I think your best bet would be to find a local B&M where you can look at some ego-c twist type batteries(Variable volt), that would allow you to adjust the voltage to suit you for taste, and throat hit. A good shop can lead you in the right direction. Just take what you have with you, and explain what you need. Good luck.
Just don't let them push you into some crazy mod with a rebuildable topper. That can come later.
+1 on an "Ego type" of battery like a Vision Spinner. You could also look at the MVP v2. It is a step-up from an "Ego style" battery in that it has a huge battery (can be vaped on while charging) and is variable voltage/wattage.
