Review request for HKJ [Rechargeable Batteries]

HKJ,

I am looking for 14500 high drain (3A) unprotected cells.
Sanyo UR14500P has good capacity, but struggles above 1A.
Any other cell you can recommend?

Maybe these HIBATT IMR14500 (700mAh 10A)? Sounds good, maybe you can test them.

Those HICRAP HIBATT IMR14500s seem to be another rewrapping of the ubiquitous Trustfire IMR14500s:

Hope this helps.

Cheers ^:)

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

It does help, thanks.
Any non-crap unprotected 14500 you can recommend?

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.

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.

Cheers ^:)

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.

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.

Cheers ^:)

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)

Cheers ^:)

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…).

There are even Li-Io 9V batteries:

But i would like to know how well the 270mAh NiMh perform.

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

Seems very well done and the length adjustment is easy.
