Battery Charger TOOLKITRC M6AC — AC 100W / DC 300W, smart charger for batteries and power systems

High-quality M6AC AC/DC balance charger with microprocessor-controlled charging, discharging, cell balancing, signal measurement and adjustable power supply functions. The charger supports the main battery chemistries used in RC models—LiPo, LiHV, LiFe, Li-ion, LTO, NiMH and lead-acid—and can be powered from AC mains or a DC source. The unit includes a USB Type-A fast-charging output and a 2.0" color IPS display for clear status monitoring.

Advantages

The M6AC combines a balance charger, discharger, signal analyzer/generator and adjustable DC power supply in one compact device. It provides up to 1000 mA balancing current for fast and accurate cell balancing, supports both AC and DC input, and delivers high charging power in DC mode. The charger includes multiple protections (over-voltage, over-current, short-circuit, reverse polarity, overheating, low input voltage, timeout, cut-off) and allows firmware updates. Built-in connectors and a clear 2.0" IPS LCD make it suitable for workshop and field use.

How to use

Connect the charger to an appropriate power source: AC mains (100–240 V) or a DC supply (7–28 V). Attach the battery to the proper balance and output connectors (observe correct polarity) and select the matching battery chemistry and cell count on the device. Set the desired charge/discharge current and any CC/CV parameters if using the unit as a power supply. Monitor voltage, cell balance and internal resistance via the 2.0" IPS display during the process. Use the signal port to analyze or generate PWM/PPM/SBUS signals when testing transmitters, receivers or servos.

Recommendations

For safe and reliable operation, verify connector polarity before connecting batteries, use appropriate charging settings for the specific cell chemistry and count, and ensure adequate ventilation during high-power charging or discharging. Update firmware when updates are available and keep the device dry and clean.
