User blog:BadFish95/What is the Max Unit and Item Capacity?

I recently increased both to 500, however, i found out that that isnt the limit, i legitamately want to know the max current limit, i thought it was 50, but is it now 1,000? Can someone post like a short vid or something of someone trying to expand both but get denied? Cause its frustrating  that i legitamately cannot find an asnwer anywhere. Thank you anyone who responds.
