I haven't got the mod in my hand yet but i purchased an ipv4 and as of right now i have 50/50 juice
An IPV4 is considered a "high-wattage regulated box mod". That doesn't mean you have to use all that extra wattage, but its there is you need it. I'm glad you chose a regulated mod over a mechanical mod as your first device; it will have protection circuitry to help keep you out of trouble as a beginner. Your mod will refuse to fire your coil if what you request is against Ohm's Law and provide an error message to alert you why your request was refused. A mechanical mod would not do that.
You could put nearly any juice delivery device on your IPV4: clearomizer, cartotank, or rebuildable.
Proper Terminology: Juice Delivery Devices
You don't actually buy "ohms". Ohm is the specification of resistance of the wire
coil that your juice delivery devices uses. What ohm coil you choose to use on your IPV4 will depend upon the type of juice delivery device you are using. For example, you buy lightbulbs with a specification of "watts".
Clearomizers and cartotanks typically use "normal resistance" coils in the range of 1.5 - 3.0 ohms.
With "rebuildables" (you make your own coils and wicks), it can be anywhere between 3.0 ohms all the way down to 0.3 ohms. It just depends upon what you will eventually decide what YOU like after experiencing it. Some people like a very warm vape (lower resistance) and others like a more cool vape (standard or higher resistance).
Should you go the rebuildable route, I always suggest starting out making an overall resistance of 1.0 ohms until you get some experience under your belt. Then, should you decide to experience "sub-ohm", work your way down.
Information Resources for Your First RBA
What batteries did you choose to use in your IPV4? They should be IMR or high drain batteries with at least 20 amps continuous discharge rate.
