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

HKJ—You are true one of a kind—-your countless reviews and post have helped so many people—I enjoy reading your reviews—very informative to every one———————-Thanks

teacher—I didn’t forget you—great way to sum it all up—are you the guy around the camp fire that keeps the two drunk friends from fighting—LOL

Thank you chops, I appreciate that. :+1: . But hey, even a blind hog finds an acorn now and then. :smiley:

Hmmmmm, that would depend on who the “two friends were”. :wink:

This is totally irrelevant ———-

gauss…. :person_facepalming: … I’m not raggin’ on you my friend. But this is what I am talking about…. I even “tried” to look it up. :slight_smile: . No joy…
Given, I am not the sharpest knife in the drawer… but this sounds like it came straight from a Jargon Generator … :weary:

Meta-level tangents = 元級切線 ……. both of these mean about the same thing to me.

Your gonna have to try and “dumb it down” a bit more or at least provide a link so I can find out what you mean when you write something like this…. please. :slight_smile:

Maybe that is how I learned how to use forums…. but at this rate I’ll never know for sure. :wink:

Oh, my bad. :person_facepalming: … But thanks for letting us know. :+1: … :wink:

I just completed a trivial test with 3 chargers—- 3100 / 3400 / Liitokala 500
With a 3 cell group of NOS laptop pulls that were charged and matched a year ago on the 3400 ( didn’t want to abuse good cells)
My conclusion—the BT-3100 mah reading is around 5-6 percent higher than the other 2 chargers—The 3400 and the 500 test fairly close on average—amazing considering the Opus’ discharge @ 1 amp and the Lii 500 @ .5 amp—— When you compare the readings as a group,then figure their percentage match—all 3 chargers are very close in that regard—- this set of cells with all 3 chargers is around 4% match— Not sure why there is #1 cell that is a flyer ( target term) but the overall average is pretty consistent

BT-3100 / Lii 500 / BT3400

cell #1 2122 / 2161 / 1999

cell #2 2208 / 2070 / 2070

cell #3 2166 / 2077 / 2083

Thanks for the info & pics of thr LiteOn gauss!! Much appreciated…. :slight_smile:

So can anyone sum up what the differences are between the C3400 & C3100 v2.1?

The 3400 discharge to 3.1v ,3100 discharge to 2.8.

It would depend on when you bought the 3400…….

Haven’t bought one yet. My C3100 v1 is on its last leg, so I’m looking to get another…. or “upgrade” to the SkyRC MC3000

If you upgrade to the MC-3000 just be aware of what you are getting to. I only thought I knew when I got one…. :person_facepalming:

A great charger no doubt. :+1: Much to complicated for me though. :slight_smile:

I love the UI of the Opus, but I feel like it’s worth the price point. I constantly get ghost battery indications (screen reads FULL after I take the battery out), bad voltage readings (full battery reads 0.2v), the fan has been giving me trouble for 2 years and just died, and one of the negative terminals snapped off so I’m left with 3 slots.

So I’ve heard that the newer Opus chargers have fixed these issues, but it makes me wonder if I should just invest in a higher priced charger

I don’t know if all the issues have been “fixed” or not on the OPUS. We discussed a bunch in this thread & a couple of others too.
My 3100 v2.2 works fine & I have no issues at all now that I upgraded the power supply.
Never had any issues at all with the Lii 500… it is my favorite.

Good luck choosing.

I know this is an old old thread but I bought the 3400 ,and when I asked the seller from e-bay (rdna)told the difference was the “sofrtware”
That’s all he knew or told me I have had it a little over a year and the only issue I have had is the power source melted and the seller is sending me a new one under warranty

That LITEON is sold out, and my Opus V2.2 came with the KYT 12V 3A power supply.

Is there another power supply you can recommend for this charger? Will any old 12V >=4A power supply work better than the supplied supply, or are there characteristics I should be looking for, like that efficiency standard?
