Powered by Critical Core technology and Bluetooth 5.0, the Critical Connect V2 Universal Battery is designed to deliver consistent power and extreme accuracy to enhance the performance of your tattoo machine.

The new battery features a customised jumpstart option that you can switch on and off when required, to help tackle large needle groupings and hard-starting motors.

It also offers more versatility with a magnetic connection, such as the Musotoku Mercury M-1, and an RCA converter making it compatible with a range of rotary machines. The battery is also compatible with the Critical Universal Charging Dock and the Critical Connect Foot Switch, which it can connect to wirelessly.

The sleek, ergonomic design is complemented by a crisp OLED display for precise voltage control. Its lightweight build can provide up to 10+ hours of run time, making it ideal for long tattoo sessions.
