This cell has overrated current and capacity ratings. It performs below average, a bit worse than the Nitecore 7A 700mAh cell I tested earlier.

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.

The two cells I tested delivered 732mAh and 743mAh at 0.2A down to 2.5V.

I am estimating this AWT’s ratings at 6A 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.

This is the third 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.

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.

While not perfoming quite as well as the Vapcell 1100mAh in my testing this is a pretty good 18350. It delivers a bit less total energy, its Wh (watt-hour) spec, and runs a touch hotter than the Vapcell so I have given it a slightly lower current rating than the Vapcell.

Aspire does not list the ratings on the cell’s wrap but does include a paper insert that seems to indicate that they rate it at 10A. The insert also mentions a 15A “Vaping Simulation” rating using 10 second pulses spaced 5 seconds apart.

I really wish Aspire put the current rating on the cell as it is easy to lose the paper insert, leaving us with a cell with no rating. This can be a safety issue as well as a performance one.

The performance of any 18350 really suffers at high current levels like 15A 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.

The two cells I tested delivered 1154mAh and 1166mAh at 0.2A down to 3.2V.

I am estimating this Aspire’s ratings at 9A and 1100mAh. 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.

While both of the cells I tested delivered a bit over their rated 700mAh of capacity they were poor performers with an exaggerated current rating. Their large voltage sag made them essentially unusable at 10A, as displayed by the huge drop in the Wh delivered between 5A and 10A.

While this cell has an exaggerated current rating is it a good performer. It is identical in appearance and similar in performance to the Golisi S35 and Efest 35A 3700mAh 21700’s.

Both of these Listman cells had a bit over 4000mAh capacity. While this is a good thing it indicates that this cell might not be the exact same cell as used by Golisi and Efest.

Upon learning that this cell had an exaggerated rating, iJoy (the ones who donated the cells for testing) told me that they will instruct the factory to change the rating on the wrap from 40A to 30A. While I would definitely prefer that a cell was tested and rated accurately before being sold I am glad that iJoy is willing to change the exaggerated current rating.

There are earlier versions of this cell with a useless 60A “pulse” rating on the wrap. This was a ridiculous rating and I am glad it was removed.

I am estimating this cell’s ratings at 30A and 3800mAh minimum, though you might get more capacity from them than that.

This is an accurately rated high capacity cell that performs well up to about 10A-15A/30W-45W or so. Above that and the Golisi S35 3750mAh or Efest 3700Ah 21700’s are better performers due to their lower internal resistance.

It seems to be the same cell as used by the overrated Basen 30A 4000mAh 21700.

While it has the continuous rating marked on the wrap it also has a useless “max pulse” rating. This is a shame as it is accurately rated otherwise.

The two cells I tested delivered 4125mAh and 4243mAh at 0.5A down to 2.5 V, over their 4000mAh rating. While this is typical for Samsung, Sony, LG, Panasonic, and Sanyo cells I don’t often see it for others. 

It’s great though and I encourage other cell wrapping companies to stop using the highest capacity they find for a group of cells for their rating. The rating should be lower than the lowest capacity delivered by any cell, i.e., it should be a minimum capacity rating. It appears that this is what MXJO did.

I am estimating this cell’s ratings to be 20A and 4000mAh.

These EnerCig samples were sent to me as a possible alternative for the incredible A123 ANR26650M1-B cells and they come close. These cells can easily be used at 40A.

These are LFP chemistry Li-Ion cells though (LiFePO4, lithium-ferrous-phosphate) and there are things you need to take into account before using them.

DO NOT USE THESE CELLS UNLESS YOU ARE COMLETELY FAMILIAR WITH OHM’S LAW, SERIES MECH MOD OPERATION, AND THE DIFFERENT CHARGING REQUIREMENTS FOR THESE CELLS.

While they are the safest chemistry we have easy access to they run at a lower voltage, 3.2V nominal, versus the 3.6V/3.7V nominal for the typical cells used for vaping.

This means that at high current levels these EnerCig’s run at under 3.0V and can’t be used in regulated mods as the mod will quickly signal low/weak battery. They can be used in series in a mechanical mod though.

Critically important is that all LFP chemistry cells must be charged to about 3.6V.

DO NOT USE THE STANDARD 4.2V CHARGING VOLTAGE!

This EnerCig has a 3.65V charging voltage specification and you can easily charge at 2A.

While not delivering the same amount of energy as the A123 26650 (A123 = 6.9Wh vs EnerCig = 6.0Wh at 40A down to 2.5V) this EnerCig does hit harder for a lot of a 40A discharge than the A123.

A123 cell’s are becoming very hard to buy now. These EnerCig’s are a good replacement in my opinion for series setups that can make the best of the high current rating but lower voltage of LFP chemistry cells. You will need to use a 3.6V/3.65V charger.

These EnerCig’s are great performing cells with incredibly flat discharge curves. That is, their voltage is very steady during use (after the initial voltage sag) all the way until the end. They perform more like LiPo’s than our standard round cells and this is good for use in a mech. The extra safety provided by the LFP chemistry is a great bonus along with their very low DC internal resistance.

The two cells I tested delivered 2323mAh and 2379mAh at 0.5A down to 2.5V.

I am estimating this cell’s ratings to be the same as those listed in their datasheet, 46A and 2300mAh. As with any cell though, operating at below its rating is more efficient and extends cell life. Operating two in series can easily do this though as the higher voltage increases the power to the coils without having to run at high current levels.

These were purchased to add to my “reference cell” library to help with counterfeit detection. This is a low performance, low capacity cell. It’s just not worth considering using for vaping.

I am estimating this cell’s ratings to be the same as Samsung’s ratings, 15A and 2000mAh.

In my opinion this is a rewrap of the great performing Sony VTC5D, appearing and performing identically to the Sony. It performs slightly better than the VTC5A but not quite as well as the VTC6A.

In my opinion this is a rewrap of the Sony VTC6, appearing and performing identically to the Sony. Because of the hugely exaggerated ratings I am giving this cell a Do Not Buy recommendation.

This Cylaid’s 40A continuous rating is hugely exaggerated as Sony rates the VTC6 at 15A continuous. Operating at higher current levels is mentioned in the datasheet but you must not exceed its 80°C maximum temperature rating. Rating this cell at 40A is outrageous.

This Cylaid’s 60A “pulse” rating is useless as we don’t know the width of the pulses, the time between them, and the criteria used to set the rating.

The Sony VTC6 is rated at 3000mAh so this Cylaid’s 3100mAh capacity is exaggerated too.

I am estimating this cell’s ratings to be the same as Sony’s ratings for the VTC6; 15A continuous, higher if not allowed to reach 75°C, and 3000mAh.
