when you buy "More than the max energy" you still get that energy above and beyond your maximum.

EXAMPLE

I have 5 energy, I buy 100 energy, I will now have 105 energy to use.

The down side of it is that your energy will not regenerate until it is less than 5 again, So unless you plan to use that 100 energy in less than 10 minutes, you miss out on the regens so in the "real world" you have purchased slightly less than 100 energy.

I hope you understand what I mean
