So I decided to go very ahistorical and build up my fleet. That is until the game won't let me produce more that two battleship units at a time.
Are there nation specific limits or am I missing something fundamental to ship building (I have all the requisite supply of commodities)?
Every nation has a force pool of units it can build, and that's how the game manages to prevent players from doing completely ahistorical things like the one you said you want...

BUT, you can always turn on the expanded pools (and in your case you should also turn off the historical SOIs to have your colonies to not penalize your VP) and build as many battleships, dreadnoughts, artillery, nukes and whatever you want with the nation you want...
