Dolidada cells with low capacity and an inaccurate Zanflare C4

Lux-Perpetua · 2018-05-31T09:49:30.000Z

I just learned that I am not the only one having these issues with the C4…

OK, it seems I found the reason for varying measurements. Temperature swings. When I’m not home heating doesn’t work and temperature goes down by a couple of degrees. I didn’t expect this would be a problem as the cells being measured would be very warm after I return despite quite low ambient temps. But I took the charger to my fiancee, she measured the 18650B 3 times within 30 mAh. Above 3500 mAh. So I can disregard all the measurements I did so far, but it doesn’t mean there’s a problem wit…

…as a result of all comments ordered 5 dolidada for $18.59 .Good price for 5000mAH battery and the name it’s so beautiful.
I will test with my original Lii-500.

If they change their name to ’ a do do do, a da da da ’ … I’ll order 5 more, promise!

I love this song… :heart_eyes:

Oh shucks…I have forgotten and just realized that that song was sang by Sting!

Will listen to it again….

Sting was singer for The Police

I have concluded my Discharge test using my iCharger of a 30q after 14h, 07min. Capacity: 2,860mAh @ .20a — photo in post # 11

snakebite · 2018-06-01T00:09:41.000Z

from what i see peeking up from the + end those look like the ebl 5000 i got a bunch of.
every one was above 5000 after 2-3 cycles.
but the results with your 30q’s leads me to believe that analyzer is inaccurate.

That’s my long-time observation too….when I started in this hobby almost 6 years ago, I started out with laptop pulls only, no analyzing chargers then, the reason why I got the iCharger (and the Pila IBC and Maha C9000) at that time.

I remember that the only time a cell rating had actually reach or exceed by a bit its mAh rating on the lable from reputable manufacturer is when I set my iCharger to discharge down to 2.50V.

Innacurate cheap analyzing chargers? Welcome to the real world fellows. The current sense resistors used by these devices feature 1% tolerance, let's just start with this, and there are more variables over the table. I believe my Lii-500 measures close to 2% less, based on my observations for various cells.

Cheers :-)

I wrote an honest review about the Zanflare C4 on Gearbest’s website. After that, their customer service team contacted me in order to solve the issues I have with my device. I explained in detail about the high deviations concerning the capacity measurement incl. the fact that charging slot #2 always indicates much more than the other slots.

So…eventually, this is what Gearbest calls “problem solution”. Thank you very much! :person_facepalming:

Dear Thomas，

Thank you for your patiencer.

This charger comes with a volume detection function. Voltage accuracy deviation 2; Current accuracy deviation 5; Time accuracy deviation 1. The capacity is tested by charging voltage, current, and time calculations. Due to the fact that it is not a special compartment, the current market can only achieve a 10 accuracy deviation.

The use of interference Including factors: such as the ambient temperature, humidity, battery type, if the battery installed contacts are good or not and so on. For example, if use different brands of the sub-capacity tester to test, there will be some deviations.

Thank you for your understanding.

Best Regards

Received my 5 Dolidada’s looks very nice , firsts two of them is allready in my Lii-500 for test.

Sting…… this is one of my all time favorites by him!!

No battery, charger, or light content whatsoever.

But fond memories………

Lux-Perpetua · 2018-06-15T12:23:02.000Z

Well…talking about having faith in Zanflare’s C4 I’d rather listen to this today…

tatasal · 2018-06-15T12:25:31.000Z

Excellent choice from Sting’s collection! Enjoying it now….

Please keep us updated about the dispute. I assume voltage will drop significantly when you use 10 or 15 amps on these cells.
