Junsi iCharger 456DUO – High-Power Dual Channel Charger
The renowned manufacturer Junsi has completely redesigned its popular 406DUO charger with the all-new iCharger 456DUO, combining proven performance with the latest technology. At Aerobertics, we’re excited to bring you this advanced charger that pushes the limits of what’s possible in model battery management.
Unmatched Performance & Power
The iCharger 456DUO merges the strengths of the 406DUO with cutting-edge enhancements, delivering more power, more versatility, and smarter features. Both charging outputs are equipped with high-current XT90 connectors to safely handle sustained high currents.
- Maximum charge power: 2200W (above 40V)
- Cell compatibility: 1–6S LiXx (LiPo, LiHV, LiIon), NiMH, NiCd, NiZn, PB (lead-acid)
- Maximum charging current: 45A per output, 70A in synchronized mode
- High-accuracy balancing: 4A total (2A per output) for perfectly balanced cell voltages
Whether you’re charging small packs or high-capacity batteries, the 456DUO has the power to get the job done safely and efficiently.
Advanced Discharge & Regenerative Capabilities
- Standard discharge power: 140W total (80W per output if used individually)
- External high-current discharge: Up to 2200W
- Regenerative charging: Recycle battery energy back into your supply system—for example, from a fully charged flight pack into a service battery
Smart Connectivity & Features
- USB-C PD port: Charge smartphones or tablets and perform software updates (5V/3A, 9V/2A, 12V/1.5A)
- Micro SD slot: Log data or update firmware
- Digital Power mode: Use one output as a stabilized power supply with adjustable voltage (2–32V) and current (1–45A)
- Integrated servo tester: Requires external power supply
User-Friendly Design
The interface follows the familiar layout of the Junsi iCharger 308DUO, 406DUO, and 4010DUO. A bright 2.8” IPS LCD display ensures easy readability even in low-light conditions.
Safety & Compatibility
All Junsi X and DUO series chargers are designed exclusively for model use. Industrial applications are strictly prohibited. Only connect to model-grade power supplies. AGM batteries must not be charged using the PB program.
Important: Always set the correct input voltage to avoid damage not covered by warranty. For example, if your power supply provides 600W at 24V:
- Input voltage: 24V (-2 to +3V)
- Current limit: 25A
- Maximum charge power: 600W
