I need help choosing the best battery for my new Kanger Subox Mini.

[newbieguy123]

So I just recently ordered a Kanger subox Mini but I forgot to order the battery (the one I wanted was out of stock when I was making my cart so I was gonna add it later but I forgot and they also no longer have this battery). I've got it narrowed down to two choices, but I'm not sure what to make of the amps and mah and what not. The two are below. The two main differences I see is the mah and the amps. So I am wondering is it best to go with a higher MAH and lower AMP or other way around? Also what do these two things do exactly? I have a general idea for mah but I'm not sure. All input is welcome, also if you think I should go with something completely different let me know. Thanks!

I like the Sony VTC4's or Samsung 25R's. I focus more on amps than mah. I have 1600mah batteries I use in a Reo Grand that work fine, but with my setups the continuous amp discharge is more important to me.

 

[Archer74]

its a 50W 0.3 ohm device right? so using the specs to calculate amps says is a 12.9 amp max power requirement @3.8V.

these - for the subox, i would actually go with the samsung 25r, as you won't be going above 50 watts, based on the mod... check out illumn.com, great prices on authentic batteries

Avoid Efest batteries like the plague. Not one of them meets its specs and you can buy genuine Sony, Samsung, or LG batteries for less money.

At 50W max you're only drawing 50W / 3.2V = 15.6A (assuming 3.2V low voltage cutoff in the mod) or less, depending on the mod's max amps specification.

At this level you can use the LG HG2 3000mAh battery and enjoy the longer time between charging. The 25R is a fantastic choice too and will run a bit cooler, but is 2500mAh.

I like the LG HG2s I just got. High amps and capacity

Can you explain to me what exactly a higher or lower AMP rating means for your ecig though?

 

[Mooch]

Can you explain to me what exactly a higher or lower AMP rating means for your ecig though?

Your ecig will draw a certain amount of current from the battery, depending on the coil resistance (if a "mechanical" or unregulated ecig) or depending on the wattage (if a regulated ecig). If the amount of current you are drawing from the battery is higher than the rating of the battery, it can overheat. If you draw too much current you can heat up the battery so much that it "vents", spraying scalding hot liquid inside your device...and maybe on you. And if you go even further, drawing even more current, the battery can go into "thermal runaway" where it can burst, sometimes with flames. If inside an ecig without adequate vent holes this can result in an explosion of the ecig's case due to the high internal pressure from the expanding hot gasses from the battery.

A higher amp rated battery will typically run cooler than a lower amp rated battery, for the same amp level. This not only extends the life of the battery (batteries hate heat), but it helps to ensure that it never gets hot enough to vent, or worse. Higher amp rated batteries also typically run at a higher voltage than lower amp rated batteries, for the same current level. This means that a mechanical ecig will "hit harder", or a regulated ecig won't have to work as hard, to give you the wattage you set it to.

Wattage = Volts * Amps.

If you are wanting 74 watts out of a battery and it is at 3.7 volts, you are going to be drawing 20 amps. MAH is the cell's capacity, and it is rated in milliamp hours. a 3.7v battery with a 2500mah capacity means it should be able to provide 3.7 volts at one amp for 2.5 hours.

Higher MAH means longer runtime between charges. Higher amperage means it can put out more watts at any given time. You can get very high MAH batteries, but the amp rating on them is often very low. At the same time, you can get batteries rated for very high amp discharge rates, but the MAH will be significantly lower.

With vaping, the first thing you should focus on is the amp rating. That is more important than the capacity. If the battery can't supply the amps, it can short out and vent, destroying itself and possibly the mod(and possibly even part of your hand if it isnt a safer chemistry cell).

With the subox mini being able to use 50w and I assume has a 3.2 volt cutoff, that means you will be drawing 15.625 amps at max power with the battery drained. Personally, I like to keep at least a 30% safety margin, so any authentic battery of high quality(not efest) that is rated for 20 amps continuous discharge should work fine for you. Look at the blogs @Mooch has written up on here and find a good quality battery that is rated for at least 20 amps(and preferably one that isn't an efest).

Okay so I think I found a really good battery for a really good price, but I haven't heard of the brand but I am also kinda new to the hobby so I wasn't sure if it was a well respected brand. It is the MXJO 18650 2500mAh 35A Flat Top Battery. If you think this brand isn't that good was thinking the Sony VTC4 18650 2100mAh 30A Flat Top Battery

 

[Mooch]

I've tested that battery. While it's a good 20A battery, MXJO exaggerates their ratings and that threatens our safety. Just my personal opinion.

Buying the VTC4 is a better idea. It's a better battery and you won't be supporting a company that tries to fool us into buying their batteries with false ratings. And you can find the VTC4 selling for less....a win all around!

Hmm....testing all these rewrapped batteries lately is turning me into a battery grouch!

Would you say the same for the 35A?

 

[Mooch]

You mean the 35A rating for the MXJO? It's not true. If pressed, MXJO would say that it's the battery's "pulse rating" but that's a rating that means nothing.

Battery pulse ratings are useless! | E-Cigarette Forum

There are no 18650 batteries with a genuine rating over 30A! | E-Cigarette Forum

In my tests of that MXJO it reaches a crazy high temperature at 25A. At 30A it reaches over 100°C, a dangerously high temp. At this point I stopped the testing as discharging it at 35A could raise the temp high enough to vent the battery.

 

[aznlunatic]

My suggestion would be a couple Samsung 25r's. I bought 4 authentic ones and haven't had a single problem with them and I noticed they hold up better than the MXJO I have not to mention the Samsung never gets warm compared to the MXJO which gets pretty warm after a little bit of chain vaping. I also have a kanger subox mini and the Samsung works great in them. I also heard the Sony VTC4 and VTC5 are great batteries but I heard Sony will stop production on them, so if you were looking to buy them make sure the place you buy them from is reputable and the cells are actually authentic

Oh, after looking at all your testing results and stuff I know now I'd better be careful picking a battery the chart you made is something I'll save so I can make sure if I ever need a new one I reference your work. I'm thinking the SONY VTC5 instead of the 4, good choice?

For the Subox either will be good. They are both good batteries but the VTC4 is a better choice for over 60W.

With the subox only being able to go to 50w, the VTC4 would just be trading off extra capacity for extra safety, would it not? I would think any of the solid 20A batteries would be a good choice, be it the Sony VTC4 or VTC5, the LG HE2, HE4, HG2, or the Samsung 25R. Those all seem like the good choices off the top of my head based on your tests.

Ahhh, darn good point! For the Subox the VTC5 would be a better choice between the two.

Of the 20A batteries I would pick the HG2 first (up to about 60W though) then one of the others. The HE2 falls a bit short of the others in my tests though. Still a decent cell.

 

[nyiddle]

Sony VTC4 or VTC5, the LG HE2, HE4, HG2, or the Samsung 25R

You've definitely got the right idea, just make sure you're buying from a reputable vendor. I like Illumn.com a lot, they haven't done me wrong.
