I recently purchased 2 batteries for a Bolt that I bought, the batteries are, smok ICR18500, 1600mah. I'am new to this type of battery as I have been using Ego's and am wondering if these are "protected" batteries. I'am using the Bolt with standard 510, 2.2 ohm atomizers. Do I need to get another type of battery which would be protected or are these safe with the set-up I'am using ? Thank, himhim
