Re: BRAND NEW CELLS 18650 SAMSUNG/SANYO/PANASONIC 3500mAh

Post by Hummina Shadeeba » Mar 09 2016 4:48pm

i know what a c rating is and amps and volts. there is often a peak burst number batteries are rated at. sometimes not. there often isn't a time period given. wondering how important even the c rating is when they start throwing in a burst current. it makes it hazy. will you damage the batteries or not. and can it be assumed that a burst of an increase of roughly 50 percent of the max continuous is ok..for unknown time. is it jsut defined by the temp it will get to? what temp is too much?

ive seen discharge being used to discribe batteries.
Ive also read about batteries not producing any current when there is too much draw. maybe there is somewhat of a fuse that hits? dont know just seen discharge tests showing this.
i understand this is the for sale section but i cant find a burst number for these cells and am questioning burst numbers period.

> Well almost everywhere you see 18650 cells or Lipo or Lifepo4 you will see some reference to C value.

Yes, of course I have seen those horrible "C" numbers and I do know what they mean.
And everytime I wished, they would fire the marketing people that came up with this confusing term.
The "C"s are mainly used in the LIPO-world for the RC-users that are impressed by such "hype" words.
When you Google for it, you will find how to convert the ominous "C"s into the real-world "Amperes" (Capacity X C = Max Amperes)
In the 18650 specs you rarely find "C"s but the Max Amperes

Here is a correct and very helpful Spec for a battery - that also shows the "BURST" values that Hummina was looking for :

Note that the word "discharge" in this spec does not stand as a term for CURRENT,
it is just meant to differenciate it from the *charge* current in the last line.

Cheers, Ulli
PS: Note that the numbers in the picture are for a DIFFERENT BATTERY than the ones in this thread and are just used as an example!

i guess even though a burst isn't published for the sanyos here it can be assumed similar to another 10amp max cell.

Samsung doesn't seem to publish a burst graph, but samsung's site as well as LG's, show a smorgasbord of safety tests done including heat and shorting and everything passes with no fires. I think cells are getting safer.

I didn't get them thought and got the LG Hg2 3000mah with 20amp-ability for almost 100$ more. Now no one can roll their eyes at me

ordered 120 sanyo GAs, nicely wrapped parcel reached me a few days later, cells were 11/2015 and had a remaining charge of 3.62V. didnt measure capacity cause I was eager to build 2 batteries! ;)

thanks @ tumich!

tumich, do you think you'll have any more 29E cells in the future? Or any others with a similar price/Wh?

Nicely made but there is a bottleneck in connecting between series on the bottom. Current will be going through only 2strips..you have to beef them up :)

Just wondering if you have restocked the cells?

If not, it'd be great if you could update the first page.

zooz, I think Tumich does update the FIRST page quite frequently. He also replies to private messages quickly too.
You can view the updates as well, and see when Tumich was last online by clicking his nickname.

I tried to send a pm but am unsure if I did it correctly? I am interested in the Sanyo ga's but I am unsure of shipping to the USA. I am in Michigan. Please let me know if you received my pm. Thanks!

Hey tumich!

It would be great if you could update your first page, so we don't have to ask you all the time when the Sanyo NCR 18650GA are going to be available again!

Thank you
