IFLIGHT M4 AC 30W 1-4S XT30 Charger

The iFlight M4AC is an ultra-compact, intelligent AC-powered balance charger engineered specifically for micro and mini multirotor flight batteries utilizing an XT30 power interface. 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 dedicated physical control inputs, the charger delivers exceptionally fine voltage cutoff resolution alongside a native XT30 hardware output configuration.

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, and total capacity metrics.

Tactile Parameter Control: Simple structural user buttons facilitate rapid modifications to active charging currents and target cell chemistry profiles, adapting instantly to low-capacity micro whoop packs or heavier mini quad batteries.

Native XT30 Interface: Features a native, factory-soldered XT30 main power receptor tailored for sub-250g aircraft, optimizing electrical conductivity and preventing loose connection arcs.

Automated Charge Initiation: Once battery parameters are verified by the internal safety checks, the charging cycle kicks off automatically to provide a seamless plug-and-charge user experience.

Operational Instructions

Mainline Power Setup: Connect the heavy-duty AC power cable to a wall outlet. Upon terminal boot-up, the primary digital telemetry interface will illuminate.

System Startup Unlock: Every time the device is powered on, you must manually tap the control button to unlock the user interface before setting up a charging loop.

Chemistry Cutoff Selection: Press and hold the control button for 2 seconds to enter the settings menu and choose the correct target voltage cutoff matching your battery chemistry.

Current Parameter Adjustment: Press the control button simultaneously/in sequence to cycle through and modify the desired output charging amperage.

Cycle Execution: Connect your flight pack to both the primary XT30 power port and the corresponding JST-XH balance port. The charger will evaluate the active cell voltages and automatically initiate the charging profile once conditions are verified as safe.

Notes

Balance Lead Mandatory Policy: When charging any multi-cell pack (2S, 3S, or 4S), you must connect both the primary power lead (XT30) 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.

Deployment Environment Restrictions: Operate the unit strictly within its designated AC input limits. Do not deploy the charger in areas exposed to high temperatures, heavy moisture, or in close proximity to flammable or explosive materials. Always disconnect the mainline AC plug when the charger is sitting idle on the bench.
