Where were you when I needed a great math instructor!? Once again I understood the material in a practical way. Thank you so much sir for helping us. If you're not a teacher, you should be!
We should call it 'Mooch Law' instead of Ohms law! It has a better ring to it! Keep doing your thing, brother. You are a pillar in the vape community and you are awesome!
I've said it before and I'll say it again... Mooch, what you do for the vaping community is awesome! I wish these easy to understand explanations would have been around when I started vaping 5 years ago. And I just love your White Boards! Please keep it up. Thanks alot Mooch! P.S. Suggestion for a future video... How to check your charger (with a Multimeter). Is it still in good working condition? Is it still charging to the correct Voltage (i.e. can I trust what it says on the display)? ....... etc.
I always heard about mooch battery classification and test , in the half of this video i see that is you mooch , i wanna thank you a lot for all what you do U're a legend 🏆💪❤️
I'm an Electrical and Mechanical Engineer vaping for over 7 yrs and I still learn new stuff from every one of your vids. If you vape ,you should be Subbed to this channel. Cheers John.
This is the video I've been waiting for. Thanks. I've made two mechanical and two unregulated. One series and one parrel. I kept my builds high since I wasn't sure exactly how amperage was. I always make sure my builds were safe for a single battery. Now I know I can go a little lower. Thanks again for another great video.
james whiting I'm running a .41 on my series. Boy does it hit. I always use a calculator to check the amps my build draw. Parallel was the one I was a little worried about. I run Samsung 25r I never went over 20 amps on my parallel.
Excellent, excellent, excellent. Every vaper should be required to watch these. I am constantly sending people from Facebook here to learn this stuff, it is essential. Thank you Mooch.
Well done Sir! This isn't basics anymore. This is everything for Series and Parallel that should be available in one short video. This time I didn't learn one thing. This time everything was explained and more I know. Thank you on behalf of the community, it's gotta be said even if I'm not a player, and please never stop with the knowledge drops (even on the industry side). Peace!
Great video Mooch,your videos have added to my already known knowledge of battery safety....your info really helped me pull the trigger on a custom series mod.....thank you for all you do in the community👊👊❤❤👍👍
DAM. So much info an so important. U should be the biggest channel in vape. U are literally helping save teeth all around the world!! Lol. Thanks brother keep up the great work!
Great video once again. I really appreciate you taking the time to do these videos and helping us understand what we are dealing with in regards to Vaping... Keep up the great work !
Excellent vid again, Mooch! Very easy to understand, I think most beginners will be able to grasp the gist of this. I know these vids (in addition to your tests, and ECF posts) are taking a large slice of your spare time, but great work, please keep it up!
Battery Mooch Thank you for answering my question on why regulated devices are usually run in series rather than parallel. I never figured it'd be the same draw from the battery either way due to the amps being used in a different way. I figured you'd get better battery life with parallel when using a regulated mod but it's interesting to see just how regulated devices use the energy
Now I fully understand why people like parallel mods. 😗💨 Might I add you look like you are becoming more and more comfortable in front of the camera. 👍
Mooch you are getting to be a professional at this. Great video, love watching you. Always something in the videos that I did not know. Thanks for taking the time to make them. It is really really important stuff to know. Thanks again Jimmy
man, youre a legend just so you know. My country is talking about you before buying any. Some of them i would say, good luck to you okay? Keep up the good work.
Epic video once again Mr Mooch, i wish i could explain this to people as well as you do, from now on il just show them this video. Thanks for making it 👍
You might want to mention never to put a fully charged and a partially discharged or dead battery in parallel.. the current flow between them can be extreme due to the balancing effect of the parallel circut. Oh and thank you for everything you do. I have a feeling vaping would be far more dangerous if your testing weren't around keeping us informed and the companies in check when they inflate ratings. THANK YOU!
Thanks! While the current level can be high, as much as 30A, it is only for a short period of time and typically won’t vent the battery. Thermal runaway would be almost impossible just from this IMO. I agree that a charged and discharged battery should never be paralleled though!
Battery Mooch, thanks for the reply. Even though not something that should be done, it's nice to know it shouldn't be catastrophic. Thank you again for taking the time to do the tests and to explain battery safety so we can all be safe.
Great vlog mooch I’m an unregulated kind of guy so good info for newbs i wish there were more mainstream parallel or para-series mods out there looking forward to the new noisy cricket 20700 x
Very good video......so helpful! Another beauty of this, is being able to go back in case you missed something, or like me......bad memory......haha! Thanks, Mooch! :>
Regardless of how the math seems to work out, every parallel 2 battery regulated mod I've used outlasts even 3 battery series mods. Even with higher capacity but equally suited batteries. For example, the (parallel 2 batt) sigelei 100w TC compared to the newer (series 3 batt) sigelei 200w TC, 3 samsung 2500mah 25R5's in the 200 TC but 2 Sony woman VTC4's in the 100w TC parallel mod = parallel outlasting the 3 batteries with higher capacity. Where the tests I've done really shine is using all new 25R5's in both mods, the 100w TC would last 2 days with the same tank at the same watts, the 200w TC would have about 1/4 to 1/3 battery left at the end of the first day. I swapped the batteries around multiple times between the mods and got the same results consistently. So I compared the 100w TC to the wismec jaybo 3 battery series mod, same results with that mod. I used an external charger for all of this by the way. There is just something about parallel mods that really does last longer than series mods, the results I was getting was similar to my parallel unregulated mod also, just as a side note, as far as run time overall when matching the watts and current draw as closely as possible. But the parallel unregulated always beats the series regulated when trying the same thing. Again, even the 3 battery series mods.
Run time fundamentally depends on the cutoff voltage and the way you vape, including ramp up times for the coils. With all the variables accounted for any two battery mod shouldn’t be running longer than a three battery mod being used the same way. If it is there is a variable, or variables, that weren’t accounted for.
Hi Mooch, super awesome explanations! Just one thing I'm in little dissagreement and maybe you (or the community) may clarify as I might be wrong... when you state that a Series batt setup doesn't increase capacity, I agree, it doesn't, strictly talking about capacity it remains the same. But in fact those batteries will last longer as you are consuming half the current given you have now doubled the voltage (provided we are talking about the same load, to compare apples to apples). If instead you were maxing out the ratings and always aiming to get the most of the battery, then you must have had to reduce the resistance of the load to half of the original value in order to keep pulling 20Amps with twice the voltage and in that case that wouldn't be a fair comparison to "rate" a battery setup alone if it depends on the load. Right? Then I asked myself... If I want to somehow rate the setup by itself not messing with the load nor anything else but the batteries... isn't it there when we need the watt-hours??? At the end of the day I think what I'm getting confused with here is just that! because you will not increase capacity for a series, but you do double the watt-hours, being actually the same watt-hours for a 2P or a 2S, and both doubles the watt-hours you get with a single cell. So.. I thought I get it but I'm not completely sure whether or not I'm comparing apples to oranges.... Hope you can help clarifying! THANK YOU!
Yes, exactly. The capacity stays the same in a series setup. This is confirmed by drawing the same amount of current as was used in a single battery setup and noting the run time....which will not change. But for vaping you are correct. With a series setup we can lower the current we draw which allows for a longer running time for the (unchanged) capacity we have. So we can use the capacity spec for everything without problems but the Wh spec is MUCH more useful as it not only takes into account capacity but voltage too. This affects how hard a cell hits in a mech and how long a cell runs in a regulated device.
@@batterymooch awesome! Thanks for taking the time to respond!!! Keep up doing this great job you do! I admire you, wanna be like you when i grow up (already 37)
What happen if you mix different batteries ,, like put one 18650 and one 20700 , or one vtc6 with one vtc5a ... etc ?? VERY VERY GOOD CHANNEL please keep it up , i have heard about the vtc6a
Hey Mooch, Thanks for investing so much of yourself for our safety. All of your drawings show the batteries with the positives up and the negatives down. But my regulated duel battery mod has the batteries opposite of each other. Is this series or parallel?
Sorry, I don’t. Usually the first sign that a battery is reaching the end of its life is that it doesn’t run for as long as it used to. If it runs hotter then it’s getting old too.
Hey Mooch, I'm a little confused about something and was hoping you can clear it up for me. For use in unregulated devices is it safer with lower builds to use a battery with a higher continuous discharge, or batteries with higher pulse ratings? Also if a battery has a higher continuous discharge is it safe to say that the pulse rating would be higher than that of a lower continuous discharge battery? And when looking at batteries for lower builds should I be looking at pulse ratings or cd ratings?
Pulse ratings are absolutely useless. We can’t use them for anything as we don’t know the length of the pulse, the time between pulses, or the criteria used to set the rating. Use the continuous rating. Check out Ep2 of my Minding Your mAhs series,
Battery Mooch Yeah thanks, I just wanted to be sure. Love your videos, I would never have trusted myself going into mechanical mods without at least having a basic understanding of electricity which you have provided pretty well.
This video enlightens me so much.. Thanks for this video .. And i want to take this opportunity to ask this to confirm to one and only Sir Mooch.. For example, i'm setting up my limit of 0.20 ohms (or my minimum) on a single battery mechanical mod so that i cant go too far above 20A or 25A discharge rating (21A to be exact).. Is it safe to say that i can set my limit to 0.10 ohms in a dual battery parallel configuration of mechanical mod? Since i computed that it will land in the same 21A rating each battery, given it has a good connections and built. Hope you notice me Sir Mooch, more powers :)
The total current available in a parallel mod is not quite double the single battery rating since batteries do not share current equally. I recommend not using the theoretical doubled current rating. I recommend subtracting at least 15% from the doubled rating to get the rating to use, just to cover any unequal sharing of current.
Thanks Mooch! 2 Questions, first, I have a married, paired, purchased at same time set of 3 Samsung 25r's one of them always charges way faster then the other two but discharges normally. Is this a issue if the battery otherwise shows no problems? And secondly, how useful is date coding batteries and can you cover it in a video? Thank you Mooch! 😃
I wouldn’t consider that set married if one cell is acting a lot different than the others. It could be damage or a counterfeit. Consider the two to still be married though and remove that third cell. www.batterybro.com has an 18650 date code lookup tool you can use.
Great vid mooch I’m running two 18350s stacked in the pulse bf and a .5 ohm resistance and the batteries don’t get hot is it safer to run one battery with a lower resistance
Idk if u will see this but I am thinking of getting the clutch x18 which is a parallel mod and up to this point I've been using a single mech and regulated mods so I'm a bit confused. If I put 2 molicel p26a 18650s in rated 25A each and charged to 4.2 volts. If I'm correct that would give me 50A. Then a build at 0.15ohms would that be safe to run. The mod says it can't exceed 37 amps or the fuse will crack. I did check on an Ohm calculator and saw that it comes out to 28A so it should be safe but I'm confused when u explained that one battery would be for example 25A and then u half the 2nd. I'm used to using a mech and I normally go to a .15ohm build and just vape until I feel like the battery is hitting weaker then switch. I just wanna make sure I can do the same thing with the parallel mod. Obv if I have 2 batteries at 50A and a .15ohm build requires 28A on 4.2 volt battery. As the volts decrease the amps required will also decrease. So I'm just wondering if I can safely drain the batteries the same way I would in a mech. Hope u can help and sry if I sound stupid, just wanna make sure I'm being safe.
That Clutch is a full mech so use the same calculations and safety. Cells in parallel don’t share current equally so many people half the rating of the second cell to take that into account…just in case. It’s up to you whether to do that or not. There’s no way anyone can predict how well your cells will share current when new and especially as they age.
so, series-parallel does not matter. does that hold true in unregulated as well when it comes to battery life ? so it would just be watt-hours correct ? for example you run the same wattage on a para, and then the same wattage on a series the battery life will be the same, correct?
Yes, as long as you have accurate wattage calculations...wattage is wattage. You lose a bit of power going through the regulator circuit board, a few percent, though.
Hey Mooch I have a Wismec Gen3 and where the battery door closes the two pins that complete the circuit to the bottom door one of the contact plates is worn through the copper not completely but enough to make it work,I started noticing it misfiring and I figured the mods not safe to use. Should I toss it ?
An improperly working mod is never a good thing to use. I don’t know if its safety is compromised or not so I am forced to err on the side of caution and tell you to not use that mod anymore.
In a HoG (para-series mod) is it useful to "marry" two and two pairs, so the same two always is in paralell? I have two married sets of 4 batteries, one set I have "the flash" wraps on, with two of them wrapped upside down, so the flash don't have to be upside down in the mod. but I ran out of special wrap so the other set is just plain green, with no way of knowing which battery goes witch way...
Hi Mooch, what’s your thoughts on running series 18350’s in the Pulse squonker? I’ve got some Efest Purple 350’s here (no idea what’s under the wrap though) but we’re these rated as 15A cells? They’re got 10.5A printed on the wrap.
Yeah thought that was on the high side, what 18350 would you recommend to run in series? I’ve put a single coil Flat ni80 0.95ohm build in the Drop here to stay safe to see how it is before getting some new 18350’s, coming out to 8.8A and 74w. Nice flavorful vape but want to get some decent 350’s for it. I just don’t trust Efest batteries anymore.
I’ve ordered a pair each of Ampsplus & Keeppower 1200mah 10A batteries now, I think the Mah rating is slightly high and more like 1150 but they look like a good 10A battery. Not a lot out there, most of the popular ones are 5-8A. After a load of reading im pretty sure these use the old Aspire cell under the wrap, also from what I’ve read Vapcell use the same cell in their new 18350? Should be good. I’ve ditched the Efests, getting a little warm after 6-7 pulls so didn’t want to risk it.
I have one question. In an unregulated parallel setup, is there a point where addidng more cells no longer changes outcomes? I see all these homemade boxes at events with 10, 20, or more cells (guessing in parallel) and just wondered if that would offer any benefit at all?
Adding more cells will always increase the current handling (if the wiring and 510 can handle it) and vaping time but at a certain point the returns might not be worth the investment. Sure, 101 cells last longer than using 100 cells but it’s only 1% longer vaping time.
OK Mooch, I've been biting my typing tongue as long as I could waiting for you to start a dialogue about chargers but I can't get an honest/intelligent answer from any of the sources I've poled concerning my 2nd Nitecore New I2 2 bay battery charger. So I will start it.the reason It's my second is that I returned the first one because it heated up when charging batteries. But the second one does the same thing. : average room temp of 68 - 70 degrees, 2 18650 batteries take 5 hours to charge. I'm o.k with that but during the process the charger and batteries reach what I estimate to be about 85 degrees fehrenheight. I'm pretty sure the charging system shuts off when charging is complete because they cool down gradually. Is this normal?
i run below 50w most of the time and im more concern about battery time rather than the amp limit.Which is better, a series double 18650 (drag/charon) or a single 18650 mod but ill be carrying extra battery
It depends on your personal preferences. A dual battery runs longer before needing charging but is heavier. A single battery mod is lighter but won’t run as long.
I say to NOT charge in the mod if series and unregulated. If you have a regulated mod with a battery voltage balancing you can do it. I talk about this in the video.
How does a 3 battery regulated mod work? I have two both use two batteries in one orientation and the third is switched, does it work somewhat like para series?
Thats because when you have the first battery one way, and the second the other way, theres no third way to put the third battery.. (or, there is. but the mod would look stupid)
