Another AOSO battery graph also shows impossible performance!

[Mooch]

Ni Xue of Aosibo recently posted a discharge graph of the AOSO 40A 3100mAh battery allegedly on Facebook showing its performance during a 40A continuous discharge. I don't know if it's an equipment malfunction or if they're falsifying the data but this graph shows the battery performing at impossible levels:



Here's why this graph can't be correct:

- The horizontal axis shows that it took 11 minutes and 52 seconds to finish the 40A discharge. If you do the math that is about 7900mAh of capacity for this battery at 40A! That's ridiculous.

- The voltage starts at about 3.90V. No 18650 battery ever made has such a small voltage sag at 40A. The LG HB6, Sony VTC4, and VTC5A drop to 3.4V-3.5V at 40A. Sagging to 3.9V happens at 10A-15A for most decent 18650 batteries.

- Using the 3070mAh claimed capacity for this battery and the 11:52 (min:sec) run time the math says that's about a 15A discharge level for this graph.

So, no matter how you look at that graph it's not real. Either their equipment is malfunctioning or they falsified the data.

I haven't tested this 40A 3100mAh battery yet but here are the links to my previous Aosibo battery tests and their response to my testing:

AOSO Brown 30A 1600mAh 18650 Bench Test Results...only 15A but 2500mAh?

AOSO Red 42A 2600mAh 18650 Bench Test Results...dangerously overrated, falsified graphs

AOSO Black 60A 2800mAh 18650 Bench Test Results...most overrated 18650 so far

AOSO Brown 25A 3500mAh 18650 Bench Test Results...only a 10A battery, probably MJ1

Some People's greed is driving them to scamming... Unbelievable! and the best of all is their response to the whole issue: "Therefore, we will not scruple to spend greater cost to let the public have a chance to experience the best battery.
Total 200 pairs of Free AOSO batteries (400pcs) to all e-cigarette consumers." We will not spent money or even try to get our cell closer to our claimed numbers we'll just give away some!!!!

You just have to love LG-Samsung-Sony-Panasonic after these kind of incidents!

Trying to claim Efest's filthy crown

Mooch, the company that made this battery may be associated with the one that used to advertise, "Add this to your tank and make your car get 100 miles per gallon!".

Didn't believe that either ...

"Say it ain't so Joe!"
Who would do such a thing?

As Efest was mentioned, I can't say "it's getting worse"... but it ain't gonna end either.

I almost went for that giveaway figuring I've got a few 18650 flashlights, then I said... naw, crap would still probably vent on me.

Someone did take one for the team though (I think it was Steve {Wingsfan}) so if he gets a pair we'll see what Escribe has to show. At 10-15A though, there's just nothing we lunghitters can really trust them for.

Honestly... claiming over 3000mAh at 40A?
Pull the other one... it's got bells on.

I charged a couple of purple Efest "3000 MAH" batteries today that I drained down to 3.2v in a dual battery Smok Koopor Plus. My Xtar VC4 showed that it pumped about 2050 milliamps of current back into each battery. They are about a year old and have been rotated in 3 paired sets in the Koopor along with a pair of 25R's and a pair of VTC4's. They probably have 100 charges under their belt and perform about as well as the others. I don't think they were anywhere near 3000mah batts when new, but they have performed well enough to continue using.

I'd love to compare them to a new set, but those are the last Efests I'll ever buy. I bought them just to have a pair to marry when I bought the mod! The vape shop was out of everything but Efests.
