I got vapecell’s 26650 battery from a top vendor and the wrap was to thick. Would not let me close door on 1 device and got stuck in another and I had to take the device apart. I’m not sure if the wraps on 18650 are normal but, I’m never buying this brand again. It must be a good profit battery since It was pushed on me from site. I buy and it’s useless. First experiences matter for me.
