This makes it one of the highest-CDR 18650 cells in the Vapcell range, suited to regulated mods running at higher wattages and sub-ohm builds that draw significant current. Rapid charging at up to 3A, wide operating temperature range, and no BMS protection circuit (standard for vape mod batteries). A serious high-drain cell for retailers serving performance-focused vapers.

font-size: 14px; line-height: 1.7;\"\u003eThe Vapcell U30’s 30A continuous discharge rating places it firmly in the high-drain category of 18650 cells. Most standard 18650 cells are rated at 10–20A CDR — the U30’s 30A CDR (with a 45A max pulse) means it can safely deliver significantly more current without exceeding its thermal limits. This makes it the right choice for regulated mods running at higher wattages where lower-CDR cells would be operating closer to or beyond their safe limits.\u003c\/p\u003e\n\u003ch4 style=\"color: #e65100; margin-top: 15px;\"\u003eWhat Is the Difference Between CDR and Max Pulse Discharge?\u003c\/h4\u003e\n\u003cp style=\"color: #bf360c; font-size: 14px; line-height: 1.7;\"\u003eCDR (Continuous Discharge Rating) is the maximum current a cell can safely deliver on a sustained, continuous basis. Max pulse discharge (45A on the U30) is the maximum current the cell can deliver in short bursts — typically a few seconds. In vaping, the initial firing of a coil often draws a brief pulse of higher current before settling to a sustained draw. The U30’s 45A pulse rating provides additional headroom for this initial spike, reducing stress on the cell during firing.\u003c\/p\u003e\n\u003ch4 style=\"color: #e65100; margin-top: 15px;\"\u003eHow Does the U30 Compare to Other Vapcell 18650 Cells?\u003c\/h4\u003e\n\u003cp style=\"color: #bf360c; font-size: 14px; line-height: 1.7;\"\u003eThe U30 is Vapcell’s highest-drain 18650 option in this range.
