3500-mAh NCA cell, Samsung, LG, Sanyo, Panasonic

opperpanter · Jun 10, 2015

Couldn't find any topic on this cell, so here's one

Samsung INR1865035E

Some curves: http://www.dampfakkus.de/akkutest.php?id=577

capacity 3500mAh
Minimum Capacity 3350mAh
Voltage 3.6V - 3.7V
Charge voltage 4.2V
Discharge current ( constant ) 2,5C 8A
max . Discharge current ( constant ) 3C 10,5A
Charging current 0.6C 2000mA
discharge voltage 2,65V
Protection circuit PCB No
Positive flat ( FlatTop )
Chemistry LiNiCoAlO2
Diameter 18,55mm ± 0.1
Height 65,25mm ± 0.15
Weight 48g ± 1
CC-CV charging method

If it really gives 3450mAh, it's a great improvement over the 29E at the same weight.

32E was nice improvement, and this is even better one! But the prices are corresponding unfortunately, 29E is extremely cheap.

TheBeastie · Jun 10, 2015

Looks good! Yeah nothing beats good old Lithium Nickel Cobalt Aluminum Oxide chemistry cells.

Nobuo · Jun 10, 2015

the panasonic B series didn't get the high density market, but those ones have a more reasonable price to be top summit density

we are leaving the 18650 <3Ah energy/price best choice and entering slowly the >3Ah

Here the two 3.5Ah cells with a good entering price

Looks like 29e got cheap lately? To be replaced by 35e?

Punx0r · Jun 11, 2015

Does the discharge voltage rating indicate the voltage sustained (average?) during the rated 8A discharge?

I doubt it will get replaced, especially now with such low price, it has large market. I mean the 22F and 26F/H are still being sold

okashira · Jun 11, 2015

Someone send me these cells and i'll do some good tests. Dampfakku's curves and testing sucks.

riba2233 · Jun 11, 2015

Yeah, his results on 32E don't match lygte's... I'm talking about 10A curves, must be some kind of error there.

I know, but couldn't find any others :shock:

This cell outperforms Panasonic NCS18650PF in capacity at 2A, 3A and 5A with more than 15%. Only drawback seem to be 8A cont vs 10A cont. Add one more parallel string and this cell seems as a clean winner! 5A:

riba2233 · Jun 13, 2015

10A curves on 35E on dampfakkus are probably wrong. They should do 10A at almost full capacity.

fellow · Jun 13, 2015

Here is the 10A graph Riba2233 is referring to:

LG MH1 shows very strong performance at 10A. At 5A, both perform almost identical (2.8Ah, 9.4Wh~9.5Wh).

LG INR18650MJ1 seem to be the latest "killer" cell: https://www.akkuteile.de/lithium-ionen-akkus/18650/lg/lg-inr18650mj1-3500mah-3-6-3-7v-10a-lithium-ionen-akku-button-top/a-100801/
3.5Ah, 4.2V, 10A cont, 49g, LiNiCoAlO2, 8.6€/piece.

tumich · Jun 14, 2015

Panasonic's 18650PF can dc up to 2,5V (safe for 2,8V). So it's not good comparison with cells up to 3V.

Btw I have these new Samsung's and will testing them dc. On nklon they have wrote that 8A dc. I'm curious how many mAh will under 1A and 8A

I hope they are good for low discharges like 29E.

tonysako · Jun 15, 2015

Anybody have info on these 2 cells LG INR18650MJ1 - 3500mAh 3.6 - 3.7V, 10A lithium-ion battery and Samsung INR18650-35E 3.6V - 3.7V 3500mAh love to see some info on these two? not sure if its been covered or not.

LG MJ1: http://powercartel.com/2015/02/test-results-for-lg-inr18650-mj1-3500mah-18650-li-ion-battery/

LG MJ1 5A test:

LG MJ1 10A test:

Those cells seem to differ a bit as those 2 samples are not overlapping 100%. Difference is roughly 0.1V under 3.0V (new cells are heading this sub 3.0V way). This can be problematic when used in series without BMS at 10A. 5A looks a bit better, but not perfect if we want to extract more than other cells (and we do). Other than that, I don't see a reason to use anything else besides unknown cycle life. This monster cell touches 3.3Ah mark at 10A discharge! MH1 is less than 3.2 ah at 10A discharge. Both measured at 2.5V cutoff. Choose your LVC wisely!

LG MH1 vs Samsung 35E at 10A:

Cowardlyduck · Jun 16, 2015

Loving both these new 3500mah cells.

Looking at the prices, they are not too bad, and I will seriously be considering these for my up coming battery builds for my recumbent and Stealth using ~60 and ~180+ cells respectively.

Cheers

good thread. for low amps the 29E probably is one of the best bang for buck, but from what i know it is not the same chemistry as 32E or 35E. the latter are NCA i believe - can someone confirm? Unfortunately there is no info in the datasheets..
At the moment i built a 10s10p pack out of 32E for a friends e-bike. As his electronic is programmed for LiPo and cuts off at 33-34V or in this case at 3,3-3,4V per cell, i was looking for highest possible nominal voltage at 2-3A current per cell. after some research i found out the 32E was best bang for the buck for this purpose in these days.

seems like the newer cells come more and more closer to a nominal votlage like LiPos have it - at least the high capacity cells and at very low amps

LG MJ1 had the throne for the whole 5 days. Meet the LG MJ1 killer, the Panasonic/Sanyo NCR18650GA:

Time to change the thread name again?

GA .. Panasonic monster cell .. Sanyo branded to keep the name alive.
Yes the 35E measurements are surely faulty. It deserves a good test.

Cowardlyduck · Jun 19, 2015

But look at the price! It won't see many uses at that price...at least the LG is more reasonably priced.

Your list is missing few cells, like panasonic BE and BD, and Samsung 32E. They are all 3200 mah 10A cells. So, panasonic PF has nothing to search for in this list

@Okashira, are you aware of LG HG2? 3000mah, but 20A unlike 30Q which is 15A rated.

fellow · Jun 20, 2015

Riba2233: Thanks, that LG HG2 cell is very interesting!

I was looking for a reliable 10A charts for BE and BD cells, but could't find any. Assumed that 35E is sucessor of 32E. 32E 10A graph is missing Wh data:

tumich · Jun 20, 2015

Do you know the temperature of Panasonic's 18650PF under 10A dc?
