This is perhaps the most widely recognized battery on the market for THC oil. This battery has an output of 3.7 volts which will suffice for 1.7 ohm and higher resistance cartomizers. Now with the lower resistance cartomizers you might need a stronger battery with a higher voltage output. That's when the Serenity 400 comes to play. You may want to check it out. This is a button less battery, Just suck. You can use the stylus for your phone or tablet. At 18gms and with 510 threads it’s a great deal.
