Installation:
Put Bottlecaps.txt, Grenades.txt, Explosives.txt, Mines.txt, Grenades.txt, Fusion_Core.txt and Ammunition.txt in your Fallout 4 main folder which is usually located in: C:\Program Files (x86)\Steam\steamapps\common

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
How to use:
When in game, open the console (~) and type in "bat [bat file]", for example "bat Fusion_Core"

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

List of bat files and what they do:

Ammuniton - Gives 1000 of each type of ammunition (exluding fusion cores, mini nukes and missiles).

Bottlecaps - Gives you 1000 bottlecaps.

Explosives - Gives you 10 mini nukes and missiles.

Fusion_Core - Gives you 1 fusion core.

Grenades - Gives you 10 of each throwable (excluding homing beacon and institute beacon)

Mines - Gives you 10 of each mine

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

You can change the amount of items the bat files by opening them by changing the number that comes after "player.additem [item id]".
For example if you want the Fusion_core bat to give you 10 fusion cores you edit the text file so it looks like this (Before and after)
BEFORE:                                    AFTER:

player.additem 00075fe4 1          player.additem 00075fe4 10
