    Just got the new aegis legend. Its sweet and i want to get the best and safest batteries for it. Safety and battery life are my concerns. Right now i have sony vct 5a's. I need some backup/extra batts. I dont know which i should order? Any help or advice would be awesome. Oh, also i use the .2 mesh coils and dont go past 90 watts.

    Thanks,

    Kc

    Samsung 30Q or Sony VTC6 I’d used at that wattage personally...

    While it is true the fact 45W per battery is the recommended overall safety limit for the 30Q and the VTC6, likely you will get mediocre vape performance from these batteries if using them at that wattage. That's just because their internal resistance causes too much voltage sag for a lot of (if not most of) affordable regulated mods to be able to keep up with that so by the time the batteries will be half discharged the performance of the mod itself will often start to suffer noticeably so if you are looking to maximize on safety without sacrificing too much battery life (i.e. run time) you should IMO definitely check out the Samsung 20S (available from IMRbatteries.com). The 20S has a CDR of 30A, whereas the 30Q and VTC6 are only 15A so in pure terms of safety the 20S mops the floor with the latter ones all day and twice on Sunday.

    using them now they work absolutely fine ...

    also why go for 2000mAh cells when there really is no need at 90W?

    The OP said "best and safest" so, because in 18650 the safest = 30A, I have to recommend the best performing 30A battery available to us right now, which is the Samsung 20S. Like I said at 90W with dual 30Qs or dual VTC6s in an affordable regulated mod, the vape performance typically starts to decline long before the voltage cut-off of the mod is attained, as the accuracy of the chip just cannot cope that well with the bigger voltage sag you'll get from these batteries if vaping on them at that wattage. So the mAh rating alone does not reflect the real world vaping time, as the voltage also plays a part, both in terms of how the chip inside the mod reacts to the voltage sag and in terms of the fact that getting less volts also means the regulated mod will increase the amp load in order to sustain the wattage required, thereby discharging the battery faster, i.e. obtaining less mAh from it compared to what you might have anticipated. It means the difference in actual vaping time often tends to be a whole lot smaller than most people would have you believe. Getting a few more pulls at the sacrifice of letting the batteries run warmer causing them to age faster, as well as at the sacrifice of running them at the recommended maximum safety limit instead of running them safer below this maximum limit, proves to be often not really all that smart after all. Way too many people wrongfully assume all regulated mods remain unaffected by the voltage sag of the batteries when it comes to the mod's vape performance. If using the 30Q or VTC6 at their recommended maximum safety limit, you can expect performance will suffer, often to the point where you will regret having bought these batteries after you compare them to 25A batteries. But I'll agree that going for the 30A Samsung 20S might be a bit overkill in terms of the safety, albeit that is for the OP to decide, as a 30A battery is still safer than a 25A one, and that is still regardless of how anyone wants to put it.

    That said, the 30Q and VTC6 already are superseded by newer batteries, i.e. the VTC6A and the Samsung 24S. Similarly, the VTC5D also is better than the VTC5A, and, as we've previously discussed, also can be a wiser choice than the 30Q and VTC6 if you know how to correctly interpret Mooch's constant current discharge graphs (i.e. if you can remember who Alessandro Volta was).

    I see the angle you were coming from with the first line :cheers: agree from a safety aspect you are right

    I dunno caram in the regulated mods I’ve got they both go longer through the day without swapping out certainly over VTC5A, admittedly the 5As hit harder though and is what I always use in mechs or unregulated mods

    Really depends how hard you push them and the OP said he doesnt go past 90W not necessarily at 90W ....I expect it’ll be coil dependant could be anywhere in the range before that.

    The latest cells aren’t all readily available yet certainly where I buy from so haven’t tried them yet

    Of course they both [30Q, VTC6] go longer at that wattage over VTC5A, but not by much so that's my point... you can decide to sacrifice that little bit of extra vaping time by going for the VTC5A. What you'll gain in return is it'll run cooler so it'll age slower (thereby degrading its original capacity slower, which also means eventually it'll start running longer than the other two) especially if you chain vape and or you vape outside under hot weather conditions, and it'll be safer despite extra safety isn't "truly necessary" in this particular instance, as the other two also already meet the recommended safety criterium.

    Out of the 3 newer batteries [VTC5D, VTC6A, 24S] that I also mentioned (aside from that 20S that I mentioned first), I own only the VTC5D, more specifically, the Vapcell rewrap thereof that's the black one labelled 25A 2800mAh and that I had ordered from NKON in The Netherlands a while back. (I live in Belgium so NKON are the best available option for me.) On the mech it hits just as hard as the VTC5A, but runs a tad longer so in a regulated mod you can expect the sacrifice in vaping time compared to the 30Q or VTC6 at that wattage to be even smaller still. That's pretty good news IMO, because the CDR of the VTC5D is 25A, same as the VTC5A.

    Certainly is good news

    What’s the price different of the new cells?

    I paid € 9.25 per piece whereas the VTC5A is now only € 4.99 (or € 4.75 if you buy 10) so there's a hefty price premium with the newer cells, but it's only chump's change in comparison to how much I've been spending on vaping as a whole... I believe the 'D' in VTC5D stands for Dyson, and, my Dyson Pure Cool Desk Purifier (2018 model) has a built-in sensor that, each time after I vape on the VTC5D, reports─in red─my clouds are way too thick so I'm guessing it's a great new cell. :D

    Just a way to cover their tails, as none of the cylindrical cells we use for vaping are designed to be used outside a fully protected battery pack with a protection circuit. But when we vape on these types of batteries we can follow a number of battery safety guidelines to reduce the risk levels in such a way that the risks can be made acceptable despite we can never make them completely safe.

    I suggest VTC5A or Samsung 20S. The 20S pair works for me. I'm having battery hatch issues at the moment with VTC5Ds getting stuck in the snug battery hatch. I would use VTC5As because the VTC5D and 20S batteries actually have larger dimensions, believe it or not.

    The Samsung 20S and VTC5Ds definitely DO pack a bigger punch. I use a Freemax Mesh Pro .15 ohm triple mesh coil at 103W and chainvape. The battery hatch is so tight that the cells are often impossible to remove. While on the topic, does anyone have this issue, and if so, what is the best way to grab them out? Sometimes a single firm shake works and sometimes it seems 2-4 less firm shakes get them out? Tweezers would ruin the entire thing, right? Somebody suggested chopsticks but that doesn't help because the slits are so snug.
