To those of you who are curious about the new no name battery brand Imren, I just wanted everyone to know that they actually are high quality cell batteries. My local vapor shop sells them, and I personally tried one. They don't have the highest MaH rating, but they do have a true 40A continuous crank. Unlike the vamped brand batteries, which are 20A cont. 40A pulsing, these batteries are true 40A batteries. They have solid cells and hold up well in sub-ohm vaping. Happy vaping!
