In the energy storage blocks, you have the option to change its redstone behavior.
I like to set it to "Emit if full" because then I can make a storage, that has a display of how much energy I have.
The problem is that when I use energy from it, some of the blocks will have 32 EU (for batbox, 128 for MFE and 512 for MFSU.) less than the maximum EU, and therefore not emit a redstone signal.
So my suggestion is that there should either be another option that emits if it is almost full like this, or change the current "Emit if full" to output redstone power if it's 99,9% full.
Please share your thoughts about this!
EDIT: Instead of emitting if 99,9% full, rather emit if the EU supply is larger than or equal to the maximum EU storage minus whatever it emits per tick.
This is 39 968 for batboxes, 599 872 for MFE's and 9 999 488 for MFSU's.
