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.

Features:

  • 1400W of charging power per channel, 2000W when both channels are combined
  • Maximum charge current of up to 40A in Asyn. Mode, 70A in Sync Mode
  • Maximum discharge current of 130W per channel, 200W when both channels are combined
  • Each channel supports 10S lithium batteries
  • TFT LCD screen displays current, voltage, power, capacity, internal resistance, control status, time-consuming, temperature and more
  • 64 parameter sets can be saved
  • Measures internal resistance of the battery pack, and also the per-cell internal resistance 
  • 1.2A balance current, and uses a unique "internal resistance correction" balance calculation 
  • Internal temperature protection
  • Intelligent fan control
  • Multi-discharge features: discharge-self, regenerative to input discharge, regenerative to channel discharge, and lithium battery extra expanding discharge.
  • Supports upgrading the hardware program by USB port
  • Supports “Logview” software to display, plot and analyze charge and discharge data

I love this Charger! I have been ARF flying park flyers for over a decade and know almost nothing about batteries and charging them. All my experience has been just plug the battery that came with the plane into the charger that came with the plane and fly, but this charger is so easy, I can use it. It seriously requires pressing enter like 4 or 5 times and your batteries are charging right up! I can see all this information about the batteries and I am learning so much in the process. I bought this charger because I am terrible about taking care of my batteries and keeping them charged. I normally just spend the entire day charging a pile of dead batteries so I can fly that evening. This thing charges all my batteries at the same time (literally 40+ all at once, multiple types and builds), it's crazy. I love this thing! It's built very solid and they paid attention to every detail. Even the wires they sent are 10AWG and come pre tinned! I highly recommend, regardless of skill level.

Best charger on the market, period. Worth the money if you have a large collection of various battery chemistries, capacities and voltages.

Works great, love the features and accuracy. I've owned other high-end chargers and this one blows them away! Everything about it is perfect, other than one thing. The balance wires fit extremely tight, so be vary careful removing them, to not tug on the wires. Granted this shouldn't be a problem, keep them on. I'd recommend you read the manual. To make sure you install the balance wires positive and negative connections correctly, plug them first into the balance boards. (They are marked + (Red wire) and - (Black wire) Else you can install them backwards. Not sure what this would do but I'm pretty sure it would be bad.

Have been using one for years, just don't keep putting the screen up and down each use, prone to ribbon breakage I have been told, a slight learning curve to program all the various settings but enough people have them and are willing to advise, as well a videos.

Have been using 2 of the 460 duo chargers in my race pits for about 5 years, they performed very well. I decided to up grade the the 4010. They are a great upgrade and so far do everything i need on my drag packs. 40A charge and discharge my lipos with programming and a resistor that processes is a snap. They are a little bit expensive but in this case you get what you pay for. I have and do recommend to anyone looking for a top of the line charger.

I've had this charger about two weeks and so far it's been great! My largest packs are only 6 cell 5000's. It's a breeze to operate and has tons of information displayed on a color screen. I feel more in control of my batteries with this charger. I just finished running all of my batteries through a "balance" and they are all in great condition now. The charge is uneventful and quick but also informative with regard to each cell. I've been able to put my least or non usage batteries in a storage mode and keep my current sets in great condition. Try it, you will like it!

What can I say? These chargers actually work! They will balance charge 2 6s 5000 batteries at 1.5C in about 20 minutes. My old charger could not get to even 5 amps at 6s. It would let you set the charge that way and would proceed to only charge at 4amps. You can't go wrong here. This is the flagship model from Junsi.

My Junsi ICharger 4010 Duo is by far the finest and easiest charger I’ve ever owned, I would not have any other! I have the I-6, the Reedy 1226-C2 and a power hobbies 200 watt duo. The 4010 duo is magic! Love it!
