A BATTERY MOOCH POST: VRK 25A 3750mAh 21700…an average 20A battery
This VRK appears to use the same cell as Basen and CoilArt 21700’s, not a great performer. The Golisi S35 and Efest 3700mAh are better and have higher current ratings. Even the five “leg” top contact 20700’s from iJoy/Efest/EBAT/Ampking and others perform a little better and have higher current ratings too.
The 40A ”Max Discharge” rating on the wrap is useless as VRK doesn’t define what that means. Some type of “pulse” rating? We can’t use it to compare against any other cell unless we know the pulse width, time between pulses, and what criteria they use to set the rating (Temperature? Voltage sag? Cycle life? A combination of those?). That’s only if all the cell wrapping companies use the same pulses and criteria too.
The two cells delivered 4118mAh and 4116mAh at 0.5A down to 2.5V. I don’t know why VRK rated this cell at 3750mAh unless perhaps they are expecting to change cells or, for this batch, they switched over to a different one?
I am estimating this VRK’s ratings at 20A and 3750mAh. I’m not giving them a higher capacity rating due to the risk of the cell being changed.
Two cells were purchased for the purposes of testing by me.

These tests only note the estimated ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! 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.
Any rating in my ratings tables can change at any time as different grade cells appear on the market, we get swamped with fakes, or new information becomes available to me. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.

A BATTERY MOOCH POST: Blackcell Quantum 40A 3000mAh 21700…only 30A-35A but a great performer
While this 21700 cell has slightly exaggerated current rating it performs better than the Sanyo NCR20700A and is a great choice for mech/unregulated mods. Even for regulated mods at high current levels, over 25A, it’s a great choice if the Samsung 40T or its rewraps aren’t available. The Samsung 30T performs a lot better though.
I welcome the efforts of any company that wants to change over to rating their cells more accurately as Blackcell seems to be doing now. Their recently released 22A 2523mAh Electron 18650 is accurately rated. While the current rating is exaggerated with this 21700 it is a huge jump in accuracy over their preposterously rated 40A and 50A 3100mAh 18650’s that they used to sell. Hopefully Blackcell updates the wrap for this cell soon.
I know accurate ratings terrify the marketing departments for these companies, because they’re lower, but I feel strongly that accurate ratings will result in better sales over the long term. We want honesty, we want greater safety, and we will buy from the companies that offer this.
I am estimating this Blackcell’s current rating at 30A-35A depending on its cycle life requirements and how hot Blackcell allows the cell to run. Its estimated capacity is 3000mAh.
Three cells were donated for the purposes of testing by Blackcell (http://www.blackcelltech.com). Thank you!

A BATTERY MOOCH POST: 18350 Shootout Results – Top three performers for 2018
1) Vapcell flat top purple 1100mAh 10A (accurately rated)
2) Aspire flat top 1100mAh 10A (9A rated in testing)
3) Keeppower 1200mAh 10A (1000mAh, 9A rated in testing)
There isn’t a huge difference between the three but the Vapcell could run up to 25% longer in a regulated device and is the better choice for unregulated/mech mods as it hits the hardest.
The Aspire and Keeppower have similar run times and current ratings and I don’t think you’d see a difference between them. The three seem to be different cells though.
I wasn’t able to test the AW 18350’s due to them not being available anywhere. There was a mention of a flood at the factory a while ago but I cannot confirm that. I do not know when, or even if, I will be able to test them.
The two button top cells I found and tested, the Imren and MXJO, were pretty terrible performers compared to the three above. If you have to pick one, pick the MXJO and stay under 5A. Preferably under 3A.
I hope to test another batch of 18350’s in a few months.

A BATTERY MOOCH POST: Keeppower 10A 1200mAh 18350…above average 9A battery, only 1000mAh though
While this cell has a close to accurate 10A continuous current rating on the wrap it is in very tiny print and a useless 15A “pulse” rating is also used. This is confusing, unnecessary, and I would like to see this type of rating stopped.
It is an above average performer but a bit worse than the Vapcell and Aspire cells. The two Keeppowers I tested delivered 1040mAh and 1042mAh at 0.2A down to 2.5V. This is quite a bit below their 1200mAh rating.
I am estimating this Keeppower’s ratings at 9A and 1000mAh. Current ratings for high internal resistance cells like these are a combination of the temperature the cell runs at and how badly the voltage sags, i.e., its Wh specs.
The performance of any 18350 really suffers at higher current levels due to their very high internal resistance, leading to huge voltage sag. I recommend staying under their continuous current rating. This results in much more efficient operation and much longer vaping time.
This is the last in a group of seven 18350’s I am testing and I will be posting a shootout between all of them after the individual test reports are posted. The top three performers will then be identified.

CONGRATS KEN!!
Congratulations to Ken!! The happy “Not A” Contest WIENER of the Ovanty Vega!!
LOVE this picture and the kind words Ken!! Thank you and Vape Happy my friend!!
I really like the Ovanty Vega that I won! Screens are easy to understand and I am happy with the Temperature Control.
Thank you Phil for all that you do to help smokers get off combustible cigarettes!!! I was a smoker for forty-seven years and have now been vaping for Seven years. Your Reviews were the first that I watched, and still do! You always tell it like it is. Glad to be one of you “Friends”.
Ken
A BATTERY MOOCH POST: Efest 10.5A 700mAh 18350…an average performing 7A battery, same as Nitecore
While this cell has an accurate 7A continuous current rating on the wrap it is in very tiny print and a useless 10.5A “pulse” rating is above it in much larger type. This is confusing, unnecessary, and I would like to see this type of overrating stopped.
It is an average performer, a bit better than the overrated AWT 10.5A 850mAh cell. It appears to be the same cell as the Nitecore 7A 700mAh 18350.
The two cells I tested delivered 713mAh and 708mAh at 0.2A down to 2.5V.
I am estimating this Efest’s ratings at 7A and 700mAh. Current ratings for high internal resistance cells like these are a combination of the temperature the cell runs at and how badly the voltage sags, i.e., its Wh specs.
The performance of any 18350 really suffers at higher current levels due to their very high internal resistance, leading to huge voltage sag. I recommend staying under their continuous current rating. This results in much more efficient operation and much longer vaping time.

A BATTERY MOOCH POST: Imren Blue Unrated 800mAh 18350…a poor performing 3A battery
This cell has an accurate capacity rating but is a poor performer. Even at just 5A it delivered less than 1/2 the energy of the other 18350 cells I tested due to its incredibly high internal resistance. This means very short run times at anything above a couple of amps.
The two cells I tested delivered 874mAh and 887mAh at 0.2A down to 2.5V.
I am estimating this Imren’s ratings at 3A and 800mAh. Current ratings for high internal resistance cells like these are a combination of the temperature the cell runs at and how badly the voltage sags, i.e., its Wh specs.
The performance of any 18350 really suffers at higher current levels due to their very high internal resistance, leading to huge voltage sag. I recommend staying under their continuous current rating. This results in much more efficient operation and much longer vaping time.
This is the fifth in a group of seven 18350’s I am testing and I will be posting a shootout between all of them after the individual test reports are posted. The top three performers will then be identified.
