A BATTERY MOOCH POST: Eizfan 30A 3750mAh 21700…slightly overrated but good performer
This is a good performing cell that is slightly overrated. It appears to be the same cell that was used for the Golisi S35 and Efest 35A 3700mAh 21700’s when I tested them. This Eizfan runs a little hotter though so I have given it a 25A rating. Since they all might use the same cell the Golisi and Efest will need to be retested to see if they are also 25A now.
The capacity for the four Eizfan cells was 3857mAh to 4093mAh. China manufactured cells typically have worse cell-to-cell consistency, versus those from Samsung, Sony, etc., but this is a wider capacity range than I usually see. All of the cells I tested easily met their 3750mAh rating though.
Four cells were donated for the purposes of testing by Efan (https://efantech.en.alibaba.com). Thank you!

This is one of the hazards of using “rewrapped” batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

A BATTERY MOOCH POST: AWT 35A 4800mAh 21700…obscenely overrated, DO NOT BUY
Another AWT cell deserving a Do Not Buy recommendation for the outrageously exaggerated current rating on the wrap.
This appears to be a rewrap of the pre-production LG M50 which is rated at 10A. This AWT is identical in both appearance and performance to the M50.
Two cells were purchased by me for the purposes of testing.

A BATTERY MOOCH POST: AWT 40A 3300mAh 18650…obscenely overrated, DO NOT BUY
This is ridiculous. This cell’s true rating appears to be under 10A but AWT has rated it at 40A on the wrap. I recommend not buying it or using it at any level. At just 20A, one half of the 40A rating given to this cell by AWT, it reached a temperature of 113°C!
PLEASE REMEMBER: There are no 18650’s we can buy with a capacity over 3000mAh that can have a rating over 10A and many are rated down near 3A.
Several cells were purchased directly from AWT and donated for the purposes of testing by someone who prefers to remain anonymous. Thank you!

A BATTERY MOOCH POST: Pre-production Samsung 50E2 9.8A 4900mAh 21700…great battery!
These are not the Samsung 50E pre-production samples that are floating around and rewrapped by some companies. The 50E2 is a much better performing later release of the 50E indicated by a “2” in the lower left corner of the printing on the wrap.
It’s similar to what Samsung did with the 25R. There was the blue-wrapped 25R2, then the green-wrapped 25R5, followed by the green-wrapped 25R6. Each one having a tweak to its performance.
I do not know if these will end up being the cells Samsung uses for production or if they will make additional tweaks but I am very impressed with the performance improvements over the 50E. Their internal resistance is very low which helps keep temperatures down and the voltage up, increasing the energy this cell can deliver.
This is an accurately rated, great performing ultra-high capacity 21700 cell. The datasheet lists the minimum capacity at 4753mAh and standard capacity of 4900mAh. The two 50E2’s I tested delivered 5051mAh and 5062mAh at 1A (0.2C) down to 2.5V. The DC internal resistance measured 20.7mOhms and 20.8mOhms. This is astounding consistency and fantastic to see.
The DC internal resistance of these cells is the same as a lot of the 20A 18650’s we use. But the current rating of the 50E2 is limited by its 60°C operating temperature limit. You cannot operate these at high current levels or temperatures. However, the low internal resistance of the 50E2 makes it a great performer.
This Samsung 50E2 outperforms the (earlier) Samsung 50E, the Samsung 48G, and the LG M50 samples I recently purchased (more about the M50 later). I do not know when the 50E2 will be available for sale or who will carry it but I hope it is soon.
I am rating the Samsung 50E2 at 10A/30W and 4900mAh. I will be retesting these again when they reach full production.
Two cells were donated for the purposes of testing by ENERdan GmbH (https://enerdan.de/en/). Thank you!

REASON TV: Stossel: Let Them Vape
Vaping may not be safe, but it’s a lot safer than cigarettes.
Our government says e-cigarettes and vaping are the latest “epidemic” among teens. So the Food and Drug Administration (FDA) says it will restrict them. Cities across the country are banning e-cigarette use in public.
But e-cigarettes help smokers quit traditional cigarettes. Michelle Minton of the Competitive Enterprise Institute tells John Stossel that people have misconceptions about e-cigarettes. “It’s about 95 percent less harmful than a normal traditional cigarette,” she says.
That’s because e-cigarettes let people get a hit of nicotine without actually burning tobacco. The burning of paper and tobacco leaves is what makes cigarettes so dangerous.
Minton admits that the nicotine in e-cigarettes is addictive. But “on the spectrum of drugs that you can become addicted to, nicotine and caffeine are very similar to each other.”
The Surgeon General says there are other health risks to vaping: “Besides nicotine, e-cigarettes can contain harmful and potentially harmful ingredients.”
Despite the dangers, researchers seem to agree that e-cigarettes are substantially less dangerous than combustible cigarettes.
Other studies concluded that long-term e-cigarette use is “associated with substantially reduced levels of measured carcinogens and toxicants relative to cigarette-only smoking.”
Nevertheless, the FDA threatens to crack down to discourage kids from using e-cigarettes.
Minton says that is a bad idea: “Do we want children to become addicted to anything? No….But keeping a small percent of teenagers from trying e-cigarettes is not worth sacrificing adults whose lives could be saved.”
