Hi
@Baditude.
I too am buying a new box mod and am considering a cuboid. I had considered the rx200 but just bought a D2 charger. So a dual box mod is the road I want to go down.
I'll be using the crown .25 coils which can fire up to 120w but I doubt i'll ever be that high.
Sorry if this is not the right place to ask this but I've read most of your blog enteries on batteries and I'm a little confused.
I found this...
To find the amp draw use
I=P/V (-10%)
Eg.
50w divided by
4.2v equals 11.9 divided by 0.9 =
13.22 amps
50w divided by
3.2v equals 15.6 divided by 0.9 =
17.33 amps
With multi battery devices, simply calculate the amp draw then divide by the number of batteries.
...Going by those calculations even at 120w I worked out that the Samsung 25r batteries with 20A would be fine for my needs.
I then came across this...
Some mods are designed to use two 18650 batteries simultaneously. Series (batteries stacked end to end) will double the voltage output, but the capacity (mah) and amps will stay the same as using only one battery alone. Parallel (side by side) batteries will double the amp and mah capacity while the voltage output remains the same as using single battery.
As far as I'm aware the cuboid runs series even though the batteries are side by side. So does this mean the amperage isn't divided by 2 on the above workings out? Will 2 Samsung 25rs running in series not be safe?
I intend to have a paid of VTC4's in my rotation but wanted a different brand for the other 2 batteries in the rotation and was going to get the 25rs.
It's confused me quite a bit when I finally thought I had grasped a solid understanding of it. I intend to use married batteries, but again for the cuboid is it necessary to alternate the batteries between the left and right holders in the mod after each charge?
Again I apologise for hijacking you post Jacob. New here.
