    My BT-3400 v. 2.2 came with a bum wall wart. It would shut down charging 4 cells at 1A, but worked perfectly charging them up at 700mA.

    Robert at first sent me a 2A replacement wart and then a 3A wart and I haven't had a problem outside of that first week.

    He grabbed a used one he had on his bench, because I wanted him to test it out before sending and I just didn't care.

    Let me look, I have all three here!

    First one 3A: No name: KYT120300BV, kind of has a rounded, contoured case with with embossed lines on the back.

    Second 2A: No name: KYT120200BU, same contoured case with lines.

    Third 3A: APD: Asian Power Devices: WA-3612U.

    I'll tell you what, I now have some spare wall warts for my Xtar chargers!

    The third was the charm, right? APD = Asian Power Devices is likely much better quality than the KYT = Shenzen KeyingTong Electronic Tech. The APD is what Opus originally supplied. Looks like they switched to a cheaper SMPS in later versions. See here for labels and more.

    I don't know much about the manufacturers, but over the years, I've had them crap out on me, most recently a dinky 7-25vdc for a Dirt Devil hand vac, so I realize that they're cheap and probably don't have 50 cents worth of materials in them.

    The OEM Opus dud still works well at 700mAx4, so it can be used with other devices.

    its so much more flexible than anything out there right now
    beauty is you can set your cut off voltage to what ever you want
    ive got mine set at 4,23, and they will rest at 4.21 after an hour or so of coming off
    you can charge up to 3 amps , for ALL 4 CHANNELS if you need to, not just 1 amp
    youll find out how much fun battery charging can be if you get it

    I got a opus v2.2 a few days ago , when charging I set the ma current at 500 for AAA'S & 700 for AA'S , it charges fine & the ma current is what it's supposed to be but when the battery's get close to being full I noticed the current drop to about 250-300ish for the AAA'S & about 400ish for the AA'S ,is this normal behaviour ?
    I first noticed this with some older AAA led lenser battery's ( the manual says its normal for old high internal resistance batteries) but I've noticed it does it on new eneloops , I was worried that because the ma current gets close to 200ma that it might not terminate but it does terminate fine.
    Is this current drop towards the the last stages of charging acceptable behaviour ?

    That is normal and it is suppose to do that for all battery types. The last phase can take the longest on some chargers and this is when the current is reduced.


    • Can be set to 3.7V LiFeO4 charging or 4.35V high voltage li-ion charging by a switch on the PCB. Default li-ion charging mode is 4.2V CC/CV.

    Are you sure it is V2.2? Iirc, HKJs reviews showed that versions prior to 2.0 used a CC/CV-type algorithm for NiMh, which reduces the current at the end. But starting at V2.0 they switched to a dV/dt algorithm.

    I ordered the 2.2 & the box says 2.2 also the screen on startup says 2.2 ,
    I think it's probly a 2.2.

    For those interested. My Opus and others have had problems w/ the power supply. Basically the SMPS that came w/ the opus can not handle spikes in the current[~6a] when the batteries are at a low voltage. This happens shortly after transition from discharge to charge where the batteries are ~ 2.8 to 3.0v.The charger resets itself[basically a quick on/off] and ALL the data for Capacity is gone,,~3 hours wasted!

    Me and a few others got a good power supply w/ a great reputation. All the info you need is on BLF.

    Here is the thread:The exciting action, HKJ included, and ALL the drama and solutions start @ post#124

    http://budgetlightforum.com/node/34663?page=4

    Here is my new power supply: A quick note about it. Courtesy Dr. Gauss

    Lite-On are a power supply OEM used by most major computer manufacturers, e.g. if your search on “LITEON oem” on eBay you will see power supplies they made for Acer, Apple, Cisco, Dell, Gateway, HP, IBM, Kodak, Lenovo, Samsung, Sony, Toshiba, etc. That should help convince you of their reputation as a top-tier SMPS manufacturer.

    LITEON is good stuff. I've built or updated dozens of PCs with that brand PSU over the years. Optical drives, too. Might even be overkill here, but since when has that been a bad thing?

    I do not think it is overkill. The Liteon I have is 12V/5.5A/66W. The Opus gives us is 12V/3A/36W.

    I trust HKJ's Knowledge. Here are some of his excerpts on BLF:

    The most likely cause is the power supply. The Opus will draw more than 3A in peak current, in my test I measured 6A for nearly 0.02 second. Then 0A for 0.03 seconds, bringing the average below 3A

    ************************************************** ************************************************** *************
    Here it may not be a question about a cheap power supply.
    The charger needs a 3A supply that can deliver maybe 6A peak.
    A charger that can deliver 3A and shuts down at 4A is a perfectly fine supply, but would not work with this charger and empty batteries.
    ************************************************** ************************************************** **************
    Liteon is a good brand and as long as the power supply is rated at 5A or more I doubt you will get any problems with the current pulses.
    The problem is finding a 3A power supply that will supply 6A for a short time and in my opinion that is the responsibility of the manufacturer ( i.e. Opus). Using a 5A or more supply will work as long as the supply has a honest rating.
    ************************************************** ************************************************** **************


    Hi
    It is a very good idea to get a better power supply with the charger.
    As I found out while I initially tested the charger: The peaks are worst with an empty cell, especially newer cells with lower empty voltage.
    Opus did reduce the peak enough to work with the power supply they used at that time.

    Best regards

    It might seem a bit overkill at first glance, but the reason that I recommended on BLF the eBay $10 12V/66W LITEON PA-1660-2SA1 is that it was the best deal that I could find on a new top-tier power supply capable of handling the large current pulses demanded by the Opus BT-C3100 when charging 4 cells at 1A (see e.g. HKJ's reviews for graphs). At $10 shipped, it is a great bargain for a new top-tier power supply built on the latest technology (e.g. efficiency level VI). It will run very cool powering the Opus, so it will have a very long life. Further, it will likely prolong the life of the Opus compared to using the supplied overloaded lower-quality SMPS.

    As you can see from the 2nd eBay link, the LITEONs have been selling quickly, but the eBay seller still has a handful left, so get 'em while they last. Follow the first BLF link for a long thread with much further discussion on this topic.

    Note: LITEON is a top-tier power supply manufacturer employed by many top-tier PC manufacturers, e.g. if you search on "LITEON oem” on eBay you will see power supplies they made for Acer, Apple, Cisco, Dell, Gateway, HP, IBM, Kodak, Lenovo, Samsung, Sony, Toshiba, etc, which should help convince you of their reputation. LITEON (and Delta) are the OEMs for the Apple magsafe power supplies. A top-quality 12V/66W SMPS has many applications for anyone who tinkers with electronics, so it is a good investment.

    PS To clarify HKJ's remark that "Opus did reduce the peak enough to work with the power supply they used at that time", it is helpful to add some context from the BLF thread. As I mentioned there, Opus appears to have switched their 12V/3A power supplies from an Asian Power Devices APD WA-36A12U to a KYT120300BV by Shenzen KeyingTong Electronic Tech. Based on reports on BLF, it appears that only the latest KYT supply is hiccuping (rebooting) when the Opus is at full load (though this is probably also greatly stressing the APD too). So if you plan to use the Opus at full load then I highly recommed to upgrade the power supply. This is essential if you have an early Opus version (where the peaks were even larger - up to 12A. - which greatly distorted the calculation of mAh charged).

    UPDATE:

    My last post is ironic! On May 18th I had a fatal mishap with Opus #2 who I named "King Opus" because of its ability to be more accurate than my original Opus.A fine gentleman named speaker_joe[Ebay dealer] donated Three[3] top tier Delta fans to me. The plugs were different so I attempted my FIRST ever splice. All was well for several hours and then King Opus got fried.

    The next day I got #3 Opus who I named "Prince Opus".
    The Top Tier Lite-On SMPS was doing its job as expected. No more RESET shortly after discharge cycle was complete.

    The Prince
    acquired this name after My other Two Delta fans were professionally spliced by DB custom[Dale] who is a member here and on BLF. The problem w/ the Prince was there were way too many STOPPAGES during the discharge cycle.The STOPPAGES are listed in the manual. However, through my testing it showed that my DELTA top tier fan ELIMINATED this, maybe in combination with other factors[?],,,,internal variances from charger to charger.As a result of that my capacity readings were more accurate and closer to specs. KING OPUS NEVER had a stoppage during the discharge phase.


    So many people helped me along the way. HKJ.speaker_joe, Dale, "rdana" who sells the 3400 V3.1 Opus and several other members whose input helped me and in turn prompted me to contact HENRY XU of Opus who I have exchanged about 2 dozen emails with. Henry appreciated my efforts and when the NEW OPUS comes out in several months he is giving me One of those to me.

    The next post will have photos with explanations.

    Stock fan: 5V/0.13A/0.65W It has a resistor on it to regulate the current




    Top Tier DELTA fan: 12V/0.12A/1.44W



    Plug size difference-Opus stock[ADDA] on Left and DELTA on right.



    Comparison in DEPTH. L X W is the same[25mm] Opus in forefront. ADDA=25mm X 25mm X 09mm------DELTA =25mm X 25mm X 10.5mm



    1AMH-The transistor behind the fan that helped HKJ determine that the Delta did not have too much Wattage. Delta 1.44W, 1AMH has ability to take slighly over 2W.





    Dales excellent splice job.



    Best view to show installed DELTA fan. It is obviously not made for this. It does not have grooves that original fan has and is 1.5mm thicker[depth]. Looks great to me and works like a charm. The difference is like a hair dryer on Low[ADDA] and one on medium[DELTA]! It is really not much louder.



    DELTA specs.
    Specification

    • Nominal voltage : 12 V
    • Current : 0.12 A
    • Operating voltage range : 4 - 12 V
    • Fan speed : 13,000 RPM
    • Performance : 2.4 CFM
    • Noise : 28 dBa
    • Size : 25 x 25 x 10 mm without heatsink

    Here is a photo of the entire ADDA fan on Left w/ the resistor.

    The fan on the right is supposedly the replacement fan that a few BLF members found in their charger,,,the same exact pieces of Junk I bought from Gear best! That label for that will be in the second photo.



    This 9 blade[more resistance] fan was so quiet and its ability to move air[CFM] was FEEBLE!
