I was worrying a bit about whether I might overload my Moli 10A batteries. Found a website called RapidTables that does the calculations for you.
Turns out with a 1ohm coil you could set the mod to 100 watts before you hit 10A draw on the battery. You do hit the limit quite fast with lower resistance coils.
I ran the numbers through the calculator and never went over 4 amps for any of my setups, which is reassuring. That's a useful web site.
While RapidTables is okay for very basic information on watts/volts/amps/ohms it doesn't inform us what our batteries are doing.
Basically, it's useless for helping us to understand how our batteries function.
A much better, vape related, website for determining your battery drain is Steam-Engine. It was created for vapers by vapers.
Battery drain calculator for APVs/mech mods. Returns amp drain, power drain, amp limit headroom, run time, estimated number of puffs, etc.

Visit the page and enter the coil data for your RBA and the specific details for your battery and the battery drain tool will show you all the details you might want to know.
Scroll to the bottom of the page for very detailed explanations for each section.
Are you using the Molicel M35 18650 3500 mAh 10A?
I entered the data you provided, see the attached screenshot.
ETA: The battery drain page does not have an 18650 battery preset for a Molicel 10A. There are other 10A batteries in the list. Choose one of those.
