Hi all so i finally got me a temp device, love it so far. But what would be a good battery(s) to get the most power and long lasting battery life. Right now i have a samsung inr 18650-25-R in my device works well drains quickly, i'm currently running in normal power mode ( haven't picked nickel coils for my sub mini yet) at about 40 to 45 watts. my coil reads are at a steady 0.60 ohms so what do ya recommend. any and all info much appreciated.
thanks all
