Difference between Opus BT-C3400 & BT-C3100 v2.1?

wolfdog1226 · 2017-04-07T21:26:51.000Z

Let me look,not sure if I can decipher while it is charging!

I looked on line for these and they were $15 and up,I do not want to pay half the cost of my charger for a power supply! I am not confident If I ordered one online that it would be the right one,when I can just get another opus,probably w./ the same issue!!

My bad, don’t worry about it if you can’t. I’ll just try tomorrow when I find out the plug size.

There is no indication of the size of the barrel plug in the manual or written on the charger/plug itself. It will take 10 or 15 minutes to post pictures,that will give info gausse wants but may not help for barrel plug size.

The C3100 uses the most common 5.5 x 2.1mm DC barrel connector.

Thanks gauss163. :+1: I appreciate that info.

Already got the size from gauss, so the only thing left is the power supply spec pic for gauss. :+1:

$21.13,crazy,more than half of what I paid for the opus!

This OPUS thread is bringing the love back,no more bickering!

OK,Thanks,I will check that out.

I did find some on Ebay for $7,seems awfully cheap………I wonder what the quality will be?

I’ve tried to make my 3400 produce the problem—it won’t do it—charging (4) 30Qs at 1amp without a hitch—-my 3100 is at my camp—I have also tried my power supply from my hobby charger 12v/ 5a —-works perfectly—these are readily available on ebay— also I’m curious if anyone has a car adapter—try it in your car on straight 12v

I just retested my 3400 with my 2a power supply—-it reset almost the instant it started charging—I’m pretty confident it’s a power supply issue—if I remember correctly the 3100 has a more rounded edge PS—where as the 3400 I have it’s square—most likely updated

Thanks,according to Gausse the one you posted has the Wrong barrel connector size.

Connecter size: 5.5mm/2.5mm

It should be 5.5mm/2.1mm??
One of you are wrong,I just ordered the 2.1mm,I hope it is the CORRECT one!!!

P.S. Mine never failed while charging 4 x 18650 @1 amp,only when I did the charge /test

chops728 · 2017-04-07T23:21:15.000Z

Not sure what size barrel I have— it’s plastic insert is yellow—thought it might be color coded

Were you doing it like outlined below chops???

wolfdog1226:

Did a Discharge/Test @ 1amp. I came in the room right after the 4 X 18650 Orbtronic were discharged and just went into CHARGE cycle. I noticed it was charging 500mAh and the Capacity data was NOT there. I set it back to 1000mAh. Came back in room 5 minutes later and it was 500mAh again! Set it back to 1000mah and this time I watched it. Three[3] times in a row the unit reset[shut off] and defaulted to 500mah again!

wolfdog1226:

The discharge process was over and it was transitioning to charge. that is when it kept turning off and defaulting to 500mAh.

wolfdog1226 · 2017-04-07T23:32:52.000Z

That may be it,the APD is better. That is probably the problem.

teacher · 2017-04-07T23:34:38.000Z

Sorry, I may be a bit behind. I am on my phone now…… :person_facepalming:

It is a slow go to say the least……

RobertB · 2017-04-08T01:04:03.000Z

I charge 4 cells at a time @ 1A often, and never had that reset happen. My power supply is plugged into a Tripp lite Isobar with line filters though. Wonder if that has anything to do with it.

Version 2.2, KYT power supply

chops728 · 2017-04-07T23:35:22.000Z

gauss163:

His 2.5 also works because its 2.5 inner hole is bigger than the 2.1 mating inner pin, so it will fit, but may be a bit loose (some have springs that make them work for 2.5 or 2.1 pins).

As for the quality, who knows. It’s probably no worse than the KYT that you currently have. And since it has a lot of headroom (60W vs 36W) it won’t be stressed much.

from my calculations using all my fingers and most of my toes—roughly a shade more than a 64th bigger

Does yours have the KYT or APD power supply (see pics above), and what version do you have? (shown briefly at power-on)

Opus 3400/2.1 APD power supply

wolfdog1226 · 2017-04-08T02:08:14.000Z

OK,The latest!

I decided to do another Charge/Test to see if it would replicate the failure from earlier today. For those not familiar, that test is CHARGE/DISCHARGE and CHARGE to get capacity results. Earlier today it failed several times when it was transitioning from the discharge phase to the charge phase. Basically reset[turned off/on again] and defaults to 500mAh instead of the 1000mah I used for the test[4 x 18650]

So,before my hike I checked the batteries and AFTER the charge[first phase] was complete,it did NOT transition to the discharge phase! I am positive I had the setting for CHARGE/TEST. The read out had charge instead of charge/test!!I have no clue as to why?!

How does that happen? Is that related to the Power supply that seems to be the consensus of the first mishap?

My amateur guess is in addition or possibly just by itself, there is an electrical component failing internally?

I do know this. I do not have the patience that a lot of you guys have.

Opus #1- I returned it because I felt it did not charge high enough[4.15v] and the discharge tests were too high!! Let it also be known that I did return the Power supply first because it got way too hot,the charger followed in a few days. That was the first indication of a power supply problem!

Opus #2[the one I have now] charges 0.03v higher and much more accurate capacity tests.
Unfortunately it has the issues that have been discussed today.I am disappointed because I was happy w/ end voltage and capacity results.

Opus #3- I can return Opus #2 and get #3. Almost certain that is what I am going to do. If that one starts to have the same issues I can use the 12v/5a power supply that I just ordered!

I am NOT convinced that the power supply is the only thing wrong with my charger.

The only way I would delay getting Opus #3 is if Jon Caserta[owner Liionwholesale] would agree to let me keep this another 10 days or so until the power supply comes and I have several days to do tests. I think he would do that.

In any event,if there is an Opus Three and it fails or this one fails after new power supply,I am finished w/ Mr. Opus and Mr. Efest LUC V4 will come out of storage and be with my 2 X FENIX-ARE and KP-L2 in my flashlight laboratory!

,those are my amateur, gut feeling thoughts mixed in w/ facts!

wolfdog1226 · 2017-04-08T03:34:48.000Z

ok,this time I was there when it transitioned from FULL Discharge to begin charging stage.

Two minutes after discharge was complete and Charging began, it did the same thing as before. It shut off/reset and came back on default charging of 500mAh :person_facepalming:

EDIT: Right before it happened[just like last time] you could hear the fan weaken like it and the unit was losing power, then it shut off/reset and came back on.
