Setting up the charger was straightforward. It plugged directly into a standard AC outlet, and the connection felt secure. The blue tack suggestion to prevent glare on the screen was appreciated and proved effective. The overall design is sleek and functional.

The initial startup and detection of my 6S LiPo battery were quick and seamless. The charger intelligently identified the battery's specifications, simplifying the charging process considerably.

Charging Performance and Ease of Use

The charging process itself was incredibly simple. Using the scroll wheel, I quickly navigated to the charging menu and selected LiPo. The charger automatically detected the number of cells and voltage. Selecting the 1C charge rate was intuitive and the charging commenced immediately.

The display provided a clear and concise summary of charging parameters. Real-time information, including voltage, current, and individual cell voltages, was readily available. The progress was easy to monitor, eliminating any guesswork.

The balance charging feature worked efficiently, as indicated by the flashing amber lights on the display. The charger intelligently balanced the cells, ensuring even charging across all cells. The whole experience was smooth and hassle-free.

Features and Specifications

The M8AC boasts a powerful 600W charging capability, achieved either through its internal 200W AC power supply or an external 7-35V DC power source. This flexibility makes it adaptable to various charging scenarios.

Beyond charging, the M8AC is a multi-functional tool. It integrates a signal generator, signal tester, ESC tester, and an adjustable power supply. The inclusion of a dedicated DJI drone battery charging mode is a significant advantage for drone enthusiasts.

Advanced Features and Battery Compatibility

The M8AC supports a wide array of battery chemistries, including LiPo, LiHV, LiFePO4, LiIon, LTO, NiMH, and Pb. The inclusion of a dedicated UAV battery charging mode simplifies charging DJI drone batteries. This feature supports a large number of DJI models, making this charger extremely convenient for drone pilots.

Various charging modes are available, including charge, discharge, storage charge, and a ‘destroy’ function for safely discharging damaged batteries. The ability to set the end voltage and charge current provides flexibility and precise control.

The discharge mode, while primarily internal, could be enhanced by adding external discharge capabilities similar to previous ToolkitRC chargers, allowing for battery-to-battery charging.

Multi-Functional Capabilities

Beyond its primary function as a charger, the M8AC functions as a versatile testing and diagnostic tool. A six-pin port allows for connection to servos and other components for signal measurement and generation.

The charger can measure resistance, signals (PWM, SBUS, etc.), and generate signals for testing purposes. This feature is incredibly useful for troubleshooting RC components.

Additionally, the M8AC can be used as a variable power supply, providing a convenient power source for various projects or bench testing. This multi-functional aspect significantly increases its value and utility.

Conclusion and Verdict

The ToolkitRC M8AC is a powerful and versatile charger offering exceptional value for its price. Its 600W charging capability, ease of use, and multi-functional features make it a compelling option for RC enthusiasts.

While the lack of external discharge capabilities in the current iteration is a minor drawback, the overall performance and features outweigh this limitation. The improved balance charging accuracy and the dedicated DJI drone charging mode are notable highlights.

Overall, the M8AC is a strong contender, though its single-channel charging versus the dual-channel M6D AC remains a consideration. The M6D AC's convenience for simultaneous charging might be preferred by some users, but the M8AC’s power and multi-functionality make it a superb choice for many.
