Just in the other day, these were on sale over at Vaperz Cloud and had an impulse moment. I saw the Ultem model last year on line and was impressed by the look of the mod. I was not aware they had several other models as well and found the Iced Out was in stock and on sale for $75, so I picked it up. This is the first dual 21700 serial mech mod I have procured but not the first serial mod I have owned as I bought the Wismec Noisy Cricket designed by Jaybo back in 2016 for $40.
For those of you that are not familiar with a serial configuration, it is basically two batteries stacked on top of each other. You get 8.4 Volts (3.7V x 2) and about the same mAh as one battery. Parallel configurations, two batteries side by side, give you the same Voltage output 3.7V but twice the mAh. Most dual, triple and quad battery mods are set up in parallel.
Some mods like the Noisy Cricket give you both a Serial and Parallel connection providing you flexibility. It does this by changing the physical configuration on the bottom battery connections. There are some other mech mods that can do this like the Hammer of God but I am not personally familiar with them at this time.
It has been years since I built coils for a high voltage situation and had to review some you tube videos. I found Richard Vick’s video quite helpful also made in 2016.
Basically, I had to build a dual coil RDA to about .7 to 1 ohm which means I had to build each coil to about 1.4 ohm’s to 2 ohm’s.
I wanted more flavor than a single wire can provide so after about 4 attempts to get it right without too much fast heat I dug out/found some simple 26ga x 32ga Kanthal Clapton wire made by GeekVape that worked well and ended up using the Vaperz Cloud Asgard Mini RDA.
I was able to achieve .909 ohms with 12 wraps of each coil to get them to around 2 ohm’s each. As Richard stated, Kanthal has a higher resistance than stainless steel which I usually build with. The lower ohm builds prior to this one I found to be just too hot too fast and so a just slight push of the fire button to get totally blown out. I have a little more time with this build to heat the coils to a heat level that is more comfortable for me.
I love the aesthetic look of the SAGA. It is well made and feels nice in the hand because of the shape of the mod. All the connections are silver plated for better connectivity and less resistance. The center pin is adjustable for use with different rda’s center pin lengths. The switch feels solid and had a good resistance to the push and has room to feel the heat (not just on and off). The Acrylic is thick and solid. Ultem is stronger but it was out of stock and more expensive as well. This page explains the differences between Acrylic and Ultem plastic.
All in all, I can recommend the SAGA if you want something different and feel comfortable working with the high voltage it puts out quickly.
