The Brass Knuckles Vape Pen Battery is designed to use on any 510 Thread and comes in three amazing colors. Wood, Silver, and Gold finish. Its distinctive design matches perfectly the Brass Knuckles vape cartridges. The Brass Knuckles vape mod battery features a 900mAh capacity with variable voltage and Preheat mode. To activate the Preheat mode, the user should click twice the control button which triggers the pen to automatically produce a low power for 15 seconds. This feature is especially beneficial for the thick oils which require preheating in the cold weather. When it comes to the voltage selection option, the LED light indicator informs you about the current one – green is for the 3.2Vm blue 3.7v, and red for 4.3 v. As Brass Knuckles battery works as a basic vape pen battery with variable voltage and single button operation settings, it is as easy to use as possible. Other great features include a child-lock button which should be pressed consecutively five times to be activated and automatic overcharge and short-circuit protection.
