This will be my first mod I am wondering, can I use a 510LR with the 5 volt ? Or is that too much. I love the LR's maybe I should go with the 3.7.
No its not advised to use lr with 5 volt...it will kill the atty fast. I myself will always recommend the 3.7volt over the 5 volt.
One: There is less to go wrong with a 3.7 volt. mod because you don't need to run a voltage regulator.
Two: I think the flavor is better with 3.7 volt
Third: You are not wasting battery life with a 3.7 volt., the 5 volt is still using the whole 7.4 volts, it just wastes the 2.4 volts by turning it to heat, thats why I need to use a heat sink on the 5 volt.
Forth: I love to take long drags and with a 5 volt if you take to long of a drag you get a burnt taste.
And Lastly: It is my experance that you can get a better vape using a lr atty or carts with a 3.7 volt.
