UDO, you mean you are “absolutely” sure your e-bike limits itself for max 14A amp draw (≈700W of power)? I reeally doubt it.

A 14S3P pack of NCR18650Bs, though slightly lighter, would be a baad idea, imho. 3P NCR18650Bs aren't high drain cells and, comparatively, would barely deliver slightly more current at the same output voltage than a single LiitoKala 26650-50A/B.

For a vehicle, no matter what, it is advisable to use sufficiently high drain/power cell packs. Either that, or its throttle response/slope performance will suck, not to mention battery life would also crumble.

It is also possible to build hybrid battery packs. If, for example, you were to like the idea of having a battery pack combining slightly less weight and capacity but preserve/enhance top power output, you could then assemble, for example, a 14SαP pack, for α = sum of a top notch high drain 18650 plus our 26650. 

 

Cheers Party

absolutely.test equipment is a triton hobby charger.
i still have 2 and will test them over the holiday weekend.
the other 4 from the order are in box mods and doing great.

Are you planning on checking the capacity?
If you do, give us an update please as to results and test equipment used. Thumbs Up

They (LiitoKala 26650’s) seem to be staying fairly consistent as time goes on. I hope it continues. Wink

Are you at all interested in modding my Utorch UT02 (Manker U21)? I would certainly pay for materials. Maybe work a trade of some kind? Maybe a new in package Lumintop TD16? Or something else.

update.
i discovered high resistance in my test rig.banana plugs to my holder were losing their tension.
charged the cells again and started another discharge.holding 4.13v @ 1a at start.
was 3.96v.
so these are likely better than we thought.
stay tuned…

What do you want done with it? I like a dedomed XPL in it, but some might prefer it domed.

I received four from GearBest yesterday, first charge>discharge cycle @ 1A down to 2,8V :

I started the cycle this morning before I went to work so the cell voltage recovered a bit.

I am recharging them now :

What is the max current draw you get these from these in a direct drive set up? I just bought 6 shipping was 11 USD so i hope they do well.

These are a bit wider and a bit shorter then most other 26650’s, it fits like a glove in the L6, it doesn’t fall when inserted it just slowly lowers itself to the bottom.

Gonna get some serious amps mangled from them pretty soon… 

The BMS low voltage/under discharge protection works well. I accidentally hard-shorted the BP+/B- terminals while assembling the stuff, a lil smoke crept away…  Had to hook the thing up to the charger board to relive it. Quite interesting to notice my multimeter could actually measure some volts at the output terminals after the “accident”, a below 1Hz voltage signal oscillating between very high 6s and low 7s.

 

Cheers

Yesterday i received my 2 pcs. I put them to the test with my Opus.
1 cell at 1A – 5434mAh
2 cell at 1A – 5534mAh

I will test them these days on my L6 and will see how they perform.

Received one from Banggood. Did discharge test in Opus BT-C100: 4898mAh. A bit disappointing. Impedance test afterwards showed 76mR.

Just noticed that the product listing has disappeared from Banggood…

Interesting, I picked up some of these because of good reports earlier, but I have not tested them, waiting for some nice new light. Maybe I will test them when my test charges arrives and then put them back at storage voltage until I have a need for them. They sure seem like a pretty good bargain.

Well HKJ has now reviewed these cells & says about them “The cell live up to its rating and is one of the top performers for 26650 at the current time.”

Thanks for that link! As far as I am concerned this pretty well verifies what we thought all along. Thumbs Up

Which brings me to another realization.
If HKJ’s “Discharge Capacity numbers” are accurate, and I feel sure they are; my LiitoKala Lii-500 is much more accurate than my Opus BT C-3100 v2.2 when measuring “Discharge Capacity”. Interesting…….. Wink

Edit: Forgot to say…… Facepalm
My Opus reads consistently high, and from some of the Opus numbers some others have posted in the past, mine appears not to be the only one. Wink

Yes I think that it is generally accepted that the OPUS is a little “optimistic” in terms of cell capacity.
My OPUS certainly is.

“Optimistic” that is a very scholarly way to say that!! I “b” impresseded. Thumbs Up
Do you happen to be a “scholar” ??? Wink
Innocent
Edit: I was doing some looking back on things I had written down, and best I remember Ian; you and I compared numbers from LiitoKala 26650’s done on both chargers. Our numbers were very comparable for both chargers as each of us has a Lii-500 & a BT C-3100. Pretty interesting results for two different continents. Wink

Yes our numbers were almost identical.
These cells have proved to be pretty uniform in capacity tests done by many different members Thumbs Up
It is nice also to now have HKJ“s review to confirm what many members have experienced with these cells.
Also the Lii-500 chargers seem to be pretty consistent as well Smile

Just ordered qty 4 of the singles - shipping to us is only $3.73 now for qty 4, much less than previous. I was able to use some pts so got it down to $21.95 shipped for 4.

After 40-50 cycles mine still test at 5200 mah on my opus. I do tend to baby them. No more then 1 amp charging usually very rarely 2 amps. And if no other cells need charging I’ll let them charge at 500mah overnight

Edit wanted to add my opus slightly undercharges. So capacity may have been slightly higher if it was charged to 4.20 or higher. I regret not getting another 4 of these cells last summer. I regret not stocking up on old xpg2 as well. But I digress.

My vc2 goes to the high end of 4.23-4.24 which is fine with me its within spec. My liito 100 overcharges. Just saw the other day 4.27 and was on the right setting. Wonder how long its been cooking my cells.

Did these work in your L6 without modification? I was wondering if they will need a solder blob to work in series?
