This is a Junsi Electronics iCharger 306B+ DC Battery Charger.This charger allows you to charge and balance 2S to 6S lithium batteries. The charger comes with XH style balance connectors on the side of the charger that fit Align, E-Flite and ProTek R/C battery packs. Adapter boards for other batteries are also available.

  • High power, high current, high-performance power conversion circuit. The iCharger series uses advanced Synchronous buck-boost DC/DC converter technology with an output conversion efficiency that can reach over 90%. This not only saves power and reduces heat build up but also makes the charger more compact and conveniently mobile.
  • Two input power choices. DC jack with auto-resetting fuse and alligator clips that can be soldered to the main input leads.The output power can be adjusted to align with the available input power, thus preventing input current overload and protecting the DC source.
  • Multiple Battery Types. The iCharger series can be used with three types of Lithium batteries - LiPo, Lilo, LiFe - and has a fully integrated cell balancer.
  • 10 memory slots. Convenient set of 10 battery profile memories that can be saved and loaded by number. You can also set the name on the memory slots to a custom value for easy identification.
  • Large backlit LCD screen. 2x16 backlit LCD screen that provides rich information including active mode, current, voltage, total charge (mAh), charging time and temperature etc.
  • Charge/Discharge options. Various charging/discharging settings and cycles to meet a wide range of customer needs. For Lithium batteries: balance charging, normal charging, fast charging, storage, discharging, ext-discharging, charge/discharge cycling, and battery monitoring. For NiCd/NiMH batteries: charging-auto, charging-manual, discharging, charge/discharge cycling and forming charge. For Pb batteries: charging and discharging.
  • Unique Lithium battery expanding discharge program. When you connect the external capacity resistance, you can use it as the maximum discharge power capacity—1200W (@40V/30A).
  • Unique Lithium battery Monitor program. When you use other equipment to charge or discharge a Lithium pack, you can use the iCharger to monitor the per-cell voltages, battery temperature and process time. If any individual cell appears over-charged or over-discharged or the pack is too hot or the process has gone on for too long, the iCharger will generate an alarm sound and the related information will blink.
  • Battery internal resistance measurement. The iCharger can not only measure the internal resistance of the battery pack, and also can measure the per-cell internal resistance (only available for lithium battery).
  • Perfect protection. The iCharger has protection for reversed polarity (input or output), low input voltage, battery temperature, charging capacity and time overrun.

The iCharger also supports the “Open Format” data of the “logview” software and can display, plot and analyze the charge and discharge data (See detailed information about logview in the following website, http://www.logview.info). To download the product manual click here.

Junsi iCharger 306B Lilo/LiPo/Life/NiMH/NiCD DC Battery Charger (6S/30A/1000W)
Now this is a charger, yes sir. I calibrated this with a multimeter, set it to slow balance mode, and use a 1200 watt 24V power supply on its own dedicated outlet. I recommend to the same to get the full effect from this amazing charger. I charge (8) 22.2volt 3300 batteries on daisy chained parallel boards. The batteries measure out exactly 4.20 per cell. The batteries will not drop voltage as soon as they come off the charger- they are truly leveled off at the voltage. I charge them with 23A and am blown away to see the charger inputting 24A to do it. Do not crank on this charger with less than 24V input or an overloaded circuit. Other than that, I'm sure this thing will last a long time. It's super efficient and the wires and unit do not even get warm. I would charge at the full 30A but notice the batteries are better balanced and accurate with a more conservative charge rate.

I got this charger as a back up for my i Charger 106B+. It functions pretty much the same as my 106B+. I cant recommend Junsi iChargers enough

I've been using this charger for 7 years now to charge RC Aircraft and Car batteries. It's been fantastic and I would happily replace it with another the same if it ever died on me.

This charger is by far the best in it's class. I acquired mine from a friend who took very good care of it. Going on three years old and is flawless and very accurate. Currently paired up with an 875 watt HP power supply. If this thing ever does croak I'll buy another.
