Would I be able to use for let's say, a 30 amp battery. If I use 2 of those. Would it still mean a max of 30 amp? Or would it slightly increase though. And yeah, I probably shouldn't be pushing these batteries even close to the max, I've been vaping at 120 Watts the whole time. Untill I got this new tank
Like I said, the amps on the display screen is useless, it tells you nothing relating to battery safety.

Calculating battery current draw for a regulated mod | E-Cigarette Forum
The above is a basic explanation.
I have power devices that discharge cells down to 2.8v and some that cut off as high as 3.4v.
Because of this I use 2.8v as the low voltage cut off when calculating amp demand, most folks feel comfortable using 3v or 3.2v, whatever they
know their 'mod' discharges cells down to.
A good 'safe' rule of thumb is;
15a CDR 45w
per cell
20a CDR 60w
per cell
25a CDR 75w
per cell
30a CDR 90w
per cell
But,
only when using authentic cells bought only from
known reputable dealers in a decent regulated power device
.
So if you have a decent regulated power device using 2 authentic 15a CDR cells = 90w
2 authentic 30a CDR cells used in a decent dual cell power device = 180w.
The batteries must be equal/matched when used in a multi cell power device, same brand, same mah, same CDR, bought as sets, used as sets, charged as sets.
