    This charger is a analyzing LiIon and NiMH charger, this means the charger can both charge and discharge while measuring. The total number of function is large and this means the technical section in this review is very large.

    DSC_4844 

    When the charger is turned on, it displays test where all the text can be seen. 
    When startup is finished it is possible to select mode:
    • CHARGE: Charge battery with 200 to 1000 (2000) mA.
    • DISCHARGE: Discharge battery with 200 to 1000 mA.
    • DISCHARGE REFRESH: Discharge and charge the battery 3 times.
    • CHARGE TEST: Charge, discharge and charge the battery, show how much current was discharged.
    • QUICK TEST: Measure the internal resistance of the battery.


    When display is flashing it is possible to select mode and current.
    Using the slot button it is possible to reselect a slot and change parameters for it, also when charger is working.
    When putting multiple batteries in the charger at the same time, it is possible to select mode and current simultaneous for all of them (Very nice).

    When charging or discharging it is possible to use the DISPLAY button to select between V, mA and mAh.
    The display button can also be used when the charge/discharge is finished, but the charger will change back to "full" display rather quickly.

    DSC_4830

    Here is an example where I have selected different functions for each slot.

    DSC_4841

    Each time a button is pressed, the light turns on for a 20 seconds.
    The FULL and NULL message can also be seen.

    DSC_4725

    The charger uses an external 12 volt power supply at 3A (see later).
    It has a fan, this is necessary to handle all four channels at full power. Even with only one channel in use the fan, it start and stop very often. The fan is not very loud, but due to the starting and stopping it is very annoying.

    DSC_4727 DSC_4729 

    The charger uses the classical slider construction to handle most battery sizes. The slider works smoothly and can handle sizes from 32 mm to 72.5 mm.
    For measuring internal resistance the slider is not very good, it often has a "high" connection resistance.

    DSC_4739 

    A couple of different NiMH batteries in the charger.

    DSC_4740

    And some LiIon batteries.

    Using only slot #1 and/or #4, the maximum charge current is 2000mA.
    In all other cases the maximum charge current is 1000mA.
    The maximum discharge current is always 1000mA.

    Charge currents: 200, 300, 500, 700, 1000, 1500, 2000
    Discharge currents: 200, 300, 500, 700, 1000

    DSC_4734 DSC_4735 DSC_4736 DSC_4737 DSC_4738 

    The charger can easily handle 
    70 mm long batteries
    It is recommended to charge smaller batteries in the two center slots.
    The charger has an internal switch marked with 3.7V, 4.20V and 4.35V. I have not tested this switch, because it is internal, but it might be possible to charge other LiIon chemistries.

    Measurements

    • The LCD background light turns off 20 seconds after the last keypress.
    • The charger has very high current spikes from the supply.
    • When charging 1 battery at 0.5A the fan turns on/off all the time, it is very annoying when sitting close to the charger.
    • When charging 4 batteries at 1A the fan runs continuous.
    • It will discharge NiMH batteries with up to 0.8mA when not charging.
    • It Will discharge LiIon batteries with up to 2.1mA when not charging.
    • Power cycling will restart charging.
    • Reinsertion of batteries will restart last mode selected.
    • Falling voltage will not restart charging.
    • When batteries are put in and no buttons is pressed a 0.5A charge will start.
    • Voltage is measured with current off and is within 0.01 volt.
    • Voltage display is updated once a minute.
    • When charger is powered on it always starts in charging mode with 0.5A selected.
    • While power is on it remembers last mode selection, but will always start at 0.5A.

        Good charger
        Pros:
        This is an older version of the opus charger I looked everywhere for review\'s and I saw that it is the same version as the new charger but has problems when charging 4 cells at once; so I haven\'t charged 4 cells at once. Good price on good charger if you don\'t need to charge 4 cells at a time.

        best value-for-money charger/analyzer
        Pros:
        Four-channel, fully-independent bay, regardless of what is the mode used in a bay, the next bay can do another mode independently (ie: charge/discharge/cycle/test/IR test, etc) and also for niMh, li-ions, etc.....also has 4.35v capability
        Cons:
        fan noise can be disturbing to guys used to chargers without active cooling.

        Pros:
        Блок питания, вентилятор. Блок питания если и нагревается то весьма умеренно. Вентилятор включается и выключается по надобности. В тихой комнате на расстоянии в метра 3-4 вентилятор слышно. Я бы не назвал звук противным, но от есть — прислушиваться к сожалению не надо. При разряде/заряде 3-4 аккумуляторов работает все время. При заряде/разряде 2 энелупов включается и выключается иногда, я бы сказал 90% времени не работает. Аккумуляторы не сильно нагреваются при любом токе который я пока пробовал.

        Charger that really helps
        Pros:
        Been using this charger for quite some while and decided to share my opinion. It's may be the most functional and easy to use charger on the market. Yes, it requires some knowledge about batteries and charging but nothing tricky. Great functionality, decent build quality, charging current range enough for almost everything. I also like nice blue display's backlight. And the main PRO - it's newer failed me yet!

        Cons:
        A little bit noisy but it's nice to have some extra overheat protection.

        Всеядное зарядное устройство BT-C3100
        Pros:
        Являясь обладателем BM100 для NiCd NiMh и неплохой, но музыкальной, зарядки Soshine для лития, хотел большего и лучшего. Я видел универсальные устройства, но без всяких вкусностей типа измерения емкости и тренировки. И тут я увидел ее...©
        Жаба была повержена за полдня. Заказ был сделан, оплачен, и на следующий же день продавец мне отправил посылку. Почта, надо сказать, не подвела

        Cons:
        На этом подведу итог, больше обозревать в данном девайсе нечего. Оно работает как должно, и работает неплохо.
        Плюсы:
        — универсальность и всеядность. это главное
        — есть возможность заряжать большим током емкие аккумуляторы
        — остальные плюсы можно выяснить в характеристиках

        This is an amazing little charger!
        Pros:
        1. Came with a US plug power adapter! Perfect
        2. Fan turns on when temperature is above 40 degree celcius
        3. LCD display shows, voltage, mah charging rate, total charging time, and accumalated mah during charge
        4. You can also revive dead batteries with the recharge function. I did this to two AA batteries I had
        4. Charges 4x18650 @ 1A each slot with no problem
        5. Charges 2x18650 @ 2A each slot, but batteries must be in charging slot 1 and 4 to do so.
        6. After exactly 1 hour of charging 4x18650 @ 1A each, the charger showed no signs of heat, the batteries were slighty warm, just barely.

        Cons:
        Fan is loud!
