ToolkitRC LiPo Charger Q4AC – Smart 4-Channel Charger for Demanding RC and FPV Enthusiasts

The ToolkitRC LiPo Charger Q4AC is a powerful and intelligent 4-channel battery charger designed for FPV pilots, drone builders, and RC car, airplane, and boat enthusiasts. With four fully independent charging channels, the Q4AC allows you to charge up to four batteries simultaneously using different charging settings, saving time and making everyday battery maintenance significantly more efficient. Whether you’re working in your workshop or preparing for a race or flying session, the Q4AC delivers professional performance in a compact package.

In addition to its impressive charging capabilities, the ToolkitRC LiPo Charger Q4AC features a bright 3.5-inch IPS display with a 480 × 320-pixel resolution, providing a clear and detailed overview of all charging parameters. The intuitive user interface allows you to monitor battery voltage, charging current, internal resistance, cell balance, and other critical information in real time.

Four Independent Charging Channels for Maximum Flexibility

One of the greatest advantages of the ToolkitRC LiPo Charger Q4AC is its four completely independent charging channels. Each channel operates separately, allowing you to charge batteries of different types, capacities, and charge levels at the same time.

When powered by a DC input, the charger delivers up to 50 W per channel, providing a combined output of up to 200 W, making it possible to charge four batteries simultaneously at maximum efficiency. When operating from the built-in AC power supply, the charger provides up to 50 W on two channels or 25 W across all four channels, ensuring excellent flexibility even when an external DC power source is unavailable.

Charging current is adjustable from 0.1 to 5 amps, making the charger suitable for everything from small Tiny Whoop batteries to larger FPV and RC battery packs.

Wide Compatibility with Popular Battery Types

The ToolkitRC LiPo Charger Q4AC supports virtually all commonly used RC battery chemistries. It is compatible with 1–4S LiPo, LiHV, Li-Ion, and LiFe batteries, as well as 1–10S NiMH and 1–8S Pb (lead-acid) batteries. This broad compatibility makes it a versatile charging solution for drones, RC cars, airplanes, boats, and many other RC applications.

The integrated balancing system supports 2–4S batteries, providing up to 240 mA balancing current with outstanding balancing accuracy of better than ±0.005 V. Accurate balancing helps maximize battery lifespan while improving performance and operational safety.

Battery Diagnostics and Internal Resistance Measurement

More than just a charger, the ToolkitRC LiPo Charger Q4AC also serves as a powerful battery diagnostic tool. It measures individual cell voltages within a 0.2–5.0 V range and can accurately measure battery internal resistance from 1–100 mΩ.

Internal resistance is one of the most valuable indicators of battery health. Regular testing helps identify aging or damaged cells before they begin affecting flight time, power output, or overall safety.

Designed for Both Home and Field Use

The charger supports both 100–240 V AC input and 10–18 V DC input, allowing it to operate from a household power outlet or directly from a car battery, field battery, or other DC power source. This makes the ToolkitRC LiPo Charger Q4AC equally suitable for workshop use and field charging during flying sessions or competitions.

An integrated USB 2.0 port also allows convenient firmware updates, ensuring compatibility with future software improvements and additional features.

Compact Design with Professional Features

Despite offering four independent charging channels, the ToolkitRC LiPo Charger Q4AC remains remarkably compact. Measuring only 150 × 112 × 36.5 mm and weighing just 450 g, it easily fits into an FPV backpack or equipment case. The bright IPS display and intuitive menu system make operation simple and efficient for both beginners and experienced RC users.

Its robust construction, precise electronics, and reliable performance make it an excellent choice for everyday charging tasks in demanding environments.
