Thanks for the replies!

I am aware of the voltage fluctuations. Nice to know the Opus is not too specific on input voltage. I will only connect it to the socket after engine start or after shutdown.
I had a car plugtip being fried once when running a 12volt coolbox while driving in the car on holiday. But I think it pulled more than 3amp. Could as well be due to a bad connection with high resistance and thus high temperature.

I’ll give it a shot and hopefully the fuse pops before the opus if things work out bad. In that case I guess I can place a new fuse and lower the Opus charging mAh and be fine.

So — can someone sum up?

Is the power supply currently (heh) provided with the Opus charger inadequate?

Assuming need to buy another power supply, how to identify models that are
— best (level 6) energy efficient and
— “green” (low power draw so not wasteful to leave plugged in)

The Eagle (USPS) is about to land….. Big Smile

Well, I just checked USPS Tracking and my package containing power supply from “speaker_joe” (ebay) is out for delivery to my humble abode. Thumbs Up

I place the order about noon on 19 April & it should be in my mailbox about noon today, 21 April.

That is two (2) days from California to NW Alabama!!!
Talk about fast shipping…. speaker_joe must have had it out the door headed to me a couple of minutes after I placed the order.
Wow……… Smile

I actually think this may be only the second thing I have ever bought off ebay…….. ShockedWink
But if I can find more guys like him it won’t be the last. Thumbs Up

speaker_joe on ebay gets a 10 star out of a possible 5 star rating from me.
I would highly recommend him to anyone!!!

If you were to read this……. Thank You speaker_joe!!!!! Thumbs Up

I think the power supplies have been inconsistent. Mine was inadequate, so was Teachers,,,maybe others. What was established in this thread about 2 weeks ago is that Opus chose a DIFFERENT manufacturer for the SMPS in version 2.2 . If you go back several pages you will see that.

I can not answer the efficiency/green question. I am sure Gauss163 would have an answer/info. about that!

My set up is maybe a little different. I have a strip w/ 6 outlets and a switch to turn them on/off. I do not leave ALL of them plugged in because if I did, when I hit the switch they would all come on. I plug them in as I use them.

I hope this helped a little.

One suggestion. If you get an Opus just see what happens before you buy another SMPS. Again, in this thread[~2 weeks ago] I gave a detailed acount of when mine failed and what happened. It ALWAYS happen during the CHARGE/TEST just after transition from discharge to charge.

@ teacher

Let me know how it works w/out the adapter. Mine still works fine as long as I do not move it. I am waiting a few more days for the initial adapter!

My Opus BT-C3100 V2.2 works fine during the full Charge / Test cycle with the original 220V power supply. Tested it with 4 NCR18650 3400mAh and 4 30Qs at 1000mAh charge.

Maybe It’s already written, but does this problem only occur with the V2.1’s?

Yeah hank, Wolfdawg pretty much summed that up and about the need for a new power supply. Mine definitely need one.

As far as the other two questions about green & energy efficient, I have now idea…. gausse would probably be your man for that like Wdog said.
I also do not leave mine plugged in most of the time, it is either on a strip or unplugged when not in use.

Hope this helps……… Smile

@ wolfdog ………… I can’t do that, you never answered my PM!!! (sound familiar) Big Smile
I wanted to see if you happened to know the two guys I spoke of…. Big Smile

I’ll check it out when I get home and get it out of the mailbox…… I’ll try to let you know later tonight. Thumbs Up

Yeah I got a tracking number on the adapters but it will be a few days on them at the least.

But the power supply from speaker_joe got here lightening fast!!!!
Thanks again for finding that, as well as the link to it. Smile

What is the brand name on your power supply??

No it is with the v2.2 mostly I think. That is what mine & wolfdog’s are.

Well I’m glad I brought this issue up a couple weeks ago with my unit. Looks like everything is solved now. I may get a new power supply eventually. But it doesn’t happen enough to really ve a problem at this point. Just occasionally.

Sorry for being late to this discussion… I may have missed this, but what is the brand/model number of the problematic power supply?

I have an Opus BT-C2400 (so not the 3100 discussed in this thread) that is v2.2, and came with power supply model KYT120100BV-09. Was just wondering if C3100/3400 v2.2 use the same one or different…

See post #150 and #152
  1. is My 2.2 SMPS POST #152 IS 2.1 SMPS which did not seem to have a problem. Opus CHANGED manufacturers of the SMPS which seems to be what caused the problem.

We would have to find someone who has the 3400 to determine that.

I have a 3400 —It was determined mine had the better PS—- the crazy think is I have a 3100 with the rounded corner crappy PS — when I was at the camp this week I did a charge/ test on some cells —worked perfectly

On another note—I went digging through my treasures (my wife says my junk)—I found two laptop PS —- 1 Liteon 12v 5.5a
and another IBM 14v 3.5a —-both barely heat up at all during testing

Was your charge/test for your crappy 3100 w/ 4 X 18650 3400mAh @1 amp?

Does the Lite-on look like mine?!!! Same specs!

I tested cells I had on hand —not a quad of the same battery—but 4 cells charge /test @ 1amp
The LiteOn I found looks similar to that one—-I would imagine mine is quite a bit older—I think it came from an EMachine laptop I junked several years ago

So, googling, I find there’s an Opus C3400 v3.1 version for sale out there,
https://dc-workshop.com/opencart/index.php?route=product/product&product...

and a couple of suggestions of a v3.2 (Russian language)

Has anyone found a list of the Opus charger products and specifications, to know what the different model and version numbers mean?

I wonder if they all come with the same iffy power supply.

From that “dc-workshop” review page, the spec includes

Adatper Power Supply output: 12Vdc 3.0A.

If you look at the two different models—you can see in the pictures the 3400 has a more square PS (Good One) the 3100 has a more rounded PS (Bad One)

-The 3.1 discharges to 3.1v instead of 2.8v. Here is the dealer answer to my question on Ebay:

New message from: rdana Top Rated Seller(31,011TurquoiseShooting Star)
Hi Capolini,
Yes, you are right. The discharge cut off was changed to 3.1V because most protect circuits are set at about 2.8V. So the charger could cause some cells to trip protect and the charger was getting the blame. There is no real industry standard for discharge cut off of Li-ion cells during test. 3.1V is a voltage used by many but some use 3.0V or even 2.8V. The C3400 will stay at 3.1V. I do not know what Opus will do with the C3100 V2.2. Many times they make the same change that I ask for in my chargers, but not always. Since the C3400 is manufactured only for me I will be keeping it at 3.1V. I wish that I could make the voltage selectable by the user but that may be some time off.
Thanks,
Robert

- It has already been established that the 2.1 and 2.2 versions use Different SMPS from different manufacturers. I mentioned this in an earlier post and provided info. as where to find it.

- I have no idea what SMPS the 3.1 uses.

I sent Robert[rdana] from ebay/dc workshop an email and asked him if he knows/could tell me the power supply that the 3.1 version is using.

I would be surprised if it is the same one for my 2.2v,,,,then again it is ONLY discharging to 3.1v so that itself could make a difference in power surges needed for 4 X 18650.

When I hear back from him I will post it.

Done!!!!..along w/ a beautiful bonus Picture that I took in Italy.

One of the first things I noticed was that SOLID feel to it.It is bigger than my Supernight..not by much. A 1/2” wider and a 1/4” longer.

Yours is the same as mine. The only difference is the Plug! [European/USA]

The one that Gauss posted[APD WA-36A12U] IN POST # 152 seems to be of better quality and so far no one has mentioned problems w/ it.

Here is mine again so we do not have to go to post #150 again!

The bottom line is IF it works Ok,,,fine. If not you spend $10 for a much. much better quality one[Lite-On 12v/5.5a/66w].

For those that may have missed. The first cord I got w/ my Opus got way too hot and I exchanged it for the second one which could not do the CHARGE/TEST w/ out resetting!

Noooo! Ughh

Hope it keeps goin’ strong. Never noticed anything unusual with it yet, and it gets used at least twice a week.

I’ll have a preemptive search through my old-adapter-box-of-pandorra. See what it brings to light..

I did a LOT of charge/discharge tests. the reset[failure] always happened during transition from discharge to charge when the batteries were @ 2.8v and the SMPS apparently could not handle the spike of energy it needed. This was always w/ 4 X 18650 3400mAh batteries.

Yours may be fine if you just charge batteries 2x/week. I would hope you are not putting them in @ 2.8v!!!

It doesn’t have to be 3400 batteries. When I first brought this issue up it happens around 2.8-3.4ish volts. I test lots of laptop pulls, powertool pulls most of which are 1200-2200mah left. It causes the same spikes regardless of the capacity. Its the low voltage

But I’m glad you caught it early and got a fix. At first you said your didn’t do it like mine. Mine was like that at first. It took me a a couple months to actually realize something was going on. I figured my daughter did something or etc. And doesnt always happen. I think because when testing pack pulls the batteries finish at different times. Sometimes a few mins all the way to 30+ mins apart so the spiking isn’t the same as 4 batteries all switching within 5-10 mins of each other. I have 3 sets of 4 batteries that are married together. And even after a few hundred cycles now they still finish charging or discharging within a few mins of each other. It happens more when I charge these then anything else. I first noticed it during regular charge not charge test. 95% of the time it’s happened to me has been just putting 4 batteries in at 1 amp.

My opus gets used daily at least 6-10 batteries a day. If its a park night 20-30+ batteries. I beat the hell out of some batteries. That’s what’s great about pack pulls. They are free I can beat them hard for another 6-12 months and recycle them get more free pound them down and so on and save my 30q/hg2/ga/25r life cycles for when I want to use them. Hell I’ve found 2 brand new hg2 in the recycle bin because of a torn wrapper. Still tested at original capacity. Vtc5s with decent life. Laptop packs with one shorted cell others basically brand new. And plenty of packs that’s went back in the bin. But you would be surprised at what people put out for recycling. I’ve found most tool pack batteries are in great shape. Hadn’t had a real bad one yet. 99% of the time the circuit board fries from the heat. And tool pack batteries are 20+amp natreriesm 15l/20r/25r/hg2 etc I’m using the 25amp batteries from the 40volt ryobi packs I found a few weeks back for my vaping needs. Low capacity unfortunitly 1300mah. 42 out of 60 tested at or within 100mah the other 18 were completely shorted out. Most people saw Samsung in those packs but mine are LG work great I don’t vape over 8-9 amps anyways I never unplug my chsrgers. They stay connected 24/7 So it doesn’t happen enough to bother me. Something is being charged 24/7 But enough that I noticed a pattern. I’ll probably end up ordering a cord at some point. But its not high on my to do list. I’d rather buy a c8/x6 host for $10 at this point.

Blf has changed a lot since I've been here. Lots of snow flakes and easily offended over nothing. When the forum use to be great and people joked around and could take a joke. It's a forum it's not that serious. Let's make BLF great again!

^^^^^

As I said before my failures ALWAYS happened shortly after transition from discharge to charge. That is the only time it happened.ALWAYS w/ 4 X 18650 3400mah. That could be a coincidence because most of my 4 cell torches run on 3400mah. It may have happened if I had 4 X 2600mAh batteries.

I am just glad that all of us shared this stuff and I am very happy w/ my Lite-On 12V/5.5A/66W SMPS! Thumbs Up It is superb quality compared to the one Opus gives us.

I believe it’s happening due to charging 4 cells at 1amp on the most demanding part of the charge ( 2.8 —- ) I test lots of cells—many times I buy 20 cells ( for instance 30Qs) I test them then I make matched sets—when I charge test no matter how charged the cells are—Type of cells—etc— most of the time they never go to discharge at the same exact time—then again at the end of the discharge stage they never start charging at the exact same time— hope this makes some sort of sense to someone —-LOL

That has been my experience also[ 4 X 18650 3400 @1A]. Speed4goal has had a different experience!

Al I know is my dilemma is solved and my Lite-On SMPS works dandy!
