Ok,,,,,,,,,,,,,,,I started another test for BOTH batteries on February 9th, 2017.

BOTH BATTERIES CAME OFF THE CHARGER @
4.20V.

AFTER RESTING FOR 1 WEEK:

BATTERY "A" WAS @ 4.18V


BATTERY "B" WAS @ 4.17V


These are certainly Acceptable and Normal voltages 1 Week after being charged!:thumbsup:

I am not sure why my first test had the voltage DROP from 4.20V TO 4.14V IN 8 HOURS!:thinking:

I believe my cells are Fine, they are real and they should perform and last like my other VTC cells have!

That minor drop is totally normal and expected. I let my Sony laptop pulls sit for a month, IIRC and they didn't drop but a couple of points over that time--charger: 4.17v, day later: 4.15v, one month: 4.14v, so I felt comfortable using them at say... a 1A current, or less.

Quick question for you - I ordered a Emisar D4vn quad thrower R from Vinh, and I read that it can pull slightly above 20A on max. I only plan on doing this for short bursts (15-30 seconds) to keep the heat down.

Would this be an appropriate battery to use in this light?

The battery can do it, but it is a very high load for it.

Vinh recommends the VTC5A for BOTH the D1vn[I am getting] and the D4vn.

Look at HKJ voltage curve comparing the VTC6 and VTC5A,,,,,,You will see that the VTC5A is better,especially in the beginning. VTC5A is able to deliver more amps.

If your concerned about the run time difference. The VTC6 has 16.66% more run time according to BOTH capacity tests of the VTC5A and VTC6, at 1 amp.

2480mAh for VTC5A and 2976mAh for the VTC6

I actually broke it down to the minutes at a specific point in each batteries run time. Just an estimate.

Thanks guys. I'll be going with the VTC5A for this one.

Sorry, last question - do you think the d4 has enough protection built in (low voltage cutoff, temp regulation, etc.) to safely use the VTC5A or VTC6?

I would ask Vinh that question. He recommends the battery on his website.

I personally do run time tests with each new battery and light that I get. Been doing it for years. Then I know how long I can use it and never worry about draining it too much.Because of that I have actually guessed the voltages many times.

Here is your light on Vinh's website.

I know Vinh sells the VTC5A. You can get it $3 cheaper from my Hometown dealer,a great place w/ the best customer service around.I am fortunate in that I live 1.5 miles away. I just picked up 2 X VTC5A for my D1vn. These batteries are fresh like all of his[wholesale distributor]. Born on Date is June 13, 2017.:thumbsup:

I went with 5A because HKJ reviews showed it would not get dangerously hot at 20+ amps. Most batteries, including VTC6, get too hot at 20+ amps.

Do you think VTC6 are adapted in a SC600FD MkIII+? Or are there more appropriate (technically-wise or cost-wise) cells for this light?

I'll second ven.

There's always a bit of a subjective side to declaring a battery "the best" for any given task, but the VTC6 is certainly one of the best.

My own experience has also been good with VTC6 in an SC600w.

Yes, although maybe it could be argued its a little overkill for the ZL, once the voltage drops down, it will enable you to hold higher modes(H1) for longer! . Less voltage sag compared to the sanyo GA ZL recommends for their light.

And the capacity difference between the. VTC6 and GA is not NEARLY as great as the numbers suggest.

Would the US18650VT6 be acceptable in the single cell Armytek Viking Pro v3 XP-L? It seems the output would be within reason?

Thank you HKJ. I have been reading your reviews for 6 or 7 years. they are very helpful, I like the VTC6, but I like the VTC5A better!

My cousin modified a few of my lights and I have used these great Sony batteries in them.

In terms of flashlight use, thinking the difference between these various fine batteries is not detectable with the human eye, nor would we be able to sense a great difference in runtime, though it can be interesting to discuss.

Sony VTC6A has been tested:

https://www.e-cigarette-forum.com/t...s-vtc5a-estimated-2900-3000mah-20-25a.849291/

...The two samples of the VTC6A I tested easily outperformed the VTC6. While the VTC5A hit a tiny bit harder than the VTC6A at the start of the discharge the VTC6A outperformed the VTC5A for the rest of it, especially at higher current levels. This is a great battery....

...The VTC6A's I tested delivered 2892mAh and 3008mAh at 0.5A. This is a larger than typical cell-to-cell variation for Sony cells. I don't know why....
