Darn, I should have known better than to even askā¦. :person_facepalming: Try to pay you a compliment about your original emai to H Xu & you canāt handle it.
Actually, after telling you your email looked just fine & that you seemed to have covered everything wellā¦ā¦ Most of what āIā said was agreeing with or expounding upon what Speed4goal had said.
With the exception of course being the part about having to spend money to fix it.
You know what fellasāthis charger isnāt worth all this āitās just a charger is allāit has limits/flaws like everything else we purchaseāwe all know how this stuff is manufactured ā CHEAPā- somethings can be fixedāsome canāt
So ā¦ so ā¦ instead of improving the power supply, theyāre trying to eliminate the current draw pulse that overwhelms the power supply.
Maybe.
And in the meanwhile, theyāve told the power supply builder to quit using chewing gum in place of good capacitors, or something?
(since itās the identical model, identical spec, but the label changed āplus 17 on the cornerā)
I can see a meme possible here for reviewers:
āWe found this to be a mediocre product, the manufacturer should put 17 on the corner to improve it ā¦. ā
You have a point there,However, I am going to continue to exchange emails with him and get answers until āMY PEOPLEā get the kickbacks necessary to reimburse ALL of us 100 fold! :+1: :sunglasses: :smiling_imp:
The power supply has its internal design changed completely. we have minimum over current protection from previous 6A to 7A, and its output power capability is also higher.
we are making more testing to confirm this.
What kind of power you are expecting us to use? can you make any suggestion? you mean with 12v 5A rate power supply?

Hi Henry,
Why didnāt you provide that information[specs] in the first email? If your promoting a new design it would be nice to provide pertinent information instead of being vague!
In regards to the power supply.
-The one provided for my charger[KYT120300BV] was inadequate and failed as described in my initial email.
- The one I bought myself is very high quality[LITE-ON 12V/5.5A/66W]
-Your NEW design is yet to be used and proven sufficient.
To further answer your question: Whether it is 3a/4a/5a ect. It NEEDS to the job. That is your companies responsibility.
I hope it works well for the people who buy the charger. For me and a few others it is irrelevant because we have already used our own money for replacements.
None of us are buying these things to have to figure out what is wrong with them and then patch them up.
So what are the specs of this new fan that will be an additional $5 and who is the manufacturer?
I hope your not mad at me for borrowing the quote. āNone of us are buying these things to have to figure out what is wrong with them and then patch them upā.
It was a perfect quote to use in my rebuttal!
I have been writing poems and quotes for a long time. I enjoy philosophical, meaningful, simple and direct communication,especially when it is written.
I will share this with you. I wrote this yesterday morning before the suicide bomber in Manchester UK struck.
To me it is eerie, to others it may be a coincidence.
āIf people could be more like Dogs the world would be a better place.There would be much LESS conflict and violence, instead there would be true harmony and grace.ā
Well said wolfdog!!! :+1: I agree also, that was the āperfect quote to use in your rebuttal!ā
I also have a suspicion that hank is in no way āmadā that you used it. He is a team player as most all of us are. :+1: Personally, I am estatic you found the quote, taken from post #678; so useful in your rebuttal. It definitely had a ring of honesty & truth to it!!! :+1:
Oh yeah, Iām not mad that you used it eitherā¦ā¦ I am, as previously stated; most pleased you found it useful.
.
I think it is time to pass the torch. Why donāt you take over now?
Then again, there is really nothing left for him to tell us! Whoever buys the new Opus package can report its successes or failures.
I have done a lot of thinking the last hour. It is time for me to focus on finding a job instead of spending valuable time trying to get answers for something[Opus Charger] that at this point is irrelevant to me. There is no need for me to get frustrated anymore.
Hmmmmmn, well said gauss. :+1: Kinda nailed me right between the eyes, :person_facepalming:
I have been somewhat critical of Mr Xu. And basically, he has forgotten more than I know.
Mr. Xu, should by some miracle you read this; my apologies for any criticism I aimed in your direction. You have been responsive to Mr. Robertās emails and that at least says you are listening. Thank you!!! :+1: ā¦ And thank you for providing the information you have thus far.
~
@ gaussā¦.
I do understand what you are saying about the labels gauss, but IMOā¦ Considering all that has gone on about the power supply, it would have been nice had the information been received in the first response to Robert (wolfdog). Though I do realized, due to the things you mentioned such as language barrier, etc., etc.; That is something that certainly cannot be expected. For example, if I had to correspond with him and answer questions in Chineseā¦ā¦ we would all be in a world of hurt.
Awww, come on Robert, donāt throw in the towel completely; just choose your battles.
You have found out a ton of information and in finding the āgood informationā you have dispelled about 2 tons of what turned out to be āwrong infoā.
Yeah, I understand about the time involved. I have put a lot of hours reading, researching, and mostly trying to keep up with this. BUTā¦. I have only a small fraction of the hours in it that you do. You have spearheaded this.
So yeah, do what you have to do about finding work. ; but donāt give up on this. You, and to a much lesser degree āweā almost have this whipped. And now it is basically just the principle of the thing to see it through.
And besides finding out all this info, you have somewhat brought us together as āFamilyā. :+1:
I mean look, ; you and gauss are actually talking & communicating without actually biting each others heads off most of the time. That in itself is a tremendous accomplishment!!! :+1:
We have rallied around a cause here on BLFā¦. āThe Friendly Forumā and by durn we have almost become friendly.
You have āalmost learnedā when and where to use !!! marks. Almost being the ākeyā word there, but you are doing so much betterā¦ā¦
Even though you have become āfrustratedā at times with the situation & others and possibly said a couple of things in hasteā¦ā¦ you have always so far bounced back with renewed vigor & pressed on.
You still have a bit to go to know when I am āpulling your chaināā¦ ā¦ but youāll get there.
All this is said in a somewhat comical manner, BUT I am serious about it all Robert.
Do what you have to do, relax & donāt get frustrated over this. ; but see it through as your time allows.
No problem at all hank. As it was, it gave Robert a the perfect chance to give me a compliment on something I wrote.
This whole thread has been something else to watch unfold.
But at least it seems like they play to release a 2.3 version. As long as it discharges down to 2.8 to keep it fairly accurate and it all works Iād get another. And one day in the future plan to even if its the one now. For the most part mine worked 85% of the time as intended. And for $30 investment has given me my moneys worth in a charger. Even though mine charges a little low its the only charger I have that charges to the exact voltage on all 4 slots. Someone mentioned a fix but Iām not comfortable soldering on the board. As $30 for another charger isnāt in the budget right now. Its close enough for me.
In the end it seems like something good will come out of it. It seems like they listened and will make a new revision eventually and phase this one out. Like the 2.0, and 2.1 versions.
I guess time will tell what they do Speed4goal. I agree with you pretty much. Keep the discharge to 2.8V, address the power supply issue fully, do whatever they can with the heat issue, and it would be nice if cell all came off the charger at right at 4.2V.
We will seeā¦ā¦ā¦ā¦ā¦
I decided to cut the raised vent slats out of the bottom of my 3100āThe way the vent slats are made I was only able to cut out every other one(this way left more to support the remaining onesāI feel this is a big improvement in air circulationā The air coming out the fan is 2-3 times more evident(hope that word makes sense) Iām discharge/charge testing right nowāif some one wants a pic let me know
Today I also tore apart a broke laptop for the blower/fanā thought it would be perfect for the underside of the caseāworked spectacular on a 4.2 cellā it jumped once with 12v Dead nowāit was 5V but on many post it was stated 5V will run on 12V just diminishes the lifeāI didnāt think it would be so quickāLOL
Hereās my 3100 Back with every other slat removedāI used a cut off wheel with a dremel ā- air circulation with positive end of the charger raised is 2-3 times better
Do you need BT-C3100 or our newly planed next generation charger?
we are thinking to make a design change. Our current BT-C3100 is a CV charger with simulated CC design. This design has high power adapter quality requirement.
We are making a new design so that we adopt CC charger and it will have less stress on power supply.
This new design is under R&D stage, but it will take us several months time to complete.
