Obrigado MascaratumB. Smile I see these yellow stickers all the time and I wonder what the heck they complain about (manual in local language, CE sign, etc.). Never mind…


I guess you are right about the 20€. I guess those 25€ come from a minimum fee they need to charge you over here, so as long as it’s below that number they will not charge anything.


I found this about the upcoming regulations…


https://ec.europa.eu/taxation_customs/news/new-guidance-document-import-and-export-low-value-consignments_en


https://ec.europa.eu/taxation_customs/business/vat/modernising-vat-cross-border-ecommerce_en


“(…) The introduction of the import scheme goes hand in hand with the abolition of the current VAT exemption for goods in small consignment of a value of up to EUR 22. This is also in line with the commitment to apply the destination principle for VAT. (…)”


 


Thanks for the links L-P!! Thumbs Up

About the yellow stickers, I found this:
https://tompai.pro/ecommerce/goods-not-fulfilling-conditions-laid-articl...

Let’s see where this goes!

———————-

To not completely deviate this thread, I’d like to say that I left my T50 batteries charging over the night, 2 on the Astrolux BCs and 1 in the Vapcell Q1.

The Vapcell Q1 lighted green when the battery was at 4.14V. I left it a little more and it didn’t go upper than this.
The Astrolux lighted the 4 blues when the batteries were at 4.13V . Same thing as above!

The voltage was measured through a DMM.

I don’t have other 21700 charge to go upper than this, but being at 4.13/4.14V seems a good top using these chargers. Thumbs Up

OK, the T50’s are for real. They will replace my 40T’s. They tested at start in the neighborhood of 40T’s. Measured 24 amps on a slightly modded K1 SBT90.2, and 17.5 amps on a FT03 XHP50.2 with spring bypasses (GOLISI at 16.3 amps). Tested on a FT03 SST-40 at 9.35 amps, where the 40T tested 9.4 amps, and the 30T at 9.5 amps.

2× 40T arrived this week. Now I can try to compare them with a T50. Silly

Charged 1x T50 and 2× 40T to 4.203V, 4.203V and 4.205V.

T50 measured 20.6A on a Sofirn IF25A
40T measured 19.6A on a Sofirn IF25A
40T measured 19.58A on a Sofirn IF25A

Are 40T’s supposed to go a bit higher?

I wish my two T50 batteries were here already. Ordered November 21, shipped on November 25. Tracking has stopped in Amsterdam since mid of December. I know that batteries can take a bit longer due to customs procedures but more than one month is quite some time. Sad

 

Dennis, will there be any further update for the S4+ charger?

  • lower termination current (< 0.05A) in order to charge batteries to actual 4.20V (not 4.15-4.18V only)
  • off switch for the beep after charging is complete
  • wider slots to charge 4x 26650 batteries

Will you offer some (BLF) discount for the upcoming Chinese New Year sale? I am willing to spend some more bucks in your shop if the T50 becomes available again and if you were to offer a faster/more reliable shipping method to Germany. I have already contacted Vapcell's customer service but all I was told is to keep waiting and the window before I can raise a dispute was shifted by another 30 days.

Dennis - not sure if you've done so, but please send a pair of T50's to HKJ for testing when they arrive, if possible.

TimMc - your results may be a little better than mine, but there's always variances between lights and methods, etc. Also my 40T's are pretty lightly used, so the more heavier use, the lower a cell performs. I think I've seen the T50 do better than the 40T in some of my tests.

Sincerely apologize for keeping you waiting for the battery for too long

The normal delivery time is 2-4 weeks

I hope you can receive the goods as soon as possible

S4 + version has been upgraded

The full charge voltage is close to 4.20V, and if the low current charge is 250mA and 500mA, the cut-off current is changed from 100mA to 50mA

The market share of 26650 will gradually decrease, the share of 21700 batteries will gradually increase, and S4 + shell mold should not change. If the volume is too large and the weight is too large, the freight will be increased

The ring after charging is not expected to be cancelled. This is the first suggestion to be cancelled. Many users like this ring

BLF members have discounts when contacting customer service. The more styles they buy, the more discounts they get

If you want more discount activities, please contact customer service

I’m not in charge of Ali-express sales

thank you

HKJ received T50 samples a few weeks ago and is still waiting in line for testing

Please wait patiently for the test results Smile

Thanks a lot for your reply, Dennis. Coincidentally, the goods showed up in Frankfurt yesterday, so they should eventually arrive anytime soon. I could have walked the way from Frankfurt to Amsterdam back and forth and would have been 2x faster than this. Big Smile Anyway, not Vapcell's fault but maybe worth to note that some parcels can take an eternity to be processed.

Concerning the S4+ charger:

Good to see the termination current is down to 50mA. That should be in line with Miboxer's famous C4-12 charger. I agree with you that 26650 cells will slowly disappear from the market. Still, many of us here have/buy new flashlights with 26650 battery tubes and would really appreciate to have a four-bay capability for these big ones. Moreover, I always struggle to fiddling out batteries from those charging bays if they are too close to each other. Having more space between the bays will give you more convenience to put batteries in or out. Actually, I am surprised that I am the first to ask you for an option to turn off the alarm when charging is complete. I am quite sure you would give a lot of customers more peace of mind if they were able to turn off this sound.

Thank you very much for your advice

Now that the mold has been formed, there are no more buttons,

It can be considered that there will be a ring tone in automatic mode and no ring tone in manual mode

I don’t know. Is this OK?

Or is there a better solution?

thank you

Happy new year to you, too

Maybe Vapcell can offer an 8-bay charger based upon the upgraded S4+ charger. Four of these bays could then be used for 26650 batteries. I am pretty sure that there is demand for an "S8+" charger as we get so see some flashlights that need 8 cells (Lumintop GT series for example).

 

Having the ring/beep/buzzer tone in automatic mode only but not in manual mode is not really what I was hoping for. In most typical charging scenarios the user just want batteries topped up to 100% again, regardless of automatic or manual mode. The problem I see here is the noise that drives many men's wives into madness because they were just watching their favorite TV series or they were taking a nap on the couch*. Guess the look of their faces when the beep comes up again. Wink

So, a cheap straighforward-solution would be a (hidden) press-button-combination to turn the ring tone on and off. More sophisticated would be to see in the display if it's switched on or off (bell symbol?). I don't know, I just want to state some recommendations how to make a good charger a great charger.

 

* I did not mean to offend anyone or anyone's wife here. It's just a metaphorical illustration how things can be in people's living rooms. Silly

Thank you very much for your suggestion. We will communicate with software engineer and mould engineer about S4+

Are you sure there is a market for the charger with 8 slots for analyzing discharge and measuring capacity?

Is there a similar product in the current market?

Thanks

Dennis, maybe it's worth to start a separate (development) thread for a sophisticated 8-bay analyzing charger made by Vapcell. What do you think? This thread here should better remain your promotion and advertising thread. Wink

It's no secret that another manufacturer is doing a joint-development with a well-respected BLF member to launch a 4-bay analyzing charger to the market.

See all the information publicly available here:

https://budgetlightforum.com/node/67945

If I may add, the outcome of the feature list could be quite valuable to Vapcell, too. Lots of great ideas and thoughts that would be reasonable features in a battery charger.

If you are really interested to fulfill our flashoholics dreams, I would suggest to have some frequent mutual open communication with BLF, so we can talk about what can and cannot be realized and what milestones might be reasonable in terms of designing, testing and launching the new product. For instance, thorough testing will be a crucial point and so it might be a good idea to send some samples to skilled electrician experts like Henrik Jensen (HKJ) or BlueSwordM.

So, coming back to your question if there is such a device on the market yet: No, there is not actually. There are some nice 8-slot chargers but they all lack those great features that enthusiasts, battery experts and flashoholics have only found in some few 4-slot chargers like SkyRC's MC3000, Vapcell's S4+ or OPUS chargers. And still, even those few chargers deserve some minor improvements to become great.

 

Here's a list (not complete) of popular 8-slot chargers:

Could the buzzer be turned off and on when the backlight is turned off and on?

E.g.
Press DISPLAY to change slots.
Hold DISPLAY for 5 seconds to turn the backlight off and disable the buzzer.
Hold DISPLAY for 5 seconds to turn the backlight on and enable the buzzer.

Folks, bear with me in this question, that is sounding too absurd for myself, but, you know, I need to clarify myself.

The new Vapcell 18500 M12 1200mah 10A Li Ion, wasn’t tested yet, but I would like to know, theoretically:
having the same capacity as an Aspire 18350 (between 1100-1200mAh), both cells being rated to +10A, the Vapcell to 4.44Wh and the Aspire to 4.07Wh, will there be any substantial difference when pushing these cells to their max?

Using a flashlight with FET driver, triple emitters, and so on…a pocket rocket! Will there be substantial differences?

The first batch Aspires are a few years old already. The later batches were worse.
But this doesn’t let me answer your question, I don’t know.

I have some of the 1100mAh batch, which seem to be better than the 1300mAh teste by HKJ.
I guess I will place the question directly to HKJ, eventually.

I think the bigger difference would be in the long run assuming the composition is different. Maybe one maintains higher voltage in storage and/or has more charging lifecycles.

Believe it or not, my T50 (Samsung 50S) order has arrived after 66 days (about 40 days "vanished" between NL and DE). It almost felt like Christmas opening the cardboard box. Big Smile

I did some measurements right away:

Resting voltage: 3.45V

Impedance: 9.5mOhm @ 1kHz AC via SM8124A

I noticed this battery - probably like all Samsung cells - has a slightly recessed positive flat top terminal.

Hi, I made some research but couldn’t figure out everything so if its possible I need some help,

I’m looking for a few batteries and I will use them with;

Mateminco MT01 XHP50.2 (Astrolux AE01)
Mateminco TK04 XHP50.2 (Astolux FT02s)

Many 21700 batteries in my mind now such as,

Vapcell T50 5000mah 20A/35A (samsung 50S) (seems like everyone loved that battery)
Samsung 40T (solid legendary)
Vapcell G40 4000mah (30A/45A) (no body talks about it, I couldn’t find information but sounds like very promising)
Vapcell F40 4000mah (25A/40A) (no body talks about it, I couldn’t find information)

These 2 seems perfect for lantern usage?

Samsung 50G (green,version 2)
Samsung 48X (green,version 2) (similar like 50G but 48X perfect for a long run. Good life time better for environment)

Also what I couldn’t understand is samsung 40T has 30A max continuous discharge but Vapcell T50 with 20A has almost same continuous power like 40T how is that possible?
Is T50 unrated or wrong rated?

(And also any thoughts for Vapcell G40 30A continuous will it be even better than samsung 40T and vapcell T50 ?)

Thank you so much for your time!

i know its probably not – but is there anywhere we can order these right now? even if only to get back order notifications?

Hi, I made some research but couldn’t figure out everything so if its possible I need some help,

I’m looking for a few batteries and I will use them with;

Mateminco MT01 XHP50.2 (Astrolux AE01)
Mateminco TK04 XHP50.2 (Astolux FT02s)

Many 21700 batteries in my mind now such as,

Vapcell T50 5000mah 20A/35A (samsung 50S) (seems like everyone loved that battery)
Samsung 40T (solid legendary)
Vapcell G40 4000mah (30A/45A) (no body talks about it, I couldn’t find information but sounds like very promising)
Vapcell F40 4000mah (25A/40A) (no body talks about it, I couldn’t find information)

These 2 seems perfect for lantern usage?

Samsung 50G (green,version 2)
Samsung 48X (green,version 2) (similar like 50G but 48X perfect for a long run. Good life time better for environment)

Also what I couldn’t understand is samsung 40T has 30A max continuous discharge but Vapcell T50 with 20A has almost same continuous power like 40T how is that possible?
Is T50 unrated or wrong rated?

(And also any thoughts for Vapcell G40 30A continuous will it be even better than samsung 40T and vapcell T50 ?)

Thank you so much for your time!

Just giving my thoughts, but I’m no expert so just consider as reference..

I’ve gotten a pair of Vapcell G40 4000mAh 21700 (white wrapper) — this does not appear to be the same battery as the Samsung 40T, it’s heavier (~74 grams vs ~68 grams for Samsung 40T), and G40 has a slightly wider diameter (I measure 21.3-21.4mm for G40 vs the 21.0-21.1mm for 40T). Also, the top design is different (both are “3-lobes” but the lobe design is different enough).

With that said, I can’t reliably test if G40 performs similar or better/worse than 40T. Using YR1030 AC IR meter, I noted that the G40 has AC IR ~8.2mOhms while a 40T has ~8.8mOhms, so the G40 has a wee bit lower AC IR… this isn’t enough to prove anything though. Both are quite low IR though.

With regards to the discharge rating, I wouldn’t exactly trust the rating of the rewrapper, but instead check for 3rd-party technical reviews (eg. from HKJ or Mooch); unfortunately I also haven’t found info about the G40 (or F40) from either HKJ/Mooch..

now regarding the battery to use on the FT02S and EA01 — these are what I think based on my experience with these 2 flashlights: – FT02S (quad XHP50.2 LEDs) can use a LOT of power (more than 20 Amps), so a (fully-charged) more “high-drain” or higher-discharge rating (real rating by discharge graph by 3rd-party reviewers like HKJ) battery could give it the most brightness (in this case, a 30T theoretically could give a bit more power than 40T, which gives a bit more power than the T50). Although in real life, temperature control and other factors may make the difference small, but the capacity (runtime) should be there.. (higher capacity should have a bit longer runtime).

- EA01 (single XHP50.2) can also use a lot of power (a bit less than 20Amps), but most of the good 21700 batteries will probably just have a nearly similar effect. I would suggest a T50, but maybe another good 21700 battery like the G50 likely won’t be too different in performance compared to the T50.

Thank you very much for your support to vapcell

The power performance of G40 is similar to that of Samsung 40t, but the capacity of G40 is higher, about 4100mah

My MF01 mini could do with a K64. Wonder if the high capacity affects the lifespan of the cell.
