Review request for HKJ [Rechargeable Batteries]

To be honest I find more interesting… How the new arrivals of today will perform

I m hoping the 3000mah are a nice rewrap of a 30Q a hg2 mh1 or such

I am not putting them on the list just yet. I they are still interesting in a couple of months I might reconsider.

No problem at all… 0:)

Any chance you would do some LiFePO4 batteries of any sizes HKJ? I have an 18650 and AAA size ones that are doing fine by me. Albeit with shorter run time, and somewhat less output on Turbo (DD). I know on paper these are not that appealing…

Not at the current time, I have way to long queue.

I would also require suggestions about some LiFePO4 to test.

I wonder if SKILHUNT is one of the fakers when it comes to capacity or if they are one of the honest manufacturers.

I have a few FASTTECH links to the LiFePO4 batteries in 18650, 16340 AAA and AA sizes for you to test if you have the time.

I am mainly interested if they live up to the MAH claims and how they hold up during high loads. I do not know if you have a way of testing their supposedly higher recharge rates either.

Thanks and if you have too much already on your plate, no problems.

I have saved the links for later.

I just hope, somehow, you could put the latest state-of-the-art 18650's to the top of the queue. These are the cells, I think, that are of most interest in which we have no test results on. In this vein, it would be much better to test the original cell brand, not the re-wraps that are so common - obviously this is getting harder and harder to figure out though. But if you stay with the latest offerings from Sanyo (GA), Samsung (30Q) and LG (HG2), that would be a great start. Also it's both selfish and thinking of you -- rewraps are sort of a waste of your precious time and energy.

Right now, we have a slew of high performance cells coming out at 3000 mAh, and moderate performance ones at 3500 mAh - these are the ones.

Thanks btw for all this great data!!

X2! Very hot topic these days.

I would like to test the soon, but with all the rewraps I got in queue it will be some time (See picture in the second post).

MECO batteries… why so cheap? Meco - Buy Meco with free shipping | Banggood Shopping

BangGood got a notification from UltraFire to stop using their name, so MECO is the brand name they are using in place of UltraFire. That's the word I got from a BangGood rep. One day I noticed all UltraFire brands dropped from the BG site, so I asked. I was hoping they would bring back the UltraFire ZY-T11 clone under MECO branding, but it's not there, yet.

I sure wouldn't trust the MECO brand cells, same as not trusting UltraFire cells (real capacity, charge cycles, etc.).

Thanks for the heads up! They are SO CHEAP IT’S SO TEMPTING but since it’s a re branded UF I will stay far far away

Oh yes please.

Both the 3500mAh LiNiCoAl and the 3000mAh LiNiCoMn are pushed by the major brands at the moment and it would be very nice to compare GA, BL, MJ1 and 35E, as well as HG2 and 30Q with each other and its predecessors.

We all know that rewrappers often use these cells, but we never can be sure which it is and which one it will be in the future - as they are also known to bait and switch. Buying the Panasonic/Sanyo, LG or Samsung cells (from a reputable source) gives so much more value. There are only a few tests missing. Perhaps you could adapt your queue, slightly…

You can do this already if you research a bit and don’t mind German text around the discharge graphs.

Well, I truly don’t mind. But as of today even dampfakkus.de does not yet cover the GA, the MJ1 and the 30Q in the range of 2-5A.
And the HG2 was only added in the last 48 hours. :wink:

dampfakkus has a big advantage compared to me, they do not test at low currents and only test one cell! This means they can do their test in one or two day(s) and not one week as I need.

Can’t thank you enough for your thorough testing. That’s why I would never ask for a change in testing procedure - but I do second TomE’s motion for a tiny little shift in the queue.

I was not talking about dampfakkus.de, but the German flashlight forum. Just google battery name + “test” and you’ll find it.

Edit: I don’t see any rule forbidding links to other forums so here we are:
Samsung INR18650-35E
Panasonic/Sanyo NCR18650GA
Samsung INR18650-30Q
