Junsi iCharger 4010DUO Multi-Chemistry DC Battery Charger (10S/40A/2000W)
The 4010DUO uses advanced high current and high-performance synchronous buck-boost DC/DC converter technology to deliver up to 2000W of charging power, with a maximum charge/discharge current of up to 40A per channel and two channels in Synchronous Mode up to 70A! Each channel supports 10S lithium batteries, while the impressive TFT LCD screen provides critical battery information including current, voltage, power, capacity, internal resistance, control status, time-consuming, temperature, and more. 64 parameters sets can be saved without repeat settings, simply import/export via an SD card. The 4010DUO applies a 1.2A balance current, and uses a unique "internal resistance correction" balance calculation, and the discharge features include discharge-self, regenerative to input discharge, regenerative to channel discharge, and lithium battery extra expanding discharge. Plus, the 4010DUO can measure not only the internal resistance of the entire battery pack, but also measure the internal resistance of the individual cells within the battery.
Internal temperature protection keeps the charger operating safely and efficiently. When the internal temperature exceeds the threshold, the output power is automatically reduced and the charger will shut down when the temperature exceeds the cut-temperature. The intelligent fan control senses the internal temperature and uses an internal temperature sensor to control the fan speed. The 4010DUO has protection for reversed polarity (input or output), input voltage/current, battery temperature, charging capacity, time overrun, maximum power and more, while the multi-discharge features include discharge-self, regenerative to input discharge, regenerative to channel discharge, and lithium battery extra expanding discharge. The hardware programming can be updated through the USB port. The 4010DUO also supports “Logview” software to display, plot and analyze the charge and discharge data.
