Thumbs up again…
these cells aren't available anywhere. Great specs but just unreachable
yeah, does anyone have a lead on when they will be available?
Thank you, HKJ 
now we just need some stock 
+100
So this is a rewrapped Samsung INR21700-50S, doesn't it?
20A continuous? Seriously? According to HKJ's graph, the cell overheats a bit before full discharge with cut-off at +50°C (this is equal to 75°C with 25°C ambient temperature). Typical maximum allowed cell temperature is 80°C, so… a bit tight, imho.
I see there's been an overall improvement in discharge performance, this is great as it means less heat or energy lost in the batteries as the current flows. However, how about energy density? They better get on it now that there's barely any oil to extract… O:)
Anybody know where to buy one of these cells? They seem to be the best battery that compromises between capacity and high discharge rate.
Nope, nowhere reliable.
Damn… any good alternatives worth considering?
If you need capacity, 50G, Molicel M50 or even sofirn’s 5000mA 21700s if you want cheap prices and decent performance seeing as how there’s a shortage of Samsung cells. 40T, Molicel P42A for higher drain. 30T for absolute max output with multi 50.2 fet lights
18650Canada has the 40T’s, but this T50 outperforms the 40T up to 15amps, which would suit majority of my lights…
Well I don’t see it being available in the next 3 months, maybe we’ll get lucky in 6 months or near the end of the year. There’s a major battery shortage going on right now. Check the typical American battery sellers. No stock of a lot of Samsung, LG, Sony cells.
Lets see if I can wait that long. Thanks for your input!

I noticed… Have they always been that expensive? Seems like a big premium to pay for the boost in performance over competitor batteries.
Yup. Nov 2020 2 pieces, AU$ 35.22.
Today, 4 pieces, AU$ 93.34 though I have asked for a BLF discount.
Do you know how much Vapcell does really pay for these cells? Also, do you know of any other place to buy them?
Particularly in these matters their strategy is to hoard and hog the product, and then place over it the price sticker they like. Of course it's not exactly like this, but they do feed out of your addictions. Are you addicted to having to buy the latest whatever, just because it @#$% extra performance which in practice you may not even notice without a measurement device or at all? Do you really need such a thing?
It's been years since I don't see any higher energy density technology. Comparing, for example, the Samsung 35E versus the muuuch newer 50G, there's absolutely no energy density versus mass improvement. What are they waiting for? Are they waiting for… Christmas? :-D
Long ago I heard in the grapevine that the oil wells were drying. And of course, they're dry. There were huge amounts of oil reserves, this is the reason things work. The Covid-19 farce is in part concealing this fact. But the clock is ticking. Do you think the cars of the future are going to be powered with this energy density lackluster battery technology? I know they can, they're selling you the extraordinary performance of electric motors to sell the new electric cars. But if we are to speak about their mileage or range, this cannot hide the obvious fact: it sucks. But well, this is another story…
This is a big increase. I paid $24/pair + tax back in November ($22/pair in October), now the same pair is $36 + tax, so 50% bump.
I'm out at this price. There's not even much of a discount with qty up to 10. They have to do better than this.
If it is Samsung cell inside, it will not go lower soon - nkon almost doubled Samsung prices in EU since end 2020…I guess Samsung and the other major brands benefit the boom of the EV.
