Cuboid - not getting full 200w

[shaunnadan]

hi everyone

i decided to post this here after getting a few pm's regarding battery safety and with the growing number of people interested in getting a cuboid mod.

the cuboid mod has a built in safety feature of a 25A limit.

what this means is that it will limit your maximum wattage output that you can safely fire at depending on the resistance of the coil (this does not affect TC)

this is irrespective of the battery used but it is always recommended that you use safe batteries.

what exactly does this mean ???

your 200w mod will fire at 200w if your coil resistance is 0.36ohm
your 200w mod will fire at 168w if your coil resistance is 0.27ohm
your 200w mod will fire at 155w if your coil resistance is 0.52ohm
your 200w mod will fire at 112w if your coil resistance is 0.18ohm

does this mean its broken ???

NO.

the amount of amp draw to fire those coils will be more than 2x 18650 batteries can handle, and the box calculates that and in tern limits our output power to a safe value.

I presume this is the case with most dual regulated mods in any case. One can do the calculations here to find the spot you want - see they are a bit behind with the listing of mods though.

i think more the newer and smarter mods to be exact.

iv'e seen a snowwolf fire a dangerous build that the sigelei 150 refused to even with the same batteries and the snowwolf got extremely warm. i didn't push the limits to see what would happen though.

Interesting, thank you for the post.
Its like a mech mod stuck in reverse...with buttons
I wonder how long one could vape at 200w?

200w is for big cloud chasing builds - average around 4-5 seconds and maybe 2 hits before its dry if you have enough cotton.

today was dripper mode only for me :

the rx200 had the velocity mini at 110w
the dna200 had the twisted messes at 170w

Lets also not forget the underlying reality of the situation. You're asking 18650 batteries to deliver 100W a piece, sure they may, but for like 5-10 hits max. Also 100W equates to over 26A in discharge current per battery. Dual 18650 mods, really shouldn't be touted as 200W, its dangerous.

and that's why i will always stand by my 11.1v...

Yep 17.62A per cell is well within the safety margins of most batteries vapers use. also low enough not to hurt the long term performance of the batteries.

*edit, its past my bedtime, and this post is utter nonsense 17.62A definitely will hurt the longevity of the batteries, but not as badly as is the case with a dual 18650 mod

what batteries are you using in your mod? would you use a 20A battery (semi-decent headway)

I'm using LG HE4's(25A) at the moment. But ye I'd feel comfy slatting 3 turds in there.

Also you have to think, really how often are you at 200W? I'm usually at 65-85W anything higher kills battery life too much

With my current usage I ask my batteries for a few ms of 17.62A but 99% of the time its 7.41A which is so low, that I may end up getting more cycles than the manufacturer claims I will.

It's something I think a lot of vapers aren't aware of, even with a 25A rated cell, if you run it consistently over 15A it will give you less cycles than the manufacturer claims. The further past 15A you go, the worse the story becomes.

I forget which battery I was reading this about (Possibly smurfs) but the manufacturer was promising 300 cycles, but some guys did some tests at 15A, and they only got like 120 cycles out of it before 40% of its capacity was permanently lost.

Kinda like the underclocking logic with computers, the cooler you keep the components the longer they last, except in this case its more along the lines of keeping the stress levels low... hmm... Thats kinda like people too

But the real question... Would I run Samsung 30Q's in it, answer is... not until I've seen more info about them, and they've had more real world use... By other people, far away from populated areas.
