You need something that makes more that 3080 EU but a Singleusebatterie (you get 8 per crafting) is only 1000 EU and should be more efficient than a bit Dirt and a bit Tin. So it must be in this Interval:
X >3080
X <1000
So, now you see the mathematical undefined space for adding your Batterie-EU-Balancement
yes i see and do u like this idea?
