Greetings from
Canada! Welcome to ECF!
I agree with all Stef64 is saying.
The thing for you to keep in mind is, we are only referring to a different (larger) battery than you have now. These are still 510 threaded and you can still use all your goodies on them. Use what you have now and if you feel you would like or need longer battery life you can move to Riva, eGo (regulated at 3.2 - 3.4, I don't want one, either), kGo or any other eGo type battery later.
I use an eGo type 1100 mah (pass-through) battery that charges with a USB cable in the flat end so that I can still vape while it is charging. All of the ones mentioned here are quite inexpensive and you do not need to
buy the complete kit (since you already have a 510 kit and equipment) just the battery part.
It can be as simple as you want or as complicated and expensive as you want. The 24K Gold (Plated) Provari is very nice, but not necessary!
