Opus BT C3100 Erratic Behavior - Fan Gone???

wolfdog1226 · 2019-03-21T14:18:37.000Z

JakeDjanitor:

I hope you never accidentally put a battery in backwards. I did that one time and it was a huge mistake it destroyed my entire charger. I then redid it on video and sure enough there’s no reverse polarity protection and it fried.
If I remember correctly on power up the fan self-test maybe twice and then goes off it will only kick back on if charger is warm enough inside

I certainly would Not recommend putting them in backwards.

However, I have the BT-C3100 2.2 Version. On a few occassions I put them in backwards and Nothing happened,no damage/no explosion!

JakeDjanitor · 2019-03-21T15:26:12.000Z

That’s what I had?!! Mine literally sizzled and smoked inside.
I loved that charger, until it died.

Here is video, this is after I accidentally put in a cell backwards, and ruined bay 1

I wanted to confirm what happened on bay two

PERFECT user name for your fan,A FLUKE!!! LOL! And I am not talking about the DMM By Fluke!

Quieter.Yes. More powerful? Not a chance! The reason it is quieter is because of its inability to MOVE air as well[CFM]. The specs and difference in performance have proved it.

The reason mine is a little louder is because it has a much, much better ability to MOVE air[CFM] which keeps the charger cooler and operating better.

There is NO comparison b/w the fan you listed which is similar to the STOCK fan and my TOP TIER DELTA fan that I have been using for almost 2 years.

No more stoppages during discharge tests which gave inaccurate capacity readings and no more RESETS at the transition from discharge to charge. Believe me, read my thread, I did extensive testing to come to these conclusions!

Specs. for fans: DELTA: 25mm X 25mm X 10mm——————-ADDA:25mm X 25mm X 09mm. The only difference is 1mm in depth.

Stock[ADDA] fan- 5v/0.13a/0.65W,In terms of specs, basically the same fan as you posted.

Delta fan- 12V/0.12A/1.44W,MORE than Double the Watts to power the fan!

SPECS for delta fan. CFM [Air Volume] is the key,IT is superior to the stock fan and the replacement fan you posted. iirc their CFM is about half!

There are several factors. My DELTA FANS HAVE 5 blades,the stock fan and yours have 7 or 8 blades,quieter,and again,does not move air as well.

My fans,more expensive but well worth it. I got mine for FREE[2] from a dealer in California who was following my thread and wanted me to test his.This is another source.

I stand corrected.

wolfdog1226 · 2019-03-21T19:01:39.000Z

Thanks for being honest.

I did not know any of this until my Opus gave me problems 2 years. Dr. Gauss and others helped me understand it and suggested the DELTA replacement fan and the LITE-ON Power supply. Between the Two it is like a brand new charger.

fluke · 2019-03-21T19:04:57.000Z

I got one of the gearbest ones, my Opus runs better and a lot quieter.

But I will get one of those you listed but shipping to UK is a ransom.

If it works well and you are not having problems with your STOCK power supply, you probably do not need to.

In this thread,a very comprehensive one, you will see how I and others had multiple problems with the STOCK power supply.

The meat of the discussion starts around page #4 post #120

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

This may have been missed but what is the difference between these two chargers? It is noticed that the BT-C3400 is not available until 6 OCT 2014. It is found both on ebay and Amazon. Thank you for any thoughts on the matter.

wolfdog1226 · 2019-03-21T20:25:11.000Z

A look with my DELTA fan installed. It is slightly bigger[1mm] in Depth so it protrudes a bit.No issues, been working like a mule for 2 years!

Set up w/ my Lite-On SMPS

CLOSE UP

ChrisGarrett · 2019-03-21T22:09:31.000Z

I’ve got a BT3400 v. 2.2 and its OEM fan has been quiet, but I bought two of the Delta fans off of Ebay just to have as spares, as Wolf has suggested.

I also bought the LiteOn 5.5A 12v power brick and while I don’t use it regularly, it was fairly cheap to get ($12 shipped?) My inner hole on the barrel connector is slightly over sized, so if I jiggle it when the charger is running, it’ll disconnect, but I just don’t move the charger once things are charging.

The barrel connectors are slightly different. I got adapters for a few dollars and they are snug.

I like the 90 degree one. That is the one I have been using since spring of 2017 when I made fan/SMPS changes. :+1:

I am not sure where the link for the “angled ones are”. Your resourceful! If you google the numbers you could find the “angled ones.

Thanks Wolf. I’ll take a look, but it’s more of a minor nit. My 2A wall wart works fine, although my first one from Rdana crapped out on me @ 4x1000mA. charging.

I’m still using my original fan ,it got noisy once and I just gave the housing next to the fan a few flicks & it’s never done it again.
I have opened my opus a couple of times & while it was open I took the fan out & took all stickers off it & sprayed it including the windings with spray on 3 in 1 oil.
Hey wolfdog you sent me link in the other thread for the adaptors from alixpress, they fit good & are right angle.

SIGShooter · 2019-03-23T00:47:42.000Z

My fan also started making noises last year but a squirt of Tri-flow after I took it out fixed that right up

Nev · 2019-03-23T01:05:09.000Z

Is triflow an oil?

Glad to hear that. I did not have time to search the thread because I was on my way to the trail. I am curious,where is the link to those?

I thought I got them all on Ebay.
