Re: The 3500mAh heavyweight division: Sanyo NCR18650GA vs Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E

Beautiful test! Good job! Thanks! Have you considered retesting? I am wondering if you tried different cells if the brands would perform equally to the result of this test. Hopefully the cells are consistent though, just wondering. Also, if you still have these exact cells, I wonder how they have c...

Hell I want the biggest baddest cell and use it at 1/3 or 1/2 of is discharge rate thinking of a Samsung 25r 6p for 80 amps 80v 20s. I think 4 cycle rate this is where we need to go.

advice for replacing bad cell in 3s2p 18650 pack.

... like .2 volts with half use and I assume it is a bad cell. I used the panasonic ncr18650b cells on these packs a couple of years ago. My question ... the bad cell, do you see any issues with replacing it with a new Sanyo NCR18650GA 3500 MMAH cell? I have some of these laying around from my ebike ...

What you are talking about? PF is 2.3€/qty and you have to buy 540pcs to get this price 29E is 2.14€/qty if you buy 200pcs. Shipping to Europe is always about 15€ even if you buy thousands of them. Tumich sells 29E ~2.10€/pcs inc shipping. Little bit cheaper but buying from Nkon store should be more...

Re: Cycle Life tests or experience with Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E

When the Panasonic NCR18650pf came out, I logged one cell for around 300 cycles. Charge to 4.18v at 1.3A, 0.2A cut-off. Discharge 5A to 2.7v. I can't seem to find the sheet but it lost about 15% capacity.

Re: Cycle Life tests or experience with Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E

It is hard to answer even if i have all three cells measured for their cycle life. When you plan to use only 50% DoD average,... Why buy a 3500mAh cell if you only use 1750mAh? The " 50% DoD average" principle means that most of the time you are using only less than 50% capacity of battery but you ...

Re: Cycle Life tests or experience with Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E

Imho the cycle degradations main factor is the silicone in the anode, less the cathode material. All 3500mAh cells use Si-C anodes, whcihs significantly reduces cycle performance. (Afaik the newer 21700 high capacity cells do not use Si-C anodes, that's why their energy densiotiy is lower than the ...

NCR is the "bussines name" used by Panasonic for their cell production line. The base chemistry principle (cathode active material) is known as NCA which is shortcut for – Lithium Nickel Cobalt Aluminium Oxide (LiNiCoAlO2). So NCR chemistry ...

Re: Cycle Life tests or experience with Panasonic NCR18650GA vs LG MJ1 vs Samsung INR18650-35E

I can also say that Sanyo NCR18650GA has very similar cycle life with Sanyo NCR20700B and this two NCA cells have the worst cycle life (under the same 100% DoD test) from the Panasonic 18650/20700 actual production line. Cells like NCR18650BM, Tesla 85kWh or NCR18650PF ...
