Main Features:
● The charging current can be selected for 200mA, 300mA, 500mA, 700mA and 1000Ma (1500mA and 2000mA can only be applied when only slot 1 or 4 is selected). Default discharging current is 500mA
● It provides four independent charging slots for rechargeable batteries. The charger can charge batteries of different type and size and with different capacity at the same time
● The charger integrates the minus delta voltage (-ΔV) for NiCd or NiMh battery charging termination, and for Li-ion batteries charging to 4.2V with pre-selected constant current.(3.7 Li-FeO4 and 4.35 type high voltage batteries charging mode can be selected through switch on board)
● The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating
● 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
● Easy to read LCD with back light Showing Battery Voltage, Charge / Discharge Current, Charging Time, Battery Capacity etc.
● Designed for AA (LR6) and AAA (LR3)NiCd, NiMH or 3.7V Li-ion rechargeable batteries in size type of 10440, 14500, 16340, 18500, 18650, 26650, 26500
● Ideal for office and home use
● Operating Temperature: 0 - 40 deg.C
● Max Charging Capacity: 20000mAh
● Power Adapter: Output: DC 12V, 3.0A, Input: 100-240V, 50/60Hz

Highlight
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 are 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.
4. Better safety feature: PCB temperature was used to in controlling fan on/off only with 2.0V, now this function is enhenced so that temperature is monitored for entering thermal shutdown mode when excessive high temperautre is reached. It is especially helpful when fan is not running and which can lead to plastic melt down happening.
5. New fan cover make better protection for cooling fan.

 Opus BT-C3100 V2.1 Li-ion NiCd NiMh LCD Digital Intelligent 4-Slot Battery Charger with EU Adapter
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.

Opus BT-C3100 V2.1 Li-ion NiCd NiMh LCD Digital Intelligent 4-Slot Battery Charger with EU Adapter 

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 V2.1 Li-ion NiCd NiMh LCD Digital Intelligent 4-Slot Battery Charger with EU Adapter

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

Opus BT-C3100 V2.1 Li-ion NiCd NiMh LCD Digital Intelligent 4-Slot Battery Charger with EU Adapter

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

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.

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.

A couple of different NiMH batteries in the charger.

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

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.

Customer Questions & Answers

  • By  suprarb Aug-28/2015 05:08:25

    Question:
    If the new OPUSBT-C3100V2.2 is supposed to be the upgraded version fro the OPUS BT-C3100V1.1 WHY IS THE V1.1 RETAIL FOR DOUBLE THE PRICE ? WHAT DOES THE V2.2 DO THAT THE VERSION 2.1 DOES NOT DO WHAT IMPROVMENTS WERE SUPPOSEDLY MADE FOR THIS SO CALLED UPDATED VERSION THAT REATAILS AT FULL PRICE FOR 1/2 OF THE V2.1? COULD YOU PLEASE POINT OUT ANY ADDITIONAL FEATURES OR ASPECTS THAT OPUS APROVED UPON AND IF THEY DID WHY IS THE V1.1 STILL DOUBLE THE PRICE EVERY WHERE? ALSO DO YOU MATCH PRICES?THANK YOU FOR ANY HELP AND INFORMATIO YOU MAY BE ABLE TO PROVIDE ME WITH AS I PLAN ON ORDERING 4-5 OF THESE FOR MY VAPOR CLUB...

    Reply:
    Hi Suprarb, this item is BT - C3100 V2.1 model. The V2.2 is very similar to the V2. but the V2.2 has a screen backlight function which the V2.1 doesn't have. And the price is unified by the vendor. Now we offer some discount for V2.2 model so the price is very favorable. I am sorry that we can not give the comparison between V2.2 and V1.1 because we don't have any information about V1.1 we don't the V1.1 in stock to sell. Thank you for your kind understanding. Please feel free to ask if you have further questions.
