How Much Current Is available in Series-Connected Batteries?
Each cell in series has to provide the full output current, so, if the maximum allowed current for one cell is 2A, then for a string of cells in series, the maximum current will be 2A. The capacity (Ah) will also be the same as for a single cell.

The output of the Arduino is 5v. I''m comparing it to a strand of fairy lights I have which take 4xAA Batteries, for a total of 6V. I''ve read the following: A white LED needs about 3V to operate, and requites around 20mA of current to have decent brightness. Each pin of the Arudino can only output safely 20 or 30mA.

Contact UsWhat Current Does a Battery Produce? (AC Or DC Current)
How Much Current is in a Battery? A battery is a device that stores electrical energy and converts it into direct current (DC). The amount of current in a battery depends on the type of battery, its size, and its age. A AA battery typically has about 2.5 amps of current, while a 9-volt battery has about 8.4 amps of current. ...

For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.

Contact UsEverything about LEDs: Basics of High Power LED Lighting
Why drive current matters… The amount of light (Lumens) an LED emits depends on how much current is supplied. Current is measured in milliamps (mA) or amps (A). High-power LEDs can take currents from 350mA to 3000mA. LEDs vary on their current ratings so be sure to keep track of this when picking an LED and driver. Determining the Brightness

The $ V = I cdot R$ "thingy", as you call it is Ohm''s Law.A very important one. LEDs cause a pretty constant drop which, like Malife says, depends mainly on the LED''s color, and also varies a bit with current.This chart shows you that all visible light LEDs require at least 1.8V. A red LED will drop about 2.2V, so like you saw it can be powered from a 3V battery.
