510 Thread Battery - Flat Edition

Yocan 510 Thread Battery - Flat Edition The Yocan Flat is a 510-thread battery built for concentrate cartridges. Its defining feature is the square profile: four flat sides replace the round barrel you'll find on most 510 batteries, which means it sits stable on a flat surface instead of rolling off and keeps a more secure grip in your hand. The body is aluminum with a rubberized outer coating. That combination keeps the weight down while giving the shell real resistance to everyday wear, and the rubber finish adds friction where a bare aluminum tube would feel slippery. The square power button on the upper face cycles through the variable voltage settings and also activates the preheat function. A 15-second auto-cutoff is built in. Charging is USB-C. At 650mAh, the battery capacity sits in the solid mid-range for a 510 pen battery. This is a single-unit retail listing; the source references a retail display of 20 units, so stock availability reflects that format. Specs Connection: 510-thread Battery capacity: 650mAh Voltage: variable, toggled via power button Preheat: yes Safety cutoff: 15 seconds Charging: USB Type-C Body material: aluminum with rubberized coating Shape: square profile Intended use: concentrate cartridges Good to know No charger is included; you'll need your own USB-C cable and power source. The square shape prevents the battery from rolling on flat surfaces, which round-barrel 510 batteries are prone to doing. Variable voltage and preheat are both controlled through the single power button, so there's no separate switch to manage. The rubberized coating improves grip compared to bare aluminum but may show wear over time with heavy handling.
