Sofirn Aliexpress Store added some stock in US, Poland and Russian

Yes, in sofirn official store the 26650 5C 25A battery on sale

I've solder blob'd a bunch of 26650 flat tops, mostly LK's. Works great, and typically you only need one with a solder blob for a 2 cell lights. I've been running my L6's this way. Also the solder is lower resistance than typical button tops, though the quality of button tops vary greatly.

I noticed the Sofirn Q8 is advertised at $40.59 but when selected it shows $41.99.

How to pay with Paypal on Aliexpress, I only have Visa, Webmoney and Wire Transfer for options ? No PP…

Can anyone confirm those are the high drain button tops?

By credit card is fine

yes, button top correct

sorry. i am not sure what happened, may different between APP and PC, and could use a coupon when ordering

I put the Q8 in my cart last night @ 40.59; today the cart price shows 41.99, same as product page.
Your listing on this thread still shows 40.59- someone needs to correct.

I’m unable to order bare batteries from Sofirn (no shipping method for bare batteries), so I ordered the SP33 with 26650 “bundle kit” instead at 2 different occasions to get hold of the Sofirn 26650 battery.

I notice that the 2 26650s have similar wrapping, but have slight difference physically. I wonder if one of them might be the so-called “high-drain” type.

I have yet to do a capacity test of the 2 batteries. But using YR1030 resistance tester. The more protruded 26650 (has smaller vent-holes, bottom is not completely flat) measured 41.7mOhms (AC IR) at 3.90v whereas the flatter 26650 (completely flat bottom) measures AC IR of 13.7mOhms at 3.90v.

One weighs 92.5grams while the other weighs 93.0grams (basically very similar weight, might even just be sample variance)

I suppose the 13.7mOhms version is the high-drain type?

I doubt it. The HD batteries have a button top added on and have not started shipping yet. They are also rated at 5000mah.

Do you have a clamp style ammeter to measure them in a FET style light?

As far as I know, Sofirn uses different generic batteries in 26650. Some measure closer to 5500mah and are labeled as such. Others measure closer to 5000mah and are labeled as such.

It is not possible to pay with Pay Pal, as I can see it is only for USA and UK customers.

Two weeks since I ordered 26650 batteries and no tracking updates. I wonder if a shipping label was printed for my order and pinned to a wall.

On the other hand, some other items I ordered around the same time seem to be somewhere over the pacific ocean.

Same here.
About my order, tracking does not work.

Well, my batteries arrived in the mail today… out of nowhere. Based on the IRs I’m seeing, I’m very skeptical of the 25A rating.
