What is the best high capacity 18650 battery?

Yeah, you are right about lllum. Apparently they haven’t changed their shipping fees to reflect the new rules. (according to liionWholesale here). Get um while you can .

All three cells are good… you will use them accordingly to your flashlight needs.

Example

Blf gt xhp35… it doesnt matter. as long as 10a or above are fine… lg mj1 is fine.

Some xhp70.2 might need samsung 30q, or higher end sony cells.

Without HKJ and Mooch, we’d be in a poorer place.

And if anyone ever finds themselves within proximity of Illumn in California, I’d urge you to stop by the B&M store (weekdays only), even if just passing by like I did. Those guys are laid back and very much enthusiasts, and have a tonne of stuff on display.

Better leave your credit card in the car, though, if you can’t resist temptation.

How about the LG INR18650-M36 3600mAh - 10A?

As I said before, the manufacturer ratings on the cells are BS and don’t represent real world performance and usable currents like in a flashlight. Always look at reliable test data from people like HKJ

Just wondering.
Here in AUST. we buy most avail items from China, Eastern country’s. Incl battery’s.
We pay no freight charges. unless a coupla $$’s for tracking on exxy torches etc.

IE 4 x 30Q del to door. $18.60AUD. BLF L6 Del $88.00 AUD.
full prices I paid, not coupons.
Lion seems to be US/Canada only. NO access to AUST.

I never buy anything from US anymore. their freight even for letter size is ridiculous.
Your US/Canada would have to be politics. Yes.

We used to send presents to a coupla NC Neices and son.
Freight was always 3 or 4 times more than cost of parcels.
Nowadays. just transfer some cash.

Getting harder for us Canadians as well. Very few US companies have reasonable shipping to Canada anymore. That is why I purchased many batteries from Banggood to stock up. Got more than I need right now and glad I did. Illumn in the US is still the best price to send batteries to Canada but you still end up paying about 50% or more than buying the same batteries from Banggood. Right now BG does not ship to Canada again.

The cost being so high for ordering cells inside of Canada is because the shipping permits for shipping lithium ion are prohibitively expensive, being about 10 000$US, and because the regulations in Canada are even tighter than the ones in the US.

That is a recipe for a price and competition trap: since it costs so much to get a permit, and even if you can pay, that is hard to get, there are very few players selling lithium ion cells, and there being little competition, prices are sky high for lithium ion cells sold separately.

TLDR: I hate the Samsung Galaxy Note 7 for making shipping 18650s that are safer extremely hard and expensive to do so.

Local vape shops may carry 18650. That market is much larger than flashlights.

They do… at insane prices.

i disagree with you
the rating is not BS, it’s all true, all their figures is true and measured, it’s not BS like ultrafire 9800mah
“don’t represent real world performance ”, just to remind you that real world doesn’t only have flashlight, there are other low power devices that run on 18650 cell, even some flashlights have very low discharging current, not all flashlight need more than 1A

I agree mrheosuper, I think the few reputable brands are pretty honest with their claimed ratings. :+1: . Sony, Sanyo, Samsung, LG, & Panasonic… to name five.

And whoever makes the 26650 LittoKala 5000 mAh.

But, my ‘BLF Brother’; it is hard to believe that you only mention the 9800mah TrustFire 18650 when it has clearly been surpassed as ’the latest & greatest’!!

See picture below & get with the program my friend. :wink: . :smiley: :smiley: :smiley: :smiley: :smiley: :smiley:

Dang, looks like I need to “get with the program” also!! :smiley: :smiley: :smiley: :smiley: :smiley:

Sign me up for a couple dozen of those…. :wink:

This pic is a favorite of mine.

:confounded:

There is no sand for the "right weight"?... I'm disappointed))))))))

Still the best pic out there. Should be posted on every battery thread.

Clearly you need to do some research and look at tests of the cells.
Maybe then you can explain why some 3600mAh rated cell magically performs worse than a different brand 3400 or 3500mAh rated cell.

It would be ridiculous for me to say: “The SYNIOSBEAM’s output specs are complete BS. It’s expensive and huge, and it doesn’t even light up my back yard as well as the modded $20 BLF A6 I carry in my back pocket.” Right?

That’s pretty much what you are saying about battery ratings.

Manufacturers claims are based on measurements made under specified conditions. They almost certainly go to some lengths to make sure that their measurements are repeatable over short and long periods with regular, traceable calibration of their equipment. I don’t know what their sample size is, but I am sure it is more than a couple of cells.

HJKs tests are careful, he may not be controlling conditions are carefully as a manufacturer might, but I don’t think people should have any reasons to doubt his results. His results often differ from those in manufacturer datasheets not because their ratings are bogus, or that his testing is more or less careful than their; they differ because he tests to a different standard, and one more tailored to flashlight use. He also rarely/never, tests more than two cells, and the cells he tests are often of uncertain provenance.

Two of the major components of every flashlight, the emitter and the battery, are not designed and specified for the flashlight market. That makes it particularly important to understand the assumptions underlying the manufacturer specs. Independent tests to flashlight-oriented standards are very helpful in their own right, and for better understanding the mfg provided secs. Calling the manufacturer provided specs “BS” both cultivates ignorance, and makes the independent tests less useful.
