That is all well and good. But none of it answers the questions I asked.
In addition mine does not do it with 4 x Sanyo NCR18650GA’s…. 3500mAh each. 4 x Sanyo GA’s [3500mAh ea.] = 14,000mAh … Additional 400mAh from the K’powers
teacher——-I tried to answer you as far as I know from reading here—I thought the first instance of the New problem was when Wolfdog tried the replacement fans—yesterday he mentioned that other 3100 had this shutting down on discharge problem
gauss163—I thought about the IR after my last post—most of my cells are low resistance—as far as ambient temp—I have mentioned my wife keeps this house like a meat cooler—-one of the things I see is—all of his chargers are/maybe coming from the same lot
the only way I could make my 3400 replicate the first discharge/charge reset was to use my Littokala 2amp PS—-with this PS as soon as you tried to charge 4 cells @ 1 amp it reset
I understand teacher! Your charger is just like King Opus that I killed,It has NO issues,be grateful. I have had 2 chargers that could not handle 4 x 18650,that is why I am determined to get this one or another one working like it should.
The results I post later will show the difference b/w 3 or 4 batteries discharged when you have a charger like the one I have now. Lastly, Jon only discharges 3 batteries at a time because of this issue and the other[reset] that I mentioned in a post yesterday!
HKJ and I have been exchanging emails/photos of my board. He has been tremendous help in pin pointing the destruction of King Opus. I will post that later.
I am testing 4 X 30Q Now,10 cycles only,basically new. I will find out soon enough if it stops or if it can handle 12,000mAh. It could not handle 13,600mAh[4 x KP 3400.

Although not mind boggling this will give you an idea what the difference is in charging 3 X 18650 3400 VS. 4 X 18650 3400. Same KeepPower batteries.
I believe this is evidence that numerous stoppages during discharge directly relates to over blown and inaccurate capacity readings.
- 4 X 18650 3400mAh Keeppower-Numerous stoppages ~15 lasting 90 sec. to 2 minutes.
Four slot median:3278mah
Average time: 3h55m
–3 X 18650 3400mAh KeepPower
Four slot median: 3096mAh
Average time: 3h3m
Difference: 282mAh and 52 minutes longer for the 4 x 18650 3400mAh
Obviously the stoppages ADD time and the also add mAh because as the battery rests, the voltage goes up ~0.03v to 0.06v and that is measured AGAIN!
The solution, other than what I am trying to do[Delta destroyer] is to do what Jon does and only put 3 batteries in!! I can not accept that,at least now I won’t!
And a stellar job you did my Louisiana friend. :+1: … Thank you.
All I was attempting to ascertain was when the heat problem was first noticed as wolfdog has now mentioned it has happened in 3 of his 4 OPUS chargers.(1)
“I” did not recall any of that being mentioned until the last day or two.
So I was trying to determine if this had been an occurrence all along and just not been mentioned OR if I had missed the mention of it in all this vast quantity of material.
The more I think about this chops the more I like it! You know, being preventative and all………….
I am gonna see if I know anyone who knows anything about 3D printing…. cause I sure don’t.
100mAh difference. But you see why I love King Opus. Out of the 4 chargers it was the most consistent and was closer to HKJ’s numbers than the other Three.
