The 3500mAh heavyweight division: Sanyo NCR18650GA vs Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E
Hi guys! I’ve got 4 3500mAh batteries from top manufacturers and I’ve tested and compared them. I think it’s interesting not only for me, but also for you, the guy who is reading this:)
For those who prefer watching than reading I’ve made the video version of this test:

Thanks for this.
Which one got the hottest and which stayed the coolest at 10amp discharge?

brumbrum, I didn't measure the temperature. I didn't even touch them while in progress, to not affect the results. I allowed myself to touch them only after discharging was done and they all were quite hot. I'd not recommend using any of them at 10A without active cooling.

To see cycle test for them is my ultimate dream 
So then I can decide which goes to my future i-miev 40kWh battery extener.

Re: The 3500mAh heavyweight division: Sanyo NCR18650GA vs Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E
Interesting! I did a test of the same cells including the new Sony US18650VC7, it was published 5 dec. 2017. However i used 40 cells from each brand, as you can see in my data one cell is NOT ENOUGHT for any kind of data cells the capacity can vary between 200-360mAh in brand new cells. If you look at my graph at ca 4:00 you can se that ANY CELL could have won if just used ONE sample!
[youtube]https://www.youtube.com/watch?v=Qpm91Itv6k8[/youtube]
Also Sanyo and Panasonic is NOT THE SAME COMPANY! They are different companies but Panasonic OWNS Sanyo! Its a huge difference! Sanyo cells are also made in Japan but at different factories, except for some new cells (2017 with other heat shrink plastic, like the one you got).
Your test is internering BUT not scientific since you used just ONE sample. The result is more or less RANDOM. Please use at least 10 cells in further test,please. And DONT call sanyo cells panasonic! They are NOT the same! Both GA cells are made by SANYO but the china version is made in china!

The Battery Doctor, I've stopped watching your video when you said you used LiitoKala Lii-500 as tester
. You didn't follow the prescriptions of the standard, you didn't even follow the manufacturers' prescriptions. You can use 40 cells or even 400 cells of each brand but if your testing equipment is LiitoKala Lii-500, then your results worth NOTHING. And you call my test "not scientific"?
Panasonic has bought SANYO and owns its thechnologies and rights to use them in his own production (which he does). The plant in Suzhou, China belongs to Panasonic, not to its SANYO branch, so the second GA is Panasonic, not SANYO, and they bear the same model number and are sold as just NCR18650GA, which proves that they are the same company with factories in different parts of the world.
And please stop spamming. You've copied your post under my video on YouTube for what? Are you going to send me text messages, e-mails and letters with the same text?
P.S. If you have really bought 40 cells of each brand then you can afford buying a normal testing equipment i think. Throw your Lii-500 out and use something serious before calling others' tests "not scientific"

The battery doctor.... you are kinda right. You got a legit point. Nevertheless I must disagree. Correct me if I am wrong but afaik all cells have a quality test and those under the standards are discarded and sold to third party companies. They are rebranded as whateverfire and sold for cheap.
So "maybe" I repeat "MAYBE" testing more than one could help. If you need 10 cells to test a top class brand....That brand Is just crap.

Wow the heat is on. So at what rate would you use these cells at in an ebike pack for decent life ?
10amp ? 6amp ?
Or the cells hotter then this conversation ?

No matter at what rate you gonna use them. The only thing which matters is the quantity of cells in the pack. If you are going to buy a couple of cells for a powerbank, then any of them would be good. If you gonna build a pack of 100 cells, then the difference will be noticeable.
For example the 0.51Wh difference between Sanyo and LG @10A would result in 51Wh in the pack, which means 5 batteries. So instead of 100 Sanyos you would have to buy 105 LGs.

The temperature have big effect on the energie(wh)you can take out of a cell.
i like to see how meny Wh,s these cells give@ 30/40 degree celsius

I want a 72v 20ah pack @ 70amp . would like it to fit in a em3ev triangle bag. So 10p I would need or 12p. This is getting big. 240 cells. I think samsung 25r. (25a cell )for less heat and less parallel for 70amps. But a bigger battery.
I do want 800 cycles.
Meaning I need cycle life and low sag.

What about Boston-Power Swing? It's an impressive cell in terms of cycle life.

I think heat is the problem for cycle life and sag. So is a 25amp cell better suited for higher amp ebike pack.. If I had a emoto for 40ah of battery. I see this. Always a balance and a compromise. Till we get the 5 volt cell.
Re: The 3500mAh heavyweight division: Sanyo NCR18650GA vs Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E
The heat generation and voltage sag are caused by the cell internal resistance (IR). You can choose two ways how to deal with this issue. You can use high power (HP) cells with low IR such as your mentioned Samsung 25R. Then you can operate at 3-5C average discharge current without significant effect on cycle life. Or you can use high energy cells (HE) such as this three cells but you need to stay at 1C max average discharge current for good cycle life. The average discharge current already counts with using short (up to 15sec) peaks with maximum allowable current per cell.
However, for cycle life, no matter if HE or HP cell is used, the most important parameter is average Depth of Discharge. For example I measured when only 50% DoD is used (in the range 100%-50%) all of the modern cells, again no matter if HE or HP, loss only about 7-10% of its nominal capaity after 1000cycles! But when you are using 100% DoD most of the HE cells are practicaly dead after 400-500 cycles. HP cells can do 1000 cycles with about 70% of remaining capacity.
Also when using a low average DoD you can allow much higher average currents or using 1C fast charging without significant effect on cycle life.

I was looking at this pack http://powervelocity.com/index.php?id_p ... er=product as it made of the panasonic cells. Not to many 72v volt 20ah packs on the market. Usa base.
Re: The 3500mAh heavyweight division: Sanyo NCR18650GA vs Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E
Heat basically leads to "faster chemical reaction" which increases the performance.
-> less internal resistance, so less voltage drop and more Wh
If you going to abuse your battery, it makes a lot of sense to warm it up (RC model pilots/drivers usually doing this with the LiPos for records and such extreme things).
The bad side about a battery that is heated is that aging (calendar life) will suffer ALOT.
Thats also at least one big reason why the cycle life gets so worse if you use the cells at specified C rate (like 20A on a 25R or 30A on Sony VTC5) because the cell becomes VERY HOT at the end and this hurts.
It's usually the internal resistance which will get worse and worse than..
For long storage it would be optimal to put the battery in the fridge, and during usage around 20°C.

Perform the same test after 300 cycles and you will be surprised with the results !
GA is excellent in the first 50-100 cycles but the internal resistance rises so quickly that even an old 18650PF beats it after that.
