Re: CHEAP ORYGINAL CELLS 18650 3500mAh
LI-ON's 18650 are safe i have cut them in half put them in fire blown holes in them when spot welding them, about 30+ cells i have busted made by Panasonic pf's Sony vt4/5 Samsung29e 30q's 25r etc.. and have never seen one explode! or start a fire but i have stabbed LI-POs and and they have burst into flames.. Just look at them Panasonic Tesla cells!

Future plan for 20700B cells ?
Or just 18650 forever ?

Energy density of 20700 seems worse than the 18650's at the moment.
Re: CHEAP NEW ORYGINAL CELLS 18650 SANYO GA 3500MAH
Is there anyone in Toronto/Mississauga,Canada area willing to make me a complete battery pack 36v, ready to use with these sanyo cells?
thx
thx

Lowest lifespan of the appropriate batteries available. Consider another choice or accept a shorter lifespan.He's had better cells available and I'm hoping soon...
Thanks Justin_le we're here thanks to you. All the best to the mods for their tireless work keeping it on an even keel.
Re: CHEAP NEW ORYGINAL CELLS 18650 SANYO GA 3500MAH
Why do you think that have lowest lifespan? Depends on discharge rate like all cells. Maybe Panasonic's PF have better life span due to Fe in chemistry but doesn't have 3500mAh

Re: CHEAP NEW ORYGINAL CELLS 18650 SANYO GA 3500MAH
@tomjasz I have bought these cells from Tumich last year. I put one in accelerated testing 4.01 to 2.8V /6A. After 1100 cycles it was still giving >2800mAh under manufacturer test conditions.
And in real life, my commuting ebike that has seen approx 60 cycles in a year still outputs 95% of its original usable capacity.
These cells are good for ebike use as long as you don't charge them fast and dont need the high current. Because their true Achille's heel is that the internal resistance increases a lot with cycling. The capacity fade is totally acceptable.
I would only rate the 18650BM as superior in terms of cycle life.

YIKES!! Incredible prices on some real workhorse cells. My 22P 36V packs and 29E 48V packs are some of the most durable I have. Not high power but perfect for 15-20A applications. I wish I needed cells. These should not last long! NICE!!!

I use Sanyo GA 3500 in electric scooter E-ton/Matra e-Mo+ and they are very good.
Lot of tests on Internet to confirm that : among the bests, no hesitation !

OK Tomjasz : can you share data and links about shorter cycle life for Sanyo Ga 3500 please ?

Lots of anecdotal posts referring to sag and heat when run at rated amps. Suggested by many power users that 5A is a better rating for longer service. There have been many discussion on ES FB. Obviously your mileage is different. but many users pushing 40A+ controllers are suggesting lots of sag and shorter cycle life!
I think a battery should be chosen on specific application not one battery for all.

Re: CHEAP NEW ORYGINAL CELLS LI-ION 18650 FROM 1,09$ 2200-3500mAh!
What's the verdict on the Panasonic NCR 18650A cells? Much cheaper than the GA cells.
Looking for 14S4P at 20A max just for daily commute small light pack, so 5A per cell. These NCR18650A look good, but are they old?

5A per cells cont discharge for 18650A could be little too much.opperpanter wrote: ↑Mar 02 2018 1:03pmWhat's the verdict on the Panasonic NCR 18650A cells? Much cheaper than the GA cells.

I think it's going to be 10-15A continuous, 20A max. So 2,5A-3,75A per cell cont.tumich wrote: ↑Mar 02 2018 6:44pm5A per cells cont discharge for 18650A could be little too much.opperpanter wrote: ↑Mar 02 2018 1:03pmWhat's the verdict on the Panasonic NCR 18650A cells?

Can anyone tell me how long these usually take to arrive in USA/FL? Looking for a couple hundred for misc projects.

Hi Tumich / All
bought 96 18650GA cells a couple of months ago and just wanted to say thanks for it all going well.
Tested all the cells and each one is 3.49 or 3.50v !
Well packaged. And Tunich was very straight forward to deal with.
Keep up the good work. And Im really happy getting the 18650GA cells - perfect for what I need and I could not have done without these prices here in Europe.
Cheers - Allan

Re: CHEAP NEW ORYGINAL CELLS 18650 SANYO GA 3500MAH
So he gets different batteries over time?
I need something like 30q or 25r or around 15-20a discharge, were there batteries like this before on here?
Re: CHEAP NEW ORYGINAL CELLS 18650 SANYO GA 3500MAH
Yeah, often different cells, but 30q and 25r not as yet. Highest discharge cells he's had have been 10a constant, as far as i can remember. He mY have had some sony cells of higher at some point.Acido wrote: ↑Apr 01 2018 4:48pmSo he gets different batteries over time?
