Alas, I apparently did not research thoroughly enough the battery captioned in the title line above prior to my purchase. It seems that not only are the Ultrafire XSL 18350 batteries "unprotected" but they lack "safe chemistry" as well. I have attached the link to the exact product Amazon.com: UltraFire 18350 3.7V 1200mAh Rechargeable Batteries Battery (Pair): Electronics Therefore, I have a few questions regarding safety 1. Am I right in my understanding that the batteries are neither "unprotected" nor possesses "safe chemistry"? 2. Can the product be used in a safe manner in a Variable Voltage/Variable Wattage device? 3. Can the product be used in a safe manner in a mechanical mod using an atomizer with an ohm rating of say .7 - 2.5? I generally don't go below nor above the aforementioned range Thanks a lot. I would hate to not use the batteries in the event it turns out there is nothing to worry about (above and beyond the standard safety issues any battery possesses.
