Latest release Vapcell 21700 5600mah 12.5A battery

Obrigado MascaratumB. :-) 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 20ā‚¬. I guess those 25ā‚¬ 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/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!! :+1:

Letā€™s see where this goes!


To not completely deviate this thread, Iā€™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 didnā€™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 donā€™t have other 21700 charge to go upper than this, but being at 4.13/4.14V seems a good top using these chargers. :+1:

2x 40T arrived this week. Now I can try to compare them with a T50. :stuck_out_tongue:

Charged 1x T50 and 2x 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 40Tā€™s supposed to go a bit higher?

Are more T50ā€™s coming?

I only got 2 :frowning:

Very good test sharing :slight_smile:

Sell out nowļ¼Œplease wait if u want more :cry:

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. :-(

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

Iā€™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 :slight_smile:

Thanx Dennis! I'll try to politely give HKJ a nudge on these

Just posted in his review request thread: https://budgetlightforum.com/t/-/34262

A switch to turn the ring sound off and on would be nice. :+1:

Thanks for clarifying! :slight_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. :-D 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.

Some member even tried to remove the buzzer...

Anyway, č°¢č°¢ for listening to our thoughts here on BLF!

节ꗄåæ«ä¹ :-)

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 donā€™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. ;-)

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. :-P

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. ;-)

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:

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.

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.

EDIT: Iā€™ve already removed the buzzer. :stuck_out_tongue:

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, wasnā€™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 onā€¦a pocket rocket! Will there be substantial differences?
