I don’t think there is one best. The 3 you list are all good high capacity cells.

Those are all good. If I had to choose it would be….

  • 1. Sanyo GA’s
  • 2. LG MJ1’s
  • 3. Samsung 35E’s

That confirms Virisenox’s recommendation in the other post Thumbs Up thank you! I try to find the best price…

edit

I forget to ask 1 question about driver; I have just buy a M2X-UT olight with a extension tube to have 2×18650 battery power.

How to make the light become super hot rod Smile ?? is there a good driver recommended for this light so I can get more power to xpl-hi led?? Reflector is very nice and can throw very good, but people say can boost it…

sorry for asking stupid question but I don’t know very well electronic.

You can do one mod to boost it without replacing the driver, and that is bypassing a spring.

Steel is not a good conductor of electricity compared to copper.

In fact, on average, it has 5% the conductivity of copper.

Take 20AWG copper wire, solder it to the top of the spring, then around the spring, solder it to the bottom, and you are good.

Replacing the driver is going to be harder, so ask people to help. I can’t right now since I need to sleep. Ciao!

The highest capacity for 18650 is 3600mAh, not 3500

The list should look like this

  • Panasonic NCR18650G (impossible to buy)
  • LG INR18650M36 (3600mAh / 10A)
  • Samsung INR18650-36G (3600mAh / 10A)

There is no need to get too technical. Battery capacities vary based on load, temperature, etc… He just wants to buy some “good” ones. No Panny B, no old ones, Ultrafires, etc…

I consider the best batteries the high drain ones because I usually don’t run them down below 3.5v anyway. That extra capacity is lost on me, but I sure like the reduced voltage sag. Thumbs Up

18650G is not a 3600 mAh cell unless you over-discharge it to a silly level.
See this test:
https://lygte-info.dk/review/batteries2012/Evva%2018650%203600mAh%20(Black)%20UK.html
It is extremely close to 18650GA. In this test it shows higher IR (which may be due to protection) and exactly the same capacity. So really more like 3350 mAh. Actually we’ve seen some rewrappers (Klarus comes to mind) replacing 18650G with 18650GA in their lineup while retaining 3600 mAh marking.
https://lygte-info.dk/review/batteries2012/Common18650comparator.php
Compare discharge curves of 18650G and 18650GA at low amps, all the bumps line up.

Can’t speak about the others though.

Battery's capacity is defined in the IEC61960-2003 standard as the capacity at 0.2C discharge to the cut-off voltage (see datasheet) after being charged at the standard charge current (see datasheet) and left for 1-4hrs befor discharging. All this must be done at 25±5°C.

Of course we can charge and discharge at any current and measure the capacity as we want, but the nominal capacity according to the standard and mentioned by the manufacturers is the one i described above.

I haven't tested any of Gs so i have nothing to say about their actual capacity. Maybe Panasonic stopped its production due to such poor performance.

You get my point though, right? In real use you don’t get that exact 0.2C discharge, etc…

So in a flashlight the capacities vary.

MrGrun just wants to avoid any duds. All those cells mentioned above are about equal in real world use. Your not going to notice an extra 100mah. Wink

Of course you'll never feel that 100mAh in real life. But we can't measure a capacity "in real life" that's why we have standards with guides how to do that:) That's what i'm talkin' about:)

None of these BS manufacturer claim numbers are correct. Go look at a proper test done by HKJ and you will see the true capacity.

The 35E has the most mAh, there is no debate about that.

I will order several batteries end of July for me and my friend also. I just want to get the best value product. From the vote, majority say Sanyo is the best (made in Japan) I don’t know HKJ BS procedure testing, but I rather trust BLF users experience. I am just afraid to get fake Sanyo Flat Stare

Any recommendation for some trusted online Sanyo battery seller? (my friend stay in USA)

thank you

Get them from Liionwholesale:

https://liionwholesale.com/collections/batteries?page=2

I would get 4xSamsung 30Qs in high drain light scenarios, since they have lower internal resistance, and can lose less power due to heat, along with 4x NCR18650GA or LG MJ1.

Actuall HKJ is one of the best reviewer at here( and yup, he is “BLF users experience”)

You will not get any better “experience” than info from HKJ.

Here is a link to his site…. poke around & check it out. Wink

The GA keeps a slighly higher voltage than the 35E at medium currents, like 3A, typical of 1000 lm flashlights. I think the higher voltage and total power would be useful for the buck driver that the M2X-UT seems to have.

Still since both are very close I would buy the cheaper one.

Depends what you want.

NCR18650GA has a slightly higher max amperage than the 35E.

35E, however, has a slightly longer run time at lower outputs (<0.5A and below). They are about the same at 1A.

The MJ1’s are pretty similar but seems to be slightly worse.

LOL 

If you had a chance to have sex with Angelina Jolie would you do that or you'd prefer to ask Brad Pitt how she does in the bed?

Having all 4 cells in my hands and a good equipment i preferred to do my own tests at the same time in the same conditions, following the IEC61960-2003 standard rather than just sitting in the sofa and posting others' tests.

HKJ has inspired me a lot and i think not only me but also hundreds or even thousands of others. King regards to him from Russia!

In my opinion the Samsung 30Q (and LG HG2) are better than all of them because they also work when it’s cold outside. They also worksbetter in high-powered flashlights and can be charged more quickly. In addition to all of this they are very cheap. Sony cells are also good, but they usually cost much more.

The runtime of the 35E is higher than the NCR18650GA at ALL currents.
Go to the website to compare them at other loads.

It does have more voltage drop at higher currents like 5A, but that only changes the Wh not the mAh.
The MJ1 is definitely worse.

I’d still buy which ever was cheaper. 100 mah isn’t gonna make much difference unless your driving a led at 1 ma.
Differences in manufacturing and age could make up such a small difference. Same reason HKJ always test two batteries instead of just one.

The MJ1 is definitely worse.

In the case of a linear regulator it doesn’t matter (apart from the fact that it may fall out of regulation earlier), but if you have a buck or boost driver then Wh is what you care about. Higher input voltage means less current with DC-DC drivers.

I don't know but I've been hoarding batteries from Banggood every time they announce they can ship to Canada again.  For Liions shipping price, I could just drive across the border and pick up the batteries myself, go spend some money at Harbor Freight and Burger King and still come back with a few bucks in my pocket!

This was talked about in another thread. Apparently, liionwholesale is strictly obeying shipping rules from USPS, and it basically makes it cost-prohibitive to use them. So, they use UPS, which is

(1) Way more expensive, and

(2) You’re going to get burned with additional brokerage fees and taxes when your order arrives in Canada.

It makes ordering batteries from liionwholesale ridiculously expensive for Canadians. So, forget about buying from them.

Instead, I’ve placed a couple of battery orders from Illumn this year. They will use USPS. It costs $15 shipping, but I think that’s for any order size. You won’t have to pay additional fees and taxes when you get your order, either. Much less expensive than liionwholesale, and they’re genuine batteries and extremely well packaged. (Cells in plastic cases, inside a padded cardboard box, inside a bubble-wrap package.)

Anyway, I know liionwholesale gets a lot of kudos here, but I’m guessing that’s just from US customers. Oh, one other issue I have with them is that they won’t guarantee your order, and make you sign a waiver saying that any losses are your problem. What’s with that? They’re the only retailer I know that does that.
