Issue Description:

Hello, so i was experimenting on the configs for the EnderIO capacitor banks and when you set any capacitor bank value to its maximum, 2,000,000,000 for the I/O rate, and place multiple of the in a multiblock the transfer limit goes into the negatives.

What happens:

What you expected to happen:

I expected it to just combine the energy rates.

Steps to reproduce:

1. Enter a new world
2. Set I/O rate in the configs for any capacitor bank to 2,000,000,000
3. Place multiple of them in a multiblock
4. Look at the GUI and see that the max input/output is negative
   ...

I'll have a look if there's an easy way to limit this.

Oh, code to protect against this case already is in place. I just tweaked it a bit to actually work... ;/
