BATTERY MOOCH

I would like to personally welcome Battery Mooch to TasteYourJuice.com.

“Mooch” is well known in the industry as the “battery guy” and is quite popular on the ECF. I’ve worked with Mooch several times in the background and he’s always been quite helpful and knowledgeable in answering my questions.

Although I have some experience with battery testing, Mooch has all the experience I lack so I though it a good fit to offer him his own page here on TasteYourJuice.com.

If you look to the left, you’ll see the new Battery Mooch page under Information/Resources. His first article can be found there as well.

WELCOME MY FRIEND!

Who is Battery Mooch?

My name is John Muchow, some of you may know me as Mooch on ECF and FB and Mooch315
on ECR. I have been vaping since April, 2015 and haven’t smoked once since I
started!

I was born and raised in New York City and still live there now. Since 1992 I have
been designing and building electronic devices for a large number of clients. My
first products were camera remote-control systems for sports photographers. As these
systems, and other devices, transitioned from wired to wireless the performance of
the batteries they used was very important as there was no way to replace them
during use. This led to me doing more and more battery testing and developing the
electronics to charge, test, and protect them.

As battery technology advanced, from NiCd to NiMH to Li-Ion and now
ultracapacitor/Li-Ion hybrids, the devices I built and the battery testing I did
advanced along with them. I started specializing in power management electronics;
battery chargers, energy harvesters (for charging from heat, light, or
vibration/movement), power supplies, battery analyzers, electronic loads for battery
discharging, and battery management/protection systems. This is the work I still do
today.

My clients have included the US Army, National Geographic, Sports Illustrated,
Eastman Kodak Company, and hundreds of other companies from large to small. Part of
the work I’ve done for a lot of my clients has been battery testing. Sometimes they
want to recommend a good battery to their customers. Other times they’re batteries I
have chosen to combine with my electronics to form a complete, protected power
source for them to incorporate into their products.

Depending on my client’s requirements this testing can take up to several weeks to
complete. I use a subset of these tests when evaluating the batteries we use when
vaping. This includes continuous-current tests to establish the battery’s true (and
safe) ratings. They also help to determine if there’s any risk of venting if one of
our mods autofires or a mechanical mod’s button is accidentally pressed. The
pulse-current tests measure the degree of voltage sag we would see when vaping at
different current levels. Both types of tests are done the same way for every set of
batteries I test.

This consistency in the testing allows for direct comparison of the performance of
different batteries even if the pulse discharging I do doesn’t match the way you
vape.

Safety is my number one priority. While I often test at discharge current levels
that can result in unsafe battery temperatures, this is the only way to figure out
what a battery’s true and safe ratings are. No battery is totally safe but we can
certainly avoid taking unnecessary risks.

My blog at ECF has the results of all my testing and a few articles on batteries,
battery safety, etc.:

https://www.e-cigarette-forum.com/forum/blogs/mooch.256958/

I have also listed the equipment I use and the steps I follow when testing. This
allows anyone to replicate my tests if they want to:

My battery test results offer you a resource you can use when choosing a battery
that will not only be safer for the way you vape but will also give you great
performance.

I’m looking forward to contributing to TasteYourJuice.com and I want to thank
PBusardo for the opportunity to help spread the word on exaggerated battery ratings
and battery safety!

Latest Battery Updates

A BATTERY MOOCH POST: Radio Shack 20A 2500mAh 18650…accurately rated but 25R is better, paper top ring

While this cell is accurately rated it is not a great performer. But it is certainly an option if you need a 20A cell and no other better performing cells, like the Samsung 25R, are available.

The two I tested showed a bit of inconsistency in performance between them but it wasn’t bad.

These Radio Shack cells use a paper ring as the top insulator. Do not let eliquid, or any liquid, get on the top as it could weaken the ring and/or cause rusting underneath.

The two cells I tested delivered 2712mAh and 2713mAh at 500mA (0.2C) down to 2.5V. This is good performance for a cell rated at 2500mAh.

I am ESTIMATING this Radio Shack’s ratings to be 20A continuous (about 60W) and 2500mAh.

Two cells were purchased for the purposes of testing by me.

A BATTERY MOOCH POST: iJoy 25A 1400mAh 20350…hugely overrated, paper top ring, must still rate at 7A

Two of these cells are included with the iJoy Avenger Baby mod and one is used inside the iJoy Diamond VPC kit mod.

A total of six cells were tested. Their performance varied wildly with the worst cell delivering about 1/3 the vaping time of the best cell at 10A (about 30W) down to the 3.3V cutoff used in the iJoy Avenger Baby mod.

This inconsistency is huge and is a big concern as it forces me to rate all of them at the performance level of the worst cell. You might get a decent performer or you could get one even worse than the ones I had.

One possible cause for this inconsistent performance could be the badly done internal spot welds in the cells I tested. Some of the welds burnt through the metal, resulting in a very poor connection and some spot welds missed the metal they were supposed to weld down.

I sent iJoy photos of some of these badly done welds and they informed me that they are speaking to the factory to revise/improve the spot welds and overall performance of these cells. I look forward to retesting them when these cells are released.

This iJoy cell uses a thin paper ring as the top insulator. Do not let eliquid, or any liquid, get on the top of the battery as it could weaken the ring and/or cause rusting underneath.

The six cells I tested averaged approximately 1440mAh at 280mA (0.2C) down to 2.5V.

I am ESTIMATING this iJoy’s ratings to be 7A continuous (about 20W) and 1400mAh. You could get lucky and end up with a better performer, up to about a 15A rating, but never assume you have one like that. I recommend staying below 20W per battery until the revised cells are available. This is 20W for the iJoy Diamond VPC mod and 40W for the iJoy Avenger Baby mod. 

Two cells were donated for the purposes of testing by Mike Vapes (https://www.youtube.com/channel/UCt3WcCLs8Zm-zZNcqgixyMw), two were donated by Kimmy Vapes (https://www.youtube.com/user/luck4kim), and two were donated by Bob The Vaping Computer Guy (https://www.youtube.com/channel/UCr6745zQfrRa5GBcoT2cd_g).

A BATTERY MOOCH POST: iJoy 25A 1400mAh 20350…paper top ring, hugely overrated!

I was very excited by the release of this 20350 and was hoping it might be a 15A cell, perhaps even 20A. Alas, I was greatly disappointed by the test results.

I’ve only tested two cells so far but both were very poor performers with terrible cell-to-cell consistency. I am trying to find a way to get at least four more cells for testing. Until then I am giving them a Do Not Buy recommendation.

One cell performed at about a 7A rating and the other performed as a 10A cell. The better performing iJoy only equaled the performance of the Vapcell 10A 1200mAh 18350. The other iJoy was a lot worse than the Vapcell 18350.

Based on their inconsistent cell-to-cell performance I think these are China manufactured cells.

This iJoy cell uses a thin paper ring as the top insulator. Do not let any eliquid, or any liquid, get on it as it could weaken the ring and/or cause rusting underneath.

The two cells I tested delivered 1441mAh and 1446mAh at 280mA (0.2C) down to 2.5V.

Until I can get more cells in for testing I am ESTIMATING this iJoy’s ratings to be 7A continuous (about 20W) and 1400mAh. The ratings will be adjusted as necessary when more testing is done.

A BATTERY MOOCH POST: Golisi S32 30A 3200mAh 20700…it has changed, now only 25A

This cell has changed. It now runs hotter, by a few degrees-C, and at a slightly lower voltage than it did in my previous tests. This earns it a lower current rating. It appears to be the same cell as used by the 25A versions of the Vapcell gold 30A 3100mAh and QSO Orange 30A 3100mAh cell but I cannot be sure of this.

The two Golisi’s I tested delivered 3086mAh and 3117mAh at 640mA (0.2C) down to 2.5V.

This QSO has the same top contact structure as the 25A version of that Vapcell but the metal can of the previous 30A version. The crimp at the top is a bit different than both though. I give up trying to understand all the variations coming out of whatever factory makes these. It is a 25A cell now.

The two QSO’s I tested delivered 3156mAh and 3170mAh at 620mA down to 2.5V.

I am ESTIMATING this QSO’s ratings to be 25A continuous and 3100mAh.

A BATTERY MOOCH POST: iJoy 40A 3000mAh 20700…third version of this battery, hugely overrated

This is the third version of this battery. The first had a five top “leg” top contact, the second had four legs, and this one has five legs but with a small “tab” at the bottom of each cutout in the top contact.

While these cells delivered roughly the same amount of energy as the original five leg version at moderate to high current levels (and much more than the four leg version) it did so at a MUCH higher temperature so it must be given a much lower current rating.

There was a decent difference in performance between the two cells I tested, much more than that typically seen between cells from Samsung, Sony, etc. This makes me think these iJoy cells are manufactured in China. But I don’t know for sure.

While the two cells I tested might be able to be given a continuous current rating between 20A and 25A I am sure they are not the hottest running cells from their batch. This forces me to rate this cell at 20A.

The two cells I tested delivered more mAh than their rating, 3188mAh and 3176mAh at 600mA down to 2.5V. Because this cell has already changed twice I am not giving it a capacity rating above the 3000mAh rating on the wrap.

I am ESTIMATING this iJoy’s ratings to be 20A continuous and 3000mAh.

A BATTERY MOOCH POST: Juiced 20A 3000mAh 18650…accurately rated (sort of), seems identical to Samsung 30Q

These cells look the same and perform essentially the same as the 15A 3000mAh Samsung 30Q. Samsung rates the 30Q at 15A continuous but the datasheet mentions operation at 20A. Never let these cells exceed 75°C if running them at 15A-20A. The Samsung 30Q is a great performing battery though.

The two cells I tested delivered 3108mAh and 3109mAh at 600mA down to 2.5V.

I had some questions regarding Juiced saying their cells were specifically developed for vaping. I have asked Juiced about this and am waiting for their response.

Juiced uses “IMNR HYBRID” on the wrap as, it seems, a battery chemistry designator but I have never seen that used before. The IMR and INR manufacturer model prefixes (they’re not chemistries) are common though. INR is already a prefix used for “hybrid” chemistry cells so using IMNR is a bit confusing in my opinion. But, each company is free to create any designator they want.

The Juiced web site says that this cell uses a “Lithium-Manganese, Nickel” chemistry. The Samsung 30Q uses NCA chemistry though, nickel-cobalt-aluminum. If this is not a 30Q then perhaps it is NMC chemistry, nickel-manganese-cobalt? That is a common chemistry used by vapers. It looks and performs the same as a 30Q though.

The Juiced web site mentions that they spent years researching and testing the best 18650’s, found this cell, and then improved it. I have requested info on what changes they have made. I have also requested the summaries of their previous testing as I am sure our community would love to know how different cells performed for Juiced. Any other test results we can get is great to have!

I am ESTIMATING this Juiced cell’s ratings to be 15A continuous, 20A temperature-limited to 75°C, and 3000mAh.

Five cells were purchased for the purposes of testing by me.

A BATTERY MOOCH POST: VRK 30A 3000mAh 20700…looks like other five-leg ones, hits harder but runs hotter

These cells appear identical to the other five-“leg” top contact cells being used by several companies. It runs hotter but performs a little better than the ones I have tested previously. I do not know if this is unique to the batch of cells VRK is using or if all the five-leg cells are now performing this way. Retesting of the others will be done but I do not know when.

These VRK cells have a paper top ring insulator that absorbs eliquid. This might weaken the ring and if the eliquid absorbs moisture then rust can form under the ring. If using this cell do not let eliquid get on the top of it.

This cell is a decent performer but runs too hot to be rated 30A in my opinion. It also showed a big difference between the two cells in the delivered Wh at high current levels.

The two cells I tested delivered 2959mAh and 3023mAh at 600mA down to 2.5V. It cannot be considered a 3000mAh cell.

I am ESTIMATING this VRK’s ratings to be 25A continuous and 2900mAh.

A BATTERY MOOCH POST: Vapcell Blue 35A 3000mAh 21700…looks like LG H30 but only 30A 2900mAh

These cells appear identical to the LG H30 samples I received earlier this year but they did not meet LG’s 3000mAh minimum capacity rating. The two cells I tested delivered 2946mAh and 2947mAh at 600mA (0.2C) down to 2.5V.

This cell is a decent performer but the Samsung 30T is a MUCH better choice at high current levels, delivering about 30% more energy down to 3.2V at 30A. The Samsung 40T will also outperform it at up to about 20A-25A.

I am ESTIMATING this Vapcell’s ratings to be 30A continuous and 2900mAh. LG lists a 35A “max” discharge rating for the H30 but I believe that to be a temperature limited rating. LG lists a max cell surface operating temperature of 75°C and the two cells I had reached 74°C and 75°C at 30A. The “fast discharge” rating in the datasheet is 30A.

This is an almost accurately rated rewrap of the 21700 size version of the Sony VTC6A. It appears identical to, and performed essentially identically to, the VTC6A’s I recently tested.

The QSO’s I tested have the tiny QR code square on the bottom, same as the VTC6A’s I tested.
