FLYWOO ToolkitRC M4AC 30W 2.5A AC Smart Battery Balance Charger XT60 Output for 1-4S LiPo LiHV LiFe Battery

The ToolkitRC M4AC is an ultra-compact, intelligent AC-powered balance charger engineered specifically for micro and mini multirotor flight batteries. Capable of servicing Lithium Polymer (LiPo), High-Voltage Lithium (LiHV), and Lithium Iron Phosphate (LiFe) chemistries from 1S to 4S cell counts, this pocket-sized station eliminates the need for external DC power bricks by integrating an efficient AC mainline transformer directly into its lightweight chassis. Outfitted with a high-contrast 1.54-inch IPS LCD telemetry screen for real-time cell monitoring and precise control buttons, the charger delivers exceptionally fine voltage cutoff resolution alongside dedicated XT30 or XT60 hardware output configurations.

Features

Integrated AC Power Topography: Internal transformer hardware allows direct plug-and-play operation from standard AC wall outlets, streamlining bench space and field charging setups by removing heavy external power bricks.

Multi-Chemistry Balance Precision: Sophisticated microprocessor cores monitor independent cell groups from 1S up to 4S, maintaining an exceptionally tight voltage balancing corridor to maximize long-term battery cycle life.

High-Definition Telemetry Display: Integrated 1.54-inch IPS LCD panel provides vibrant, wide-angle visual readouts of real-time cell voltages, continuous charging currents, accumulated capacity metrics, and internal temperatures.

Streamlined Parameter Control: Simple tactile user inputs facilitate rapid adjustments to active charging currents and target cell chemistries, adapting instantly to low-capacity micro whoop packs or heavier mini quad batteries.

Dedicated Hardware Connector Options: Available in distinct production variants featuring native, factory-soldered XT30 or XT60 main power receptors to optimize electrical conductivity and prevent loose connection arcs.

Hardware Variant Configurations

XT30 Mainline Output: Tailored for micro whoops, toothpicks, and lightweight 2S-4S sub-250g aircraft batteries utilizing XT30 power leads.

XT60 Mainline Output: Tailored for traditional 3-inch or 4-inch mini quad battery lines utilizing standard high-current XT60 power leads.

Notes

Balance Lead Mandatory Policy: When charging any multicell pack (2S, 3S, or 4S), you must connect both the primary power lead (XT30/XT60) and the 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 LCD menu strictly matches the physical battery type connected. Charging a standard LiPo pack under the elevated 4.35V LiHV profile will cause immediate cell degradation and poses a severe fire hazard.
