Description

The DFRobot Lithium Battery Charger V1.0 implements a constant-current/constant-voltage (CC/CV) charging algorithm tailored for 3.7V lithium-based cells. It ensures safe charging by terminating the cycle at a precise 4.2V with a C/10 cutoff, preventing overcharge and extending battery lifespan. The module includes a status LED for visual charge indication.

Designed for integration, its compact footprint and mounting holes allow it to be permanently installed within portable devices, drones, or robotic platforms. The USB Type-C interface provides universal power input compatibility, while the JST connector matches common battery pigtails, simplifying the wiring harness.

Key Features

  • Single-cell Li-Ion/LiPo charger with a high-accuracy 4.2V (±1.5%) termination voltage.
  • Selectable charging current via solder jumpers for 100mA, 500mA (default), 700mA, or 1000mA output.
  • Universal USB Type-C input port for convenient power sourcing from adapters or computer ports.
  • Standard 2-pin JST PH-series output connector for direct plug-in to compatible battery packs.
  • Compact and embeddable PCB design with two M2 mounting holes for secure mechanical installation.
  • Wide operating temperature range (-40°C to +85°C) suitable for industrial and outdoor applications.
  • Integrated charging status LED provides clear visual feedback for charge-in-progress and completion.
  • Reliable CC/CV charging profile with automatic C/10 cutoff for safe, maintenance-free operation.

Applications

  • Portable electronics and handheld IoT sensor nodes requiring integrated battery management.
  • Mobile robotics and drone platforms for on-board LiPo battery charging and maintenance.
  • Wearable technology and health monitoring devices with embedded rechargeable batteries.
  • Backup power systems and UPS modules utilizing single-cell lithium battery packs.
  • Educational and prototyping projects for learning about battery charging circuits and power management.

Frequently Asked Questions

What types of batteries is this charger module compatible with?

This module is specifically designed for charging single-cell (1S) 3.7V Lithium-Ion (Li-Ion) or Lithium-Polymer (LiPo) batteries. It is pre-set to a 4.2V termination voltage and uses a CC/CV charging algorithm. Do not use it with multi-cell packs, LiFePO4, NiMH, or lead-acid batteries.

How do I change the charging current from the default 500mA?

The charging current is configurable via solder jumpers on the PCB. You can select between 100mA, 500mA (factory default), 700mA, or 1000mA. Refer to the board's silkscreen or product documentation for the specific Jumper configuration. Use a current appropriate for your battery's capacity (e.g., 0.5C to 1C rate).

What input power source does this charger require?

The module is powered via its USB Type-C port. You can use any standard USB power source, such as a 5V wall adapter, computer USB port, or power bank. Ensure the source can supply the required current for your selected charge rate (e.g., a 5V/2A adapter for 1000mA charging).

How do I connect my battery to the charger module?

Connect your battery using a standard 2-pin JST PH-series connector (common on many small LiPo packs). Ensure correct polarity alignment. The module also provides terminal access points for direct soldering if a connector is not present. Always double-check polarity before applying power.
