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

My results:
Opened dispute!!!
Please keep us updated about the dispute. I assume voltage will drop significantly when you use 10 or 15 amps on these cells.
Just sharing the tested capacities on the 5x Dolidada 26650 batteries I bought a few months ago from this AX listing. I thought US$19.xx for 5x 26650 batteries is a very good price at the time.
These were all tested using 0.5A on a Zanflare C4 when I first received these batteries in late May 2018. I was initially quite disappointed with these results, as there were reports these batteries had measured capacities closer to 6000mAh.
Battery #1 & 2
Battery #3 & 4
Battery #5
I repeated the same measurement (0.5A) on my Liitokala Lii-500, which yielded even lower capacities!!
Battery #1
Battery #2
Battery #3
Battery #4
Battery #5
Bad, quite bad Dolidada.
I recently discovered that my Lii-500, on the other hand, is quite accurate with regards to capacity testing:
As things are now, it seems like the available production of PLB 5500mAh cells is not being used by Dolidada, LiitoKala or whatever cheapass rewrapper.
^:)
Any reason why the end voltages are 3.17V and 3.21V, as opposed to 4.2V?
The cells were likely still being charged back up when he took the photo.
I lost the dispute,
Alie judge ask for video ,Lii-500 pictures was not enough.
They offer resend and full refund but in that case the cost of the post would have been to high for me ,so I choose to keep the batteries.
