  • Each channel supports 6s LiPo, Lilo, LiFe and NiZn batteries, with maximum 1.2A balance current, and adopts a unique balance calculation of internal resistance correction. Supports 1-20s NiMH/NiCd batteries and 1-12s Pb batteries.
  • With 1A/5V USB charging port, convenient for the user to charge mobile phones and PCs.
  • When the channel output connects the battery after the charger powers on, it will start automatically the anti-sparking protection.
  • Intelligent fan control. Sensing internal temperature via the internal temperature sensor, to thereby control the fan speed.
  • Internal temperature protection. When the internal temperature exceeds the Power Reduce temperature, the output power is automatically reduced; and the charger will shut down when temperature exceeds the Shut-down temperature.
  • This charger can save 64 parameters sets and support the data import/export to SD card.
  • A 2.8-inch LCD screen provides rich information including current, voltage, power, capacity, internal resistance, control status, time-consuming and temperature, etc.
  • Multi-discharge features: self-discharge, regenerative to input discharge, and lithium battery extra expanding discharge.
  • Supports measurement for internal resistance of battery offline and online. Can measure not only the internal resistance of the entire battery pack, but also measure the internal resistance of each cell within the lithium battery.
  • The iCharger has protection for reversed polarity (input or output), input voltage/current, battery temperature, charging capacity, overrun time and maximum power etc.
  • Supports upgrading the hardware program by USB port or SD card. The iCharger also supports the “Logview” software and can display, plot and analyze the charge and discharge data by it.

Junsi iCharger 406DUO Lilo/LiPo/Life/NiMH/NiCD DC Battery Charger (6S/40A/1400W)
Love my icharger. This unit is great, 2 charger ports and the size of 1 charger. Amazing accuracy and for me, peace of mind when charging. The menu logic is a little tricky to navigate at first, knowing which buttons to get into menu and then the push/click wheel...but I got it finally. Very happy and worth the $$.)

If you want one of the best chargers on the market, look no farther than one of these awesome iChargers.
My FMA power lab 6 has all the abilities this one does, but the iCharger is hands down the winner in build quality and user friendliness with a very clear to read backlit color screen to boot.
The specs on this bad boy is more than most people would ever need in most situations. EXACTLY! (Tim Allen grunting!)

Even has a 5v 1 amp USB on the back so you can charge a phone.
Has a micro usb to PC communications input as well as a micro SD socket for saving raw data.

The one thing to note is how much smaller this charger is that what I expected it to be, even when looking at videos and pics it just looks much larger than it actually is. It is roughly 2/3 the size of my powerlab 6, yet has two channels.)
