I currently bought a segelei kaos spectrum mod. It obviously requires 18650 batteries. I'm going to use my cloud beast tank with TF V8 q4 .15 ohm coils. I was wondering what some opinions were on best brand battery out of Lg/Sony/Samsung was. I currently have several of the Lg HG2 INR 20A 3000mah batteries but that's the only ones I have so was curious what everyone's thoughts were on what they use or think is best for my set up. Thanks so much!
