M7AC AC/DC Smart Battery Charger with Balance Charging and IPS Display for 1–6S Lithium Battery Packs

The M7AC is an AC/DC smart charger for rechargeable battery packs, with balance charging, XT30 and XT60 charging outputs and a 2.4-inch IPS display. Its integrated AC supply and separate DC input support bench or field setups, while measurement and signal functions add tools for RC electronics.

Key Features

• Charges 1–6S LiPo, LiHV, LiFe, lithium-ion and LTO packs, 1–16S NiMH packs and 1–10S lead-acid packs.
• The integrated AC power supply is rated at 100W; a separate 7–28V DC input supports compatible external power sources.
• XT30 and XT60 charging outputs and balance charging support compatible packs.
• The color IPS screen, scroll wheel and customizable voice alerts provide control and charging feedback.
• Electrical measurement includes pack voltage and internal resistance, plus PWM, PPM, SBUS and ESC testing functions.
• Signal generation and an adjustable CC/CV power supply extend its use beyond charging.
• A 5V USB output provides up to 10W and supports firmware upgrades; an SD slot is also listed.
