True 35A continuous discharge 18650 battery??

Wondering if anyone has legit info on this thing??
Subohmcell 18650 35amp 2800 mAh Battery - Kidney Puncher

 

[shroomalistic]

looks promising, we need something new like this with vtc5 shortage

Isn't it the general trend with 18650's that the mAh goes down, as the amp limit goes up? 2800 and 35A would be quite impressive.

It also looks oddly like a Duracell, with that color scheme.

INR? Is that really the chemistry, if so that would lean me towards Samsung cells being under the wrapper...either way 2800mah/35A is impressive, I must do research now...

Edit: Hmmmm... SubOhmCell

Interesting test results. Their VTC5 curve does not jive with what Illumination Supply put out for 20A with their VTC5. Very high voltage drop in the beginning and low mAh. Does anyone know which of them are correct? I have no reason to doubt Illumination Supply, but I also don't know that they are correct.

If Illumination Supply data is correct, the VTC5 is the better battery in both less voltage drop and in more mAh. That jives with my gut feel here too, but that's just my opinion

The test graphs shown are based on pulse discharge 4s/60s rest. Need to see a 35A continuous discharge graph to see if this new subohmcell is really what they say.

I'm far from being any kind of battery expert but I have a hard time believing this isn't just a re-wrap of an existing cell. Hard for me to believe a presumably small company (whose website doesn't even function) can R&D, engineer, produce, and bring to market a cell claiming to outperform those produced by the biggest names in the battery industry. But, I'm a skeptic by nature, so...

My curiosity is certainly piqued and I will be following any additional developments with interest.

I agree with everyones posts so far, It is typical that we see mah go down a bit as the amperage goes up. I am just curious as they list them at 35a continuous. I have seen the vamped batteries rated at 40a and those are now known to be pulse ratings and even kidney puncher does not recommend a build lower than .2 on the vamped series

Looking at you notsubohmduracell...

At any point in time in the market, yes there is going to be your high current discharge vs your high capacity cells. Something for everyone.

But no... capacity doesn't go down as current goes up or vice versa. Actually as battery tech evolves both are going up. Used to be AW held the crown with a 24 amp 1600mah and a 10 amp 2000 mah cells. Now we have a good choice of 20 and 30 amp cells all boasting 2500 mah.

Being that the sonys are a couple years old, the market is pretty stagnant for round lithium cells currently. I'm kind of expecting another jump in tech shortly. Though this doesn't jump out at me as a likely fill for that void.

Do you have any clue what that will be? Is this it?

I would keep my eyes peeled on the established big names. They're the most likely. Their R&D departments are working hard to get the edge. You can be sure of it.

Let's just say we have plenty of reason to be skeptical. There's been "original", "sub ohm" batteries popping up from new names too often to lend any credibility to any of them lately.

Not to mention the timing. The Sony cells go awol and like magic there's a new mfr in town? Really?

I need to see some independent testing before I'll even consider the hype.

No, the opposite is true. To get the safe continuous discharge of a battery you would multiply it's 'C' rating by it's capacity. So as the capacity goes up, so does it's safe discharge limits for the same chemistry/construction battery. You can learn more about it here: Battery Discharge Methods
