Where to get high-capacitry bang-per-buck 18650 batteries in bulk?

Looking at the likes of Panasonic 18650NCR 3.4aH OR 3.6Ah or LG 4.0Ah. Each battery can store roughly 10Wh of energy.

And I want of the order of 100 of them maybe more. This is for a mobile general purpose power supply project.

Oops, I thought you meant "bulk". I was going to suggest you can get around 5000 - 8000 18650s with about 3150 mAh each cheaply by buying a Tesla replacement battery pack. :-)

Yeah little bulk: 100s not 1000s

Did some research into this last year, found few companies worth bothering with.

This company have bulk LG MJ1 3500mAh cells, that aren't fakes.

Some other companies have issues with shipping to Australia, so aren't worth the trouble.

Not exactly what you are asking for, but what about these modules? Would save a ton of work...

Not sure whether "frexible pricing" is a good thing or not...

[elektrinis]

Flexible part comes from discounts for advertising. The company works with electric formulas etc, where they can offer big discounts as part of sponsorship package.

That would be nice. Theirs, however, is "frexible".

Thanks for this tip. I did buy one cell for two times this price (three including shipping), just to be sure I would have a good quality from a reliable source.

Not exactly what you are asking about, but might do just as well and save you a load of money.

I don't have any immediate need or projects but been looking for fun too and it seems there arn't that many sources.  Hopefully that will change as there does seem to be a bigger interest in these in general.  Amazon seems to be an "ok" source but it's really hard to tell what you're getting.  Lot of fakes and perhaps some of the non fakes might be overpriced, hard to really know.  The going price seems to be about $10/cell for a premium type but perhaps that is actually more than one should pay, really not sure.

I've just ordered 30 NCR18650GA for about 6.40$ per cell on ebay germany, which I bet the seller imported for 4-5$ from the factory by buying via alibaba or the like. At 100, why not just order them from the factory yourself?
