I am fairly low on small batteries (i.e. << 2800mAh) and will probably buy some to test soon.

Great! Please try to find some good 14500 cells.

I will probably look at the usual Chinese shops, but I will also look in this thread for ideas.

Any non-crap unprotected 14500 you can recommend?

Well, trying not to be excessively picky, those TrustFire IMR14500s work well in fact.

I have a pair which I've just homemade freehand internal resistance tested, though I can't guarantee these figures to be 100% reliable because of the finicky seating of these tinies on my charger: 82 & 80mΩ. My bet is they can handle 5A continuous very well thus.

It's wide flat-top protrudes a smidgeon, so they can be set in series without problems.

Thanks. What about claimed capacity? Remotely close to real life?

I haven't tested that myself. They are reported to achieve a slightly lower capacity figure (≈10%) than claimed. It seems you won't find a much better product than this one in this category.

For a while now the EFEST IMR and WindyFire IMR are generally considered the best performing 14500 cells around, maybe slight advantage to the WindyFire's, plus cheap for flat or button top at $3 each. Richard at MtnE sells both, not sure where to buy overseas.

HKJ's review here for the WindyFire: http://lygte-info.dk/review/batteries2012/Windyfire%20IMR14500%20600mAh%20(Red)%20UK.html

It’s strange, but has nobody asked for LiitoKala 26650 review?

Yes - I'd like to request reviews for the LiitoKala 26650 (or as sold under other brand names), and a reminder for the LG HG2.

I realize the LG HG2 was originally requested in post #4, June 2015.

I think I made the request for the LiitoKala 26650-50As some time ago. HKJ said they weren't on his list… 

Besides Mooch at the E-Cigarette Forum, I don't know of any other willing and/or capable of doing a decent review of 'em. My bet is, unless HKJ changes his review policy (which may be mediated), Mooch is our only chance for now.

My list is running fairly low, this means I am looking for new batteries to review.

These bad boys i bought mine from Fasttech so damn cheap and they perform well just a tad under my AW 14500 IMR cells but so much cheaper. i think they are the same as the Fandyfire 14500?

Well, these aren't exactly the same I have lying around, maybe some sort of cheaper button-top counterpart.

This is the real deal @ FT: TrustFire IMR14500 3.7V 700mAh Rechargeable Li-ion Battery (2-Pack)

Since LiitoKala are available on GB/BG and they do cooperate with HKJ for reviews, I don't see anything insurmountable here.

I would like to see reviews on 9 volt batteries.
I have been using a 9v nimh duracell ultra for some months.
Works fine but it requires a special charger. Luckily I moved from the classical cheap 9v charger that took a day to charge, and I am using an imax B6 at 0.1A. Now the charging is quicker and I get more runtime from the instrument.

I am getting a li-ion rechargeable 9v battery, a zenter s19 9v, that should allow me to have a lot more runtime and won’t require any special charger. In the eventual reviews, I’d like to know, if possible, if this model, or any other li ion rechargeable one, can be recharged while used.

EDIT: also, I’d like to know which nimh 9v battery tipe is best for which application (8.4, 9.6, 10.8…).

All my reviews, in italian and english, here: Lumenreviews.com

Not a battery, but there’s an updated version of the battery fixture you also use.

https://www.fasttech.com/products/0/10024652/5339401-bf-2a-4-wire-batter...

Seems very well done and the length adjustment is easy.

I have been ordering some 9V batteries from Conrad.
And thanks for the link to the updated battery fixture. I do not know if I will review it, but I have ordered some for my own use. I do not suppose they will melt as easily Big Smile

It would be very useful if someone did a good review and teardown of the popular 9V Li-ions: EBL and Soshine. I don’t recall seeing any in-depth reviews yet. There have been many requests about such but very little feedback. It would be interesting to know which if any include balancing, and how quickly they degenerate without balancing, etc.

I will include some LiIon in my 9V reviews. Teardowns will not be included in the reviews, but may be done at a later date.
I doubt the 9V with two cells in series has balancing, but I have not going to do a few months of cycle tests.

Good to hear you’ll be doing some testing. I thought you had things so automated that you could easily do some limited cycle testing. Probably after 20-40 cycles one should be able to start making some predictions.

Cycle testing is easy enough to do, but it would require an extra DMM connected between the two cells to really see any unbalance and it takes a lot of time to cycle. 100 cycles on a 18650 cell is about 1 month testing time when keeping current reasonable (1A).

Whoa da -- it's here! The 20700. Didn't realize. so 12A max continuous. The capacity is look'n. Guess resistance is better than GA's, not as low as a 30Q, based on it's max 12A rating. We'll see if this makes a good percentage of our lights obsolete.

Meanwhile, in the thirld world of batteries, stars like LiitoKala 26650-50A(B) seem unnoticed by the @#$%ple…
Am I the only one who is seeing an incredible amount of fuss about a new freakin' cell format? Could care less about something I don't a really have a use for. 

Of course, just an opinion.

Now I just have to live up to the rumor (At least by some CPF readers).
Who will pay for the batteries?
Who will pay me for the review?

Sorry, I am just a bit disappointed about that post on CPF (Link do not work)
