Thanks to the wonderful Christina at Heavens Gifts I bring you the Artery Baton Kit with Hive S Tank review. Available in 4 colors Semi-mechanical......Say Whaaaaaat! The Baton Mod That's right people, a semi-mechanical is what Artery likes to call it, basically, you get what the battery gives in volts like a Mech mod but with built-in protections like reverse battery, low voltage, short-circuit.....yada yada yada like most regulated mods except this one you can't control the voltage or wattage output, just press the button and vape on. These kinds of mods have been around for a while but not too many with 21700 and 20700 battery compatibility. They also include a 18650 adapter but whatevs, gimme that good 21700 love baby. For a single 21700 mod it is pretty compact and fits good in the hand. Compared to a couple of my other 21700 mods it is a dainty little fool. Even includes dual LED's on either side of the fire button to show battery status, green is full, then some other color, I think orange then red when it is getting low. LED's only come on when pressing the fire button so no worries of it draining the battery when idle. Easy peasy operation, 5 clicks to turn on or off and press the fire button to get your vape on, that's it folks. Clean looking design with no branding anywhere on the mod aside from the battery cap and the gold plated 510 which has a decent amount of travel. Most of the tanks I tried sat nice and flush aside from a couple with longer 510's had a slight gap which you could see when a light was behind it. Funny thing is the Hive S tank that comes with the kit also has a slight gap. The tapered design is kinda cool, measures 27mm on the bottom and tapers down to 25mm at the 510. The battery cap is great with buttery smooth threading, the only con I had was it is a fine thread so takes a while to screw on and off, nitpicky for sure but I am impatient so notice those kinds of things. The finish has been excellent, not a spot on it even while being in my pocket a few times and taking a tumble in my car when taking a turn way too fast. Performance Since this is a "Semi-Mechanical Mod" I compared it to one of my Hybrid Mech Mods that uses a 21700. The same battery used in both, a Samsung 30T 21700. Right off the bat, I can tell you the Baton mod doesn't hit as hard, must be some voltage sag due to the electronics. Not a huge difference but noticeable and as with all mech mods the power drops as the volts drop. Still, the Baton performed admirably during my use, no real complaints and not once did it give me any trouble during the full month I had it. Not really much else to say performance wise, it just works like most Mechs with added safety features.... let's move on. Battery life and charging Battery life was great with this thing, trying to find the battery cut-off voltage seemed like it took forever. I measured 3.25 volts when I got the blinking red lights on the LED's and the mod stopped firing. Of course, this will all be dependent on your build, for single battery mods I like to use single coil RTA's and they worked like a charm. One thing it has an advantage over true mech is a USB port for pass-through charging on the go. You should always charge your batteries on a charger instead of using a mod but when in a pinch it worked great for me, I can charge in my car and still use it.
