    NEW added quick test mode to test the battery impedance
    Four working mode available at user's choice: Charge, Discharge, Test, Quick Test and Refresh
    ● 4 independent charging slots charge rechargeable batteries of different types and sizes and with different capacities at the same time
    ● Charging current can be selected to be 200mA, 300mA, 500mA, 700mA or 1000mA ( 1500mA and 2000mA can be applied when only slot 1 or 4 is selected ). Default discharging current is 500mA
    ● Integrates the minus delta voltage ( -ΔV ) for NiCd or NiMh batteries charging termination, and for Li-ion batteries charging to 4.2V with pre-selected constant current. ( 3.7V Li-FeO4 and 4.35V high voltage batteries charging mode can be selected through switch on board )
    ● Easy-to-read LCD with back light showing battery Voltage, Charge / Discharge Current, Charging Time, Battery Capacity, etc.
    ● Includes overheat detection to protect rechargeable batteries and charger itself from overheating
    ● Designed for AA ( LR6 ) and AAA ( LR3 )NiCd, NiMH or 3.7V Li-ion rechargeable batteries in size type of 18650, 14500, 16340, 10440, also compatible with 10340, 18650, 26650, 26500 ( printed on the package ) and 17670, 18490, 17500, 17335 ( printed on the product )
    ● Operating temperature: 0 - 40 deg.C
    ● Max charging capacity: up to 20000mAh
    ● Power adapter: DC 12V, 3.0A ( output ), 100 - 240V, 50 / 60Hz ( input )
    ● Please NOTE: batteries are not included

    Highlights:
    1. Voltage update rate is 30s instead of 60s.
    2. Charging voltage is regulated to 4.7V instead of 5.0V, thus loading on power adapter when batteries are flat is less. 5.0V charging voltage has problem in regulating the correct current level due to this over loading current on power adapter, which lead to Panasonic brand Li-ion batteries showed wrong charging capacity value ( + 25 percent ). With 4.7V charging voltage, the load on power adapter is greatly reduced and thus can make all types of batteries charged properly.
    3. 4.35V charging time can be very long because charging current is regulated in entering the CV stage at 4.12V, which is same as 4.2V type. Now 4.35V charging algorithm is changed to 4.27V.
    5. Better safety feature: PCB temperature was used to in controlling fan on / off only with 2.0V, now this function is enhanced so that temperature is monitored for entering thermal shutdown mode when excessive high temperature is reached. It is especially helpful when fan is not running and which can lead to plastic melt down happening.
    6. New fan cover provides better protection for cooling fan.
    7. Charging current range: 200mA, 300mA, 500mA, 700mA, 1000mA, 1500mA, 2000mA
    8. Discharge current range:200mA, 300mA, 500mA, 700mA, 1000mA ( Li-ion batteries only )
    9. Max. charging capacity: 20000mAh
    10. Voltage deviation: < 0.03V @4.2V
    11. Current deviation: < 5pct

     Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries

    This charger is an analyzing charger for LiIon and NiMH batteries, which means the charger can charge and discharge while measuring.

    Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries 

    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.

    Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries

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

    Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries

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

    Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries

    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.


     Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries 

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

    Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries

    A couple of different NiMH batteries in the charger.

    And some LiIon batteries.

    Using only slot 1 and 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: 200mA, 300mA, 500mA, 700mA, 1000mA, 1500mA, 2000mA

    Discharge currents: 200mA, 300mA, 500mA, 700mA, 1000mA

    The charger can easily handle 
    70mm 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 Li-ion chemistries.

        Good charger
        Pros:
        This charger meets all my needs:
        It has a single channel charge, that is, you can upload an unlimited number of batteries, so that only one, two, three or all four simultaneously. This is important for me because I have a number of devices that only need a battery or three.
        Ordinary charger can only pairs (ie 2 or 4 at a time) load.
        You can combine the types of batteries colored, so you can simultaneously charge different capacity NiMH batteries and lithium ion batteries.
        Each span can individually adjust the charging current and the function.
        Functions dominates the charger following:
        * Download (Sure)
        * Exhaust (in order to avoid any memory effects with NiMH)
        * Refresh (charger repeatedly discharge and charge cycles until improvement in battery capacity you get more. So you can old batteries, or those who have long remained, still breathing a little 'life)
        However, Opus can also deal with Li-Ion batteries, and I have the chance to request a particular device in your home. Moreover, the battery of tests (measurement of internal resistance).
        I hardly use this feature however.
        A fan, the device is also to cool the batteries, which should become warm during charging. I was able to observe that the fans have already activated, very hot but the batteries were not.
        Conclusion: excellent charger handyman.
        Cons:
        No

        BT-C3100 V2.2, An Excellent Charger
        Pros:
        Backlit screen (will turn it off after 20 seconds)
        Backlit can be turned on permanently by pressing "DISPLAY" for 3 seconds.
        Charges Ni-Cd, NiMH and Li-ion batteries.
        Rubber feet.
        Approx. 3/16" bottom clearance
        6 internal temperature sensors.
        Small fan to exhaust heat.
        Fan noise has been improved from previous version (BT-C3100 V2.1).
        Excellent build quality.

        Has 5 MODES:
        CHARGE, DISCHARGE, REFRESH (DISCHARGE REFRESH),
        TEST (CHARGE TEST), QUICK TEST.

        CHARGE:
        Charges battery to maximum capacity.

        DISCHARGE:
        Discharges battery. Reduces the memory effect in the battery.

        REFRESH (DISCHARGE REFRESH):
        Discharges, then charges battery 3 complete cycles to optimize it's
        maximum capacity.

        TEST (CHARGE TEST):
        Checks the capacity of the battery.

        QUICK TEST:
        The charger checks the dynamic internal battery resistance.
        Consult manual for further details.

        This is an excellent, fun, easy to use, charger, that gives you total control of how
        you want to charge and maintain your batteries. A big plus is the ability to get the
        capacity of the batteries. The fan noise is considerably less annoying than the one
        on the V2.1 charger, IMHO. This charger is a great companion to my XTAR VP2.

        GearBest got it to me, fast!!!
        Thanks!!

        Great charger
        Pros:
        All automatic, will take many different sizes of battery. Can be set to different custom charging. But for the most part I will run this on automatic. I like the refresh function for use on older batteries.

        Versatile battery charger
        Pros:
        1. Build quality is great.
        2. Operational panel is very clear and easy to understand.
        3. Can charge up to 2A (for a single battery).
        4. The fan does help cooling down temperature (but it will still be warm to hot if you charge it at high current).
        Cons:
        The biggest and annoying issue I found is that, sometimes the fan may behave weirdly. It will make irregular and loud noise when it's running, which makes me wonder if there is any issue about the upgrade from V2.1 to V2.2.

        Good charger
        Pros:
        This charger meets all my needs:
        It has a single channel charge, that is, you can upload an unlimited number of batteries, so that only one, two, three or all four simultaneously. This is important for me because I have a number of devices that only need a battery or three.
        Ordinary charger can only pairs (ie 2 or 4 at a time) load.
        You can combine the types of batteries colored, so you can simultaneously charge different capacity NiMH batteries and lithium ion batteries.
        Each span can individually adjust the charging current and the function.
        Functions dominates the charger following:
        * Download (Sure)
        * Exhaust (in order to avoid any memory effects with NiMH)
        * Refresh (charger repeatedly discharge and charge cycles until improvement in battery capacity you get more. So you can old batteries, or those who have long remained, still breathing a little 'life)
        However, Opus can also deal with Li-Ion batteries, and I have the chance to request a particular device in your home. Moreover, the battery of tests (measurement of internal resistance).
        I hardly use this feature however.
        A fan, the device is also to cool the batteries, which should become warm during charging. I was able to observe that the fans have already activated, very hot but the batteries were not.
        Conclusion: excellent charger handyman.

        Cons:
