Ni-Cd Ni-MH Battery Charger Module 1.2–24V PCB Board

Universal Ni-Cd & Ni-MH Battery Charging Board Module

This compact PCB charging board is built for hobbyists, makers, and electronics enthusiasts who need a reliable, adjustable constant-current solution for charging nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH) rechargeable batteries. Covering a wide voltage range of 1.2V to 24V, it handles everything from single-cell AA/AAA packs to multi-cell battery strings — all from a single, easy-to-use board.

Key Features

• Wide Battery Compatibility: Charges Ni-Cd and Ni-MH batteries across a broad voltage range (1.2V – 24V), supporting 1.2V, 2.4V, 3.6V, 12V, and more.
• 4 Selectable Output Currents: Choose from 50mA, 100mA, 200mA, or 300mA via short-circuit cap conversion — match the current to your battery's capacity for safe, efficient charging.
• Wide Input Voltage: Accepts DC 6–32V input, making it compatible with a variety of power supplies and adapters (not included).
• Constant Current Charging: Delivers stable, consistent current for reliable battery conditioning cycle after cycle.
• Compact Form Factor: Measures approximately 51 × 38mm — small enough to integrate into DIY enclosures or custom electronics projects.
• Durable & Reusable: Quality PCB construction ensures long service life and repeated use.
• Easy to Use: Simple jumper/cap-based current selection requires no complex configuration.

Frequently Asked Questions

Q: What types of batteries does this charger module support?

A: This charging board is designed specifically for Ni-Cd (nickel-cadmium) and Ni-MH (nickel-metal hydride) rechargeable batteries. It supports battery pack voltages ranging from 1.2V up to 24V, covering a wide range of cell configurations.

Q: How do I select the charging current?

A: The board features a short-circuit cap (jumper) system that lets you select from four output current levels: 50mA, 100mA, 200mA, or 300mA. Choose the current based on your battery's capacity — a common guideline is to charge at roughly 1/5 to 1/10 of the battery's mAh rating.

Q: Does this module automatically stop when the battery is fully charged?

A: No — this module uses constant-current charging without an automatic cutoff. You will need to track charging time manually. For example, a 1000mAh battery charged at 200mA will take approximately 6 hours to reach full charge.

Q: What power supply do I need to use with this board?

A: The input voltage must be between DC 6V and 32V, and it must be at least 5V higher than the voltage of the battery pack you are charging. The power adapter is not included and must be sourced separately.
