Issue description:

This cause my GTCE <-> FE bridge to fail with Mekanism since machines (for balance) accept only certain minimal amount of FE at once, below that point they won't accept anything

Honestly I feel that there could be implementation quirks for any value we simulate. I'd rather leave our implementation as-is.

While unfortunate for your case, it is technically correct. Have a look at the reference implementation at net.minecraftforge.energy.EnergyStorage#canReceive - it only checks if it allows any receiving.

I don't see a reason why we can't simulate Integer.MAX_VALUE though, which in theory should solve your implementation quirk
