I will try to answer all the questions in this post.
I ruined my charger last night,Jon did not replace it, he gave me a very good deal on a new one.
Every Opus[had four] I owned or tried worked. They have variances. The Best one which I ruined last night was the ONLY one that never stopped[because of heat] during the discharge cycle,Therefore it was MORE accurate because it did not measure mAh again after stoppage.I actually watched these chargers once the mA read”0”. sometimes they stop for 2 minutes or more until the batteries cool. The voltage goes up b/w 0.03v and 0.06v during stoppage. That is measured again,hence the inaccuracy.This happened every 7 to 8 minutes with this new charger.
Basically the longer it takes to discharge the higher the mAh reading and more Inaccurate those readings are.This is after using the same batteries and comparing time of discharge and capacity results.
Before I forget. My Orbtronic comparisons were in a post earlier today.New charger was around 45 minutes longer and was ~175mAh higher.[Four slot median]
What I have simply determined in the last few hours is this. A fan like the delta would eliminate this problem. also, the variance in the charger also plays a role because this new charger has the Lite-on as did yesterdays catastrophe. So I put old chargers fan in new charger and it STILL has stoppages. That tells me something is a little different electronically,i have no idea what it may be.
I will admit I am more picky than most. I also am a great observer and write these stats down and also watch the charger when it is stopping. So I am not imagining the inconsistencies, I may be bothered by them more.
I am driven to get this or another charger to work like the deceased one! Like HKJ said, more air flow should solve your problem. I believe that. sometimes you have to improvise in order to eliminate an imperfection.
I have 6 X 4BAY quality chargers. the ONLY reason I got the Opus is for relatively accurate Capacity tests. The One I have now[after two tests] seems to be the most inaccurate of the Four.
I know I did not say exactly everything I wanted to. Those thought have escaped me. It bothered me a lot that I ruined the Opus becuase i knew that it would be difficult to find one as accurate.
I may drive you nuts along w/ myself,but I am determined to get this one or the next one to be as accurate as the deceased Mr. opus.
I emailed someone to splice/rewire/mod my remaining Two Delta fans,THAT IS THE SOLUTION FOR THIS CHARGER,I AM CONVINCED,MORE AIRFLOW! :+1:
If I fogrot anything I am sorry,I am a bit delirious today,actuall 4 days in a row w/ not enogh sleep,good night,good weekend,Capolini/wolfodg/Camilli/Volpini!!!
EDIT:I THOUGHT I POSTED THE CHARGE/TEST RESULTS EARLIER…HERE THEY ARE:
This is with the same 4 x 18650 Orbtronic batteries and discharged @1amp.These batteries were cycled 470 times bought on 12.21.2012.
Old charger:Time:2h48m Four slot median:2784mAh Done last week.
New charger: Time:3h34m. Four slot median:2955mAh
Diff: 46 minutes/171mAh. I do not mind the extra time but it correlates with the Inaccurate capacities.
My final test in the KP 4 X 18650. I will have those results before I go to bed,I would guess at least 150Mah off and an additional[minimal] 50 minutes more time. I will EDIT and post that tonight.
In order to get a better comparison of these tests and how accurate Mr. Deceased Opus was.This is a good barometer.
30 Q Brand new-
HKJ-2884mah…………….Opus Four slot median:2910mAh
