Sony VTC6A 3000mah,will you choose it?

I’d be quite interested if HKJ tests show that it has a high drain performance at least equal to vtc5A. Then it’d be better because of the higher capacity.

So I’ll wait for his tests. Of course one must find a vendor that ships to his country, which is becoming increasingly difficult…

Interested depending on price and shipping

Is there a point where some of these high drain batteries might provide too much amperage for lights that use direct drive FETs?

Yes.
You’ll need a REAL driver.

Well yes and no, depending on configuration of host, emitters, thermal path with cooling etc.
Due to new generation of emitters that have forward voltage less than 3.5V at 6A or more you will probably need current regulated driver. Member led4power have great solutions with his regulated linear constant current drivers with a configurable option of direct drive on “Turbo” for 3V emitters and in near future 6v and 12V as well.
For more information search for “LD-4 CC linear drivers”.

Yes. I will choose vtc6a if the battery spec is same as vtc5a… extra mah.

So it seems between VTC6 and VTC5A in both IR and capacity; at very high currents a batter tradeoff than either of them. Definitely a very good cell, but since I have both VTC5A and VTC6, I see no need for this one. Especially that I don’t have any light that would draw 20A / cell. Let alone one that would do so continuously.

If I could afford only 1 high-current cell type, this would most likely be VTC6A.
If I was not constrained by budget, I would get VTC6 + VTC6A + VTC5A.
Well, I’m between and what I have now seems the best choice.

If they are not totally overpriced and locally available I will buy 4 cells to try them out.

Where do you buy these?

I want to buy this vtc6a

Any news?

VTC5D maybe?

PRELIMINARY Bench Test Results: Sony VTC5D 18650...around 25A, 2700mAh-2800mAh, beats VTC5A @ E-CigaretteForums

Cheers :-)

How much is it? if is cheap , i will choose it :smiley:

Cheap and Sony usually aren't synonymous, imho.

Cheers :-)

Any idea if these will ever be purchasable? I’ve been holding off buying the VTC6 for awhile in anticipation of these.

Does this new Vapcell look like a rewrapped VTC6A?

A 21700 cell and 4000mah. Looks similar to the Samsung 40T.

VTC6A is 3000 mAh, so this is more likely VTC6.

There are two models of VTC6A at Sony / Murata, the first is a 18650 cell having the exact model name US18650VTC6A and the second is a cell 21700 (same technology and technicality as his little sister in 18650 but deployed on a larger volume, the 21700 format, which consequently increases its capacity and its performances) having exact model designation US21700VTC6A. The same portage has also been made for the US18650VC7 (18650 / 3500mAh / 8A continuous), which has the exact model designation US21700VC7, it is a cell 21700 (as the name suggests) which has a nominal capacity of 5000mAh and a continuous discharge current of 10A, it was necessary that Sony / Murata has a competitor against the Samsung 50E and 50G as well as against the LG M50 and of course the Panasonic / SANYO NCR21700A (yes, that’s his model name, this is the only 21700 from SANYO, it is a 5000mAh cell and 15A continuous discharge).

Another thing, the rewrap of the Sony US18650VTC6A by Vapcell is the one he calls “Vapcell INR18650 3000mAh 25A Max continuous discharge” and its wrap is purple metallic. Here is the link on their website: http://www.vapcelltech.com/index.php/Show/index/cid/17/id/31.html

I have their rewrap VTC6A, bought in February 2018, they are very good performers.
