Charger Junsi iCharger 208B

Give your batteries quick and safe care for maximum performance. The Junsi iCharger 208B charger is a high-performance single-channel charger capable of operating with power up to 350 W. The device supports the widest range of battery chemistries, including LiPo, LiFe, LiIon, LiHV (up to 8S), NiMH, NiCd and Pb lead acid.

Innovative synchronous rectification technology ensures high efficiency, and the regenerative discharge function allows you to safely discharge batteries by returning energy to the external load. It's an ideal choice for serious pilots who need to maintain high voltage batteries quickly and safely.

• High power 350 W. Allows you to charge 1-8S batteries with a maximum current of up to 20 A.

• Regenerative discharge with a power of 100 W. Safely discharges storage batteries by dissipating energy into an external resistor or returning it to the source.

• Supports all popular chemistries. LiPo/LiFe/LiIon/LiHV (1-8S), NiMH/NiCd (1-17S), Pb (1-12S) for complete versatility.

• Synchronous rectification technology. Provides efficiency up to 94%, minimizing heating and energy loss during operation.

• Advanced security features. Temperature control, timer, capacity limitation and automatic error shutdown for maximum safety.

Working principle and advanced technology

Junsi iCharger 208B is a microprocessor charger that operates from an external DC power supply. It takes energy from a power supply (purchased separately) and converts it to charge batteries with pinpoint precision. Synchronous rectification technology allows the device to achieve efficiency of up to 94%, which significantly reduces heat and energy loss compared to traditional linear chargers. This is especially important when dealing with high currents, as the device stays cooler and lasts longer.

The Regenerative Discharge function allows batteries to be discharged to storage voltage with a power of up to 100 W. Instead of simply dissipating energy as heat, the device can direct it back to an external power source or load. This is not only safe, but also effective, since the discharged energy is not wasted. For precise settings, the iCharger 208B has 20 memory locations to store different charge profiles.

Technical characteristics and functionality

The device allows monitoring and control from a computer via an optional USB adapter and LogView software. Built-in memory for 20 profiles allows you to save settings for different types of batteries, which saves time when switching between different models. Several operating modes, including cycling (charge-discharge) and storage (Storage), extend battery life. High accuracy of voltage measurement up to 0.01V guarantees perfect balancing of each can.
