Transform the way you charge your high-capacity packs up to 8S with our state-of-the-art RDX2 1600 Duo AC/DC multi-function battery charger. This all-in-one powerhouse features a built-in power supply and dual charging capabilities, delivering up to 1600 watts on DC and 500 watts on AC. It provides an impressive output power of up to 32 amps per port for your demanding RC needs. For rapid pit stops, the reverse discharging feature allows you to discharge your battery quickly and safely at the track or back at the workshop.
Key Takeaways for Your Large-Scale Fleet
- Maximize 6S & 8S Packs: Perfect for 1/5 scale bashers or giant-scale planes

Max Charging Amps: Single Port vs. Parallel Combined Mode
The chart below breaks down the maximum available charging current per port for LiPo batteries (using 4.2V per cell for maximum wattage math). When parallel charging, the charger combines its internal power pools to achieve a maximum ceiling of 50.0 Amps, pulling from either a 500W limit on internal AC or the full 1600W limit on an external DC supply.
