage every 4 minutes as it nears full capacity to prevent overcharging.

Professional Thermal Management & Efficiency

Heat is the enemy of electronics. Thanks to the synchronous switching architecture, this module reaches 93%–95% efficiency, keeping the board cooler even during peak 3A output. The compact $31mm \times 14.8mm$ footprint allows for easy integration into tight enclosures without compromising on power.

Note: This module does not include battery protection. For a complete safety setup, we recommend pairing this with a dedicated BMS/Protection board available in our store.

FAQ Section

Q: Can I use this for LiFePO4 (3.2V) batteries?
A: No, this module is specifically tuned for 3.7V/4.2V or 4.35V ternary lithium batteries. Using it with LiFePO4 may damage the battery.

Q: Does it have over-discharge protection for the battery?
A: No. This is a dedicated charging module. You must use a battery with a built-in protection circuit or add an external protection board.

Q: How do I change the current to 1A?
A: The default is 3A. To change to 1A, you need to remove the "2A" resistor on the board and solder a 135k resistor in its place.
