Yes, you can use the same displays as the nuclear control systems. Use an Energy Sensor Kit to right click on the Redstone Energy Cell. That will give you the card from the Kit. Put that card into a Nuclear Information Reader.
I use a computer to read from the Nuclear Information Reader to monitor my energy cell, and turn on a bank of engines when the cell gets below 10% and turns them off when it gets over 95%. Gates would be nice, but the cell never registers as 100% as there is a constant drain. And I don't want the engines running all the time.
