Charger Junsi iCharger 306B

Make sure your batteries are perfectly cared for and ready for flight as quickly as possible. The Junsi iCharger 306B charger is a high-performance single-channel charger capable of operating at up to 1000W. The device supports the widest range of battery chemistries, including LiPo, LiFe, LiIon, LiHV (up to 6S), 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. This is an ideal choice for serious pilots who need to service large numbers of batteries quickly and safely.

• Huge power of 1000 W. Allows you to charge batteries with a capacity of up to 50,000 mAh with a maximum current of up to 30 A.

• Regenerative discharge with a power of 350 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 (1-6S), NiMH/NiCd (1-17S), Pb (1-12S) for complete versatility.

• Synchronous rectification technology. Provides efficiency up to 90%, 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 306B 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 90%, 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 350 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 306B has 50 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 50 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.
