I will post the full review later today, this includes also charts with a time axis and all HI-MAX curves in the same chart (Like all my other battery reviews).
On what voltage is undervoltage protection of these cells?
žI just continued discharge of this same cell, put end voltage at 2,50V, so Ill see, fif anything happens.
I still didnt had any cell, as far as I know, with working undervoltage protection - and im ordering good, high capacity Trustfire flames.
It delivered 99 more mAh to 2,50V. (from 2,80 to 2,50V)
Im not aware of undervoltage protection kicking in… (but I didnt watched the charger whole time - if that matters…)
Can somebody help me understand this - I asked this questiuon on several other topics, still struggling with answer.
The under voltage protection is somewhere between 2.0 and 3.0 volt, you order the protection chip for the specific voltage you need. That is the theory, but for the number of chips used here, the manufacturer only have a few fixed voltages to select between.
Im ordering them from kaidomain.
But still didnt found any cell with undervoltage protectiion : (and I dont want to discharg/torment them all to 2,0V just to see weather undervoltage protection is on 2,2 or something like that)
Im testing third cell.
COnsistently, these cedlls are nothing better than trustfire flames Im getting from kaidomain. Maybe even worse in some aspects.
No I dont think thats it. I just think that it happened what over time often happens with originally good quality products - quality drops. Unfortunately for us.
Although its little suspicious that there is nowhere “Himax” mentioned in seller’s listing, so listing cant be find if searching for “himax”.
PS: But its still a puzzle for me how HKJ gained somewhat better results than me… I dont know.
But my results couldnt be so wrong. I have Trustfire flames as reference (tested on same equipment), even if results are slightly off, they are pretty the same as results for trustfire flames.
To think that this dude won’t budge when I tried to send him a best offer. If these are quality cells I won’t mind, but for this kind of crap? Goodness, I will file a paypal dispute.
It just arrived today and delivery time was closer to three weeks. They’re all currently being charged. All came charged at 3.59v or 3.60v. Now I can’t wait for my Apex 5T6 and Big Head K8 to arrive. :bigsmile:
