Special features
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.
Input power with 4mm bullet connectors (25A) butt-welded alligator clips and wide input voltage ranges from 10V to 28V. The output power can be adjusted to align with the available input power, thus preventting input current overload and protecting the DC source.
The iCharger series can be used with three types of Lithium batteries - LiPo, Lilo, LiFe - and has a fully integrated cell balancer.
Internal temperature sensor and temperature controlled automatic cooling FAN controls the internal temperature and provides intelligent protection. When the internal temperature is over 60 (140 oF), the output power is automatically reduced by 25%. If the temperature exceeds 65 (149 oF) the charge cycle is stopped.
Convenient set of 10 battery profile memories that can be saved and loaded by number.
2x16 backlit LCD screen that provides rich information including active mode, current, voltage, total charge (mAh), charging time and temperature etc.
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.
Up to 300w unique regenerative discharge capability. Regenerative discharge takes most of the output battery‘s energy and puts it back into the input battery, which is not the same with the traditional methods of discharge to deplete that energy in the form of heat across a transistor. That is, when you discharge your LiPo for storage, you will be re-charging your Lead Acid input battery. The amount of current and voltage that your input battery can accept limit the total amount of power that you can achieve, or 300W, whichever is lower.
Unique Lithium battery expanding discharge program. When you connect the external capacity resistance, you can use it as the maximum discharge power capacity—600W (@30V/20A).

iCharger Synchronous Balance Charger/Discharger |
206B |
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.
Electric motor test mode can be used to run-in electric motors, test motor parameters and performance, check tolerances etc.
Foam-cut drive. In this mode, the charger acts as a convenient power supply for a hot wire foam cutter.
Battery interior 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.
iCharger 206B has a 16Mbit flash storage, which can log offline charge and discharge data in 36 hours.
Support upgrading the hardware program by USB port. The iCharger also support the ―logview‖ software and can display, plot and analyze the charge and discharge data by it. (See detail information about logview in the following website: http://www.logview.info)

Warnings and Safety notes
Keep the charger away from children and pets at all times.
Never leave the charger unsupervised when charging or discharging. If you leave, disconnect the battery to prevent any unexpected dangers or damage.
Ensure the charger program and settings match the battery pack otherwise the battery will be damaged and a dangerous situation may arise, especially for Lithium batteries, which may cause a fire.
Do not mix batteries of different types, different capacities or from different manufacturers.
Do not disassemble the charger.
Do not place the charger or any battery on a flammable surface or near a combustible material while in use. Do not charge or discharge on a carpet, cluttered workbench, paper, plastic, vinyl, leather or wood, inside an R/C model or inside a full-sized automobile.
Never block the air intake holes and never use in a refrigerated or high temperature environment. If used in such an environment, the internal temperature protection may result in abnormal charging/discharging that could be dangerous.
Do not allow water, moisture, metal wires or other conductive material into the charger.
Never charge or discharge any battery having evidence of leaking, expansion/swelling, damaged outer cover or case, color-change or distortion.
Do not try to charge ―non-rechargeable‖ dry cells.
Do not exceed the battery manufacturer‘s suggested maximum charge rates.
Beware that the external case temperature of the charger will increase during charging/discharging at high power.
Carefully follow the battery pack manufacturer‘s recommendations and safety advice.
Recommended connecting way:
1.Connect iCharger's input power supply, and turn on it.
2.Connect Li batteries' balance port
3.Connect the main charging port's positive pole to cells' positive pole, and then connect negative pole to cells' negative pole (this will avoid striking fire while connecting Li cells).
4.Start charging and discharging...
5.After finishing charging and discharging, pls disconnect the cell and charger, and then turn off the charger's power supply.

User parameter setup initial display.
iCharger checks the cell count of Lithium batteries automatically at the beginning of the charge or discharge process in order to detect and avoid erroneous setting by the user. However, deeply discharged batteries can be perceived incorrectly. To avoid this problem you can set an initial time during which to charge the battery at a low current, usually 100mA. Normally 10 minutes is enough to detect the cell count correctly. For batteries of different capacities, you should adjust the time delay. Note: If you set the time delay too long for a low capacity battery then the charging process can be finished within the time delay with an erroneous cell count, which may damage the battery and could be dangerous.
Range: 1 – 10 min. (1min, default)
For balance charging Lithium batteries. If the Bal. Speed is set to Fast, the CV termination current will be higher, the charging time shorter and the per-cell voltage lower. When set to Slow, the CV termination current will be lower, the charging time longer and the per-cell voltage higher. The default value of Normal is between the Fast and the Slow. If Bal. Trickle is ON, the iCharger won‘t stop charging until the current falls to around 20mA.
Bal.Speed: Fast, Normal & Slow, (Normal, default). Bal.Trickle: OFF & ON: (OFF, default)
For balance charging Li battery. There are three balance modes options: CV phase, storage voltage and always. If the balance mode is set to CV phase, when any cell‘s voltage reaches the set voltage for CV, it will enable the balancer. When set to ―always‖, the balancer will be enabled from the beginning of the charge process. When set to ―storage voltage‖, the balancer will be enabled when any cell‘s voltage exceeds the default storage voltage for the configured chemistry.
Balance mode: CV phase, storage voltage, always (CV phase, default)
When running a charge/discharge cycle program for a Lithium, NiMH or NiCd battery the charger will stop for a while before continuing to the next phase. This allows the pack to cool down.
Range: 1 – 60 min. (10 min default)
You can turn post charge-completion trickle charging. On or Off for NiMH, NiCd or Pb batteries.
Range: OFF, 10 – 500mA. (OFF,default)
Usually, the NiMH battery voltage will drop a little right after reaching full charge. This is known as - V. You can alter the iCharger‘s delta-peak detection sensitivity.
Range: 1 – 20mV/Cell. (4mV/Cell, default)

Input voltage protection lower limit. The charging/discharging process will stop immediately if the input voltage falls below the set value.
Range:10.00 – 25.00V (10.00V, default) Current Range: 1.0A – 22.0A(22.0A, default)
Note: Current limit is not very accurate, which may be 20% difference, max.
Charge/Discharge power limit. The maximum charge/discharge power of iCharger can be adjusted in order to limit internal temperature and to protect the input current from over-loading. When the limit is set to AUTO the iCharger can adjust the output charging power according to the input capability.
CHG: 50 –300W and AUTO. DCHG: 5 –20W
Note: The maximum charge power capacity is also limited by input current. The maximum input current of 206B is about 21A, and Wmax ≈ Imax * Vin * 90%. (For example, when the input voltage is 11V, the maximum charge power capacity ≈21×11×90 207W).
