The Brass Knuckles pen is a vape pen battery for dab carts and matches the appearance and design of the Brass Knuckles vape cartridges. The Brass Knuckles pen battery for cart features preheat mode and variable voltage with a capacity of 900mAh. Moreover, unlike other vape pen batteries, the Brass Knuckles pen recharges with a convenient pass-through Micro-USB charger.

Brass Knuckles Pen Design

To perfectly suit the Brass Knuckles cartridges, the top tip of the Brass Knuckles battery features a polished brass finish and measures 10mm in diameter. For the best connection with most of the vape cartidges, the 510 thread connections feature a push-pin.

Brass Knuckles Battery Voltage

The Brass Knuckles pen battery employs a power button with an integrated LED indicator and multi-colors light. The LED changes the colors according to the selected voltage settings, and the Brass Knuckles pen operates with a single button. The power level modifies with three consecutive clicks on the control button; the battery raises the power in one of the three setting options; green light 3.2V, blue light 3.7V, and red light 4.2V.

Brass Knuckles Preheat Mode

To activate a preheat mode, click twice the control button, and the pen automatically produces a low power for fifteen seconds before turning off. During this time, the Brass Knuckles pen battery has 2.0V, and the coil generates low heat to warm up the oil before vaping. That's a convenient feature, especially in cold weather when the oil is super thick. The preheat mode cancels with a single click at any time.  

Brass Knuckles Pen Child-Lock Button

To lock the battery from accidental firing, press the power button consecutive five times, and the battery turns off. To turn the battery on, press the power button five consecutive times again. Once the power is on, the LED light button flashes three short times, confirming that it's ready to be used.

Brass Knuckles Charging

Includes 510-USB charger connects to the top of the battery and recharges from the AC/USB adapter with a maximum output of 5V/500mA. The LED light flashes three times, notifying that it's successfully connected and stays red while charging. Once the charger completes, it automatically goes off, and the LED light changes to the green light.

Brass Knuckles Pen Safety Protections

Along with the overcharge protection, the Brass Knuckles battery for dab carts guards with the over-discharge protection that turns the battery off when the battery voltage drops below 2.4V. Moreover, the Brass Knuckles pen battery has a short-circuit and overtime protections that turns the battery off if the vaping session is more extended than twelve seconds; then, press and hold the power button again for another vaping session.
