Battery question

[Spendy]

Hey,

I just wanted to ask if the setup I am using is safe for my batteries?

I use a Minikin v2 and I use 2 tanks a goblin mini with a dual coil .28ohm build and a griffin 25 dual coil with .17ohm build.

I use two types of batteries Samsung 25R Green and Sony VCT4s

I usually vape the goblin mini at 40W and the griffin about 60-70W

I use a Nitecore D2 charger and always keep them paired when charging and never keep the batteries loose always in the mod or in a plastic box.

If anyone could tell me if its safe the setup I am using

Thanks,

Spendy

they're not the same.. personally I wouldn't. if they were the same all around as in amps, mah etc ... they should probably match in that at least and yours don't.

 

[Eskie]

As long as you're pairing the Samsung 25Rs together and the Sony VCT4s together you should be fine. I would not make mixed sets of 25R and VTC4s.

eskie said it better

 

[NealBJr]

What eskie said... just as long as you properly marry the same brand/type/newness batteries together, there should be no problem with the setups. I use almost identical setups.. griffin 22mm I have on my Smok Guardian III epipe running 2.4 ohm 40W with a lone Sony VTC4 (VTC 4's are my single battery solution), and my Goblin V2 running at .34 ohm on either a Cloupor Mini plus 50w running at 35W, again using a Single Sony VTC4, or in the Cuboid using Samsung 25Rs married pairs, or LG HE4's (married).

the ohms your using shouldn't be a problem if you're using it in a dual battery setup and in a regulated mod. I use a nitecore I4, but the D2 is just as good, albeit a smaller brother. The only issue is with the proper marrying of the batteries... which means you bought them together, and keep them together all the time.

bleh that's what I was trying to say in my pre-morning coffee way... using either or of the two types of batteries is fine, but don't mix and match them as individual batteries in the same mod at the same time, even if bought together since they don't match stats.

 

[NealBJr]

Oh yea,

Lol.. I had to pull off that response without coffee.... I am not a coffee person. I kinda wish I was though.

I have a Nitecore D2 charger too... is it okay to only charge one battery at a time or should I always have 2 on there? I have been just doing one at a time but I seem to remember reading somewhere that you should always pair them???

If you're using a dual battery (or triple) mod, the batteries needs to be charged together at all times, so that they have the closest possible output and life. This is what's called a "married" set. Lithium batteries will start balancing out once removed from a charger, but will start to lose a bit of their capacity just by sitting there for a while. So if you charge one at a time, then the next, by the time the second (or third) battery is ready, the previous ones that were sitting there will not be at the same level of the just-charged one.

If you're using a single battery mod, then it doesn't matter.

Although your statements are technically correct, @Imfallen_Angel, I sometimes believe we overthink this "marrying batteries" routine to an OCD level.

While its probably true that if you charge a married pair of batteries separately one after another, but don't use them right away, the one that was charged first will start to "balance out" ... as you put it. I seriously doubt there would be more than 0.2 volts difference between the two batteries of that married set, which is a negligible difference for all intents and purposes IMHO.

On the other hand, why would one decide to charge the batteries separately in the first place unless all you had available was a single-bay charger? This is the only situation that I could rationalize charging the batteries separately. If this is the situation, I recommend upgrading to at least a 2-bay charger.

I do agree to an extent, my comment was towards leaving a battery aside for a fair amount of time... they can differ by quite a bit, especially with some batteries that have some wear, and while some mods have better chips that can accommodate for it, in series, it's very important to not have batteries that differ at much as possible, lithium cells are quite sensitive due the the output they have. I have multiple batteries and once charged, I take them out, put them in silicone sleeves so to rotate them properly...

Note that it's not only voltage that you need to consider, I can give you 2 batteries that with state being 4.11V each, BUT the Ampere output might be quite different due to different usage on them. So, they'll look to be "equal" at first but once you start using them, one could drop dangerously low after a few uses, and that could result in an overload in one of them.

Lithium batteries, for example should not be used directly from the charger, they should have at least a 15 minute cool down to stabilize them, something that many don't even know.

My comment is towards safety, as if you do have batteries that are getting a bit old, the discharge rate could be enough to have an unbalance load hitting them if someone was to charge one during the evening, then put in the second one overnight.

I believe that most are "OCD" with batteries is because of the absolute respect one should have with lithium batteries. In other words, if there's a single doubt about one battery, to not take any chance with it, which I absolutely support.

Well said. Safety should always be our number one priority with battery use.

Thanks, and I do agree with people should get a 2 or 4 battery charger, I don't even understand the point of a single battery charger.

Heck, if Nitecore did an 8 battery charger, I'd get one just to have the extra capacity should I need it, heck I have 2 8-bay chargers for my regular AA-AA batteries, and they are always full (I have lots of devices that require batteries) as they switch to maintenance trickle mode once the batteries are charges.

The only other thing I can think of, is something that may affect the batteries in the long run. I have a nitecore I4, and it has four bays, BUT it has two power channels. Each channel has 1000MaH to charge both batteries with. Bay 1&3 has 1000MaH to use, and Bay 2&4 has 1000MaH to use. That means, when I want to charge my three battery Releaux, If I just charge three batteries, the ones in slots 1&3 will charge at 500MaH, and the one in slot 2 will charge at 1000MaH. I try to always have a single battery that's low to charge with them so I fully populate the charger.

Same thing with two battery mods.... I try to charge in even sets, and I put the two married pairs in the same channel so they charge evenly. I know it seems a bit OCD, but charging at different speeds will eventually mean they drain differently. It might not be that much at first, but over time, it could ruin both batteries.

 

[ceeceeisme]

Thank you everyone! That clarifies things for me. I have a 2-bay charger but only single battery mods so I am okay. And I know about "resting" your batteries before using them - I wait at least an hour before putting a freshly charged battery in one of my mods.

Yeah, I use a Nitecore i4 charger also. When I charge three married batteries simultaneously, the battery in bay 2 always finishes charging before bays 1 & 3. Although the i4 is advertised to have 4 bay independent charging, I suspect that's not the case from these findings.

 

[Cheallaigh]

that is the default charging setup with almost all chargers despite claims

 

[Eskie]

On my Nitecore D4, it will charge 1 or 2 batteries at 750 mAh, 3 or 4 375 mAh, always the same across batteries. Granted, that's slow, but it is consistent. I'm surprised the I4 would act differently.

 

[gotch23]

Yeah, my I4 also does what Baditude and NealBJr said.
My approach is to rotate the batteries that go into the middle position.

 

[daviedog]

At least Xtar states 2 power rails into 4 bays,,resulting in various current permutations.
I'm pretty sure only the Opus has 4 discreet bays in the under 100$ class
