[Q] About Liitokala 35A (NCR18650GA based) and other battery tips

Both a high discharge cell like an INR18650-30Q plus a good low-resistance quality switch (bypassed springs too) ensure maximum turbo for the O:) shortest time if heat is not a problem (higher discharge rate = lesser battery life).

Well, the concept of a cold night in Brasil is quite different than from the US/europe, so temperature is a problem, the flashlight will not be cooling that fast on the wind . The Concept 1 turbo is not meant to be on a lot, but 1 to 3 second bursts is kinda ridiculous. I checked ou the 30q and liked it better than the keeppower IMR I had in mind. Will not bypassing the sprints reduce the overall heat on a FET driver by reducing current or simply heat up other parts of the circuit?

Both in USA and EU there are very hot regions; where I live, for example.

Every bit of resistance counts in an unregulated flashlight. If you optimize the springs you'll reduce their resistance, which means the overall resistance gets reduced, resulting in higher current flow. What is more, as every bit drops an amount of voltage proportional to its resistance, you can understand reducing the resistance of a single piece will result in higher voltage drop in the remaining parts.

Recapping: less resistance = higher current = higher heat output.

I prefer regulated drivers. A powerful direct drive build needs careful assessment or you risk blowing things up.

Four weeks ago I searched at Gearbest for Button Top cells, because Banggood wasn’t able to deliver to Germany. Finally, I’ve ordered 4 pcs. of Liitokala Lii-35A and was hoping for GA’s. (https://www.gearbest.com/batteries/pp_677241.html?wid=21) I was planning to use them for the BLF Q8, because they supposed to be NCR18650GA and Gearbest sold them as “Button Top”. But- they are NOT (anymore?). The cells I’ve got early September are flat top, I can only use them in other lights. Fortunately, I was able to order at Banggood in the meantime and got 4 pcs. of 30Q with the transport box delivered. So I’m ready for the Q8, which is already shipped.

This site claims to be samsung INR18650-35e - LiitoKala Power CO.,LTD

I think yes, I have their flat top

The Samsung INR18650-35E is the greatest of the “35s”, though I would hardly qualify it as a “33” (1C discharge down to 2.8V).

Cheers ^:)

Thanks, my set is also 3300mAh
tested lii-35a is 3268mAh, 3287mAh, 3299mAh, 3345mAh (test with lii-500), resistance 25mR- 30mR

I just received my Lii-35A, and just like @Antenne posted, their top button is flush with the wrapping like the samsung 35E, and unlike images of the sanyo GA. Various pictures of the Lii-35A have them with the slightly raised button just like the GA, so I guess they switched it some point during productions, or maybe they are using a thicker isolating ring on the rewrap, who knows.

I would be nice to get a clarification from Liitokala. Nothing against the 35E, as they are very similar to the GA, but it would be nice to have a clear statement

Hmm. I’m also wondering about the LiitoKala Lii-35A, since this AliExpress seller also indicates that their Lii-35A is based on Sanyo NCR18650GA (similar to what GearBest indicates on their Lii-35A product page)

https://www.aliexpress.com/item/4PCS-100-Original-LiitoKala-Lii-35A-3-7V-3500mAh-NCR18650GA-10A-Discharging-Rechargeable-Batteries-For-Sanyo/32810182330.html

But as you mentioned, the LiitoKala official Lii-35A product page indicates it’s based on the Samsung INR18650-35E…

I bought from him, it is not NCR18650GA

That’s interesting, I don’t think I’ve seen any report on Liitokala batteries being fake…

Not “fake” per se, but apparently using a different food quality cell than the one advertised. I tested them on my fet+1 and my concept 1 and they behave like the GA and 35E are expected to

If they say it’s GA, it shall be GA, otherwise it’s fake.
I know 35E is a good cell and quite similar to GA, but nevertheless different. It’s also a cheaper one, so a good deal on GA may not be a good deal on 35E.

So I got 2 different answers from 2 different emails (both listed on liitokala website)

I think this confirms that they are using both cells to make their batteries as they are very similar in specs, and from the non-raised flat top on mine, I’m now sure they are 35Es. I just wish they were more clear on their AE shop in the item description

Be careful! On AE “official” LiitoKala store are selling fakes named NCR18650GA 10A. I bought a few, they are not Sanyo, Samsung or Panasonic, some noname china quality, max current with FET 4pc Oslons on freshly charged batteries 6-7A on different examples, where original Sanyo gives 8,5-9A.

China is now ripe with a new wave of inland battery OEMs. Now mix the following ingredients: a (much) lower comparable unit cost, little available information about them outside of their borders and a government and/or culture which openly endorses deceptive practices.

Already had a good deal of this stuff: Seems like I got a six-pack of counterfeit/fake Samsung ICR18650-30B cells :-/

There are fair dealers, of course, buy maybe with a more senseful pricing.

Cheers ^:)

I agree with Socal tiger and others. The Concept 1 should run on a Samsung 18650-30q or even slightly better the Sony 18650-VTC6. I have the Nitecore EC23 running a XHP-35 pretty hard and it runs noticeably brighter on a Sony VTC. This is true of my Skilhunt S3pro lights.
I have several Lii-32A and well as some 26650s and the are quality cells so I am not not knocking the Liitokalas. You just have to tailor the cell to the light.

I understand the Lii-35A is supposed to be Samsung INR18650-35E, but that AE “official” Liitokala store’s product description does indicate NCR18650GA. I’ve bought a pack of 4pcs hoping them to be INR18650-35E (my order has a tracking number already but no tracking update yet, so I’m not sure it it’s shipped or not…)
Hopefully it is the 35E, but if as you said it is just some unknown clone, I hope it has at least similar capacity as the 35E…

Any reason for you to not report these deceptive practices? Once the product is at your hands opening a dispute may take some time (if never done, maybe) but we need to prove AliExpress they're wrong in these matters, and quite unaware of actual vendor practices (or so it seems).

I swear to God I'll win my case.

Cheers ^:)

I have already opened dispute with photos and argumentation, and seller answered me “Hello! Our products are 100% genuine shot. Buyers use such pictures illustrate our products fake What persuasion? Buyers have carefully read our product details when buying products. Believe that our products are 100% genuine. Please do not take such pictures to arbitrarily stir up this malicious dispute. Thank you!”.
Now i am waiting for administration to solve our dispute.
