ToolKitRC M7AC 100W/300W Charger with Power Supply

The ToolkitRC M7AC DUO is a highly versatile, multi-function smart balance charger and signal diagnostics station engineered to deliver robust power management and hardware testing capabilities for radio-controlled (RC) and FPV drone flight batteries. Featuring a flexible dual-input AC/DC power infrastructure, this multi-channel station eliminates the need for external power bricks on the bench while transforming into a high-amperage powerhouse out in the field. Outfitted with a high-contrast 2.0-inch IPS LCD screen, dedicated multi-protocol signal generating test beds, and high-capacity regenerative discharging pathways, the M7AC DUO serves as both a comprehensive charging hub and an advanced receiver telemetry diagnostic tool.

Features

Flexible Dual-Input Topography: Houses an internal AC transformer for efficient, self-contained bench setups directly from wall mainlines, while natively supporting a wide-range DC input port for maximum field performance.

Signal Diagnostic & Testing Core: Multi-functional hardware output array generates and captures precision PWM, PPM, and SBUS protocol streams, allowing pilots to test receiver functions, calibrate Electronic Speed Controllers (ESCs), and diagnose servo behavior without standard radio gear.

Advanced Regenerative Discharging: Supports heavy-duty recycling loops that route energy from discharging batteries back into a high-capacity DC field source at up to 300W, minimizing localized heat generation and preserving field energy reserves.

Vibrant IPS Telemetry Display: Integrated 2.0-inch IPS LCD panel provides wide-angle visual readouts of real-time cell voltages, internal resistance values, and continuous operating current curves with excellent outdoor readability.

Expandable TF Data Architecture: Integrated MicroSD/TF card slot supports storage capacities from 128MB up to 16GB, facilitating extensive telemetry data logging, historical cell performance tracking, and rapid system firmware updates.

Auxiliary Power Output Terminal: Outfitted with a standard 10W USB Type-A accessory port designed to efficiently recharge mobile devices, field monitors, or peripheral flight gear on the bench.

Notes

AC vs DC Input Dynamics: To exploit the full 300W total charging throughput and 15A current velocities, the charger must be supplied with an optimal DC power source within the 7V–28V range. When operating strictly on an AC wall outlet, dynamic internal power scaling will cap the overall maximum output capacity to 100W due to transformer limits.

Balance Lead Mandatory Policy: When charging any multi-cell lithium pack (2S through 6S), you must connect both the primary high-current output lead and the corresponding white JST-XH balance connector simultaneously. Attempting to charge multi-cell series lines without individual channel balance telemetry bypasses critical safety overrides and can cause severe cell over-voltage, localized battery expansion, or thermal hazards.

Proper Chemistry Selection Target: Always verify that the selected chemistry profile on the digital menu strictly matches the physical battery type connected. Charging a standard 4.20V LiPo pack under the elevated 4.35V LiHV profile will cause immediate cell degradation and poses a severe fire hazard.
