This compact TC4056A/TP4056 linear charging module safely charges 3.7V lithium batteries via a Micro USB input or solder joints. It includes an integrated battery management system (BMS) chip to protect cells against over-discharge and overcurrent conditions.
High-Performance Lithium Battery Charger Module with Dual Protection
Overview
This versatile charging board is designed for charging single-cell lithium-ion or lithium-polymer (Li-Po) batteries, such as the popular 18650 cells. Powered by the reliable TC4056A/TP4056 linear charging controller, it manages the entire constant-current/constant-voltage (CC/CV) charging cycle. The board comes equipped with an integrated battery management system (BMS) IC, providing essential safety safeguards that standard standalone chargers lack.
Dual Safety Protection
Standard lithium batteries are highly sensitive to electrical extremes. This module includes a dedicated protection circuit featuring over-discharge and overcurrent monitoring.
- Over-Discharge Protection: Automatically cuts off power when the battery drops to 2.5V, preventing permanent cell degradation.
- Overcurrent Protection: Instantly stops the circuit if the load demands more than 3A, protecting both your battery and your project from short circuits.
Convenient Power Inputs
The module offers exceptional hardware flexibility for makers and developers. It features a standard Micro USB receptacle, allowing you to power it directly from any common 5V phone charger, wall adapter, or computer USB port. For permanent installations or custom enclosures, it retains dedicated positive and negative input solder joints next to the USB port, letting you hardwire a steady 5V DC power source directly.
