This 4-channel universal charger handles Ni-MH, Ni-Cd, Li-ion, and LiFePO4 cells simultaneously across four independent slots. Each battery is monitored individually by a microprocessor with precise Pulse Width Modulation (PWM) control, ensuring safe and efficient charging. A single Li-ion or LiFePO4 cell can be fast-charged at up to 2A.
The high-contrast LCD screen provides real-time readouts of charging current (A), capacity (mAh), voltage (V), and battery percentage for each slot. Built-in safety features include error alerts for faulty batteries, reverse polarity protection, and safeguards against short circuits, overcharging, and overheating.

Jargon buster
Plain-language definitions for the technical terms used above.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
- Type-C
- USB Type-C (USB-C) is a small, reversible USB connector used for charging, power, and data transfer on many modern devices. A Type-C port or plug indicates the cable and charger connection needed to power, charge, or communicate with a device.
- USB Type-C
- USB Type-C is a small, reversible USB connector used for power, data and sometimes video on many modern devices. The connector itself does not guarantee a particular speed or voltage, so check the supported USB version, data rate and whether it carries more than 5V via USB Power Delivery.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
