How long do the Sony 18650VTC4 30A batteries last and how many will I need to make it through a day of chain vaping?

I'm going to order a few online, and want to know how many I need to last me a full day of moderate-chain vaping without recharging. I usually run a dripper with dual coils at about .4-.5 ohms, and go through about 3-5 ml a day.

I run my dual coil Trident at ~0.6 ohms and vape about 3-5 ml. Two VTC4s do it for me. I swap at around 3.7 - 3.8V.
