Single-Use Battery Rework
Currently, Single-Use Batteries aren't really used. To fix this problem, I propose the following changes:
Addition of the Battery Hull
This new item's only use would be being a crafting ingredient. Its addition would also mean that the RE Battery is now created by filling a Battery Hull with Redstone in a Canning Machine.
Changes to the Single-Use Battery itself
Firstly, its texture would be reverted to the old one. Secondly, it wouldn't be crafted anymore, but created in the Canning Machine using fuel cells as input and Battery Hulls as containers, with the result being Battery Hulls filled with 6 cells worth of fuel and containing the EU equivalent of fuel mixed the same way.
Hello, potential costumer!
We heard that people disliked our new T-051 Non-Rechargable Energy Storation Units™. Because of this, we got our plans for the T-501 Non-Rechargable Energy Storation Units™ out again and improved them even further! That's right, they can be IMPROVED EVEN FURTHER! Using our Unmobile Food Canning Machine GTA4™ you can fill T-000 Empty Energy Storation Unit Hulls™ with Octanium C++ Fuel™ or Econium P-- Plant Fuel™ previously contained in a few C-600 Capsule Cell Containers™ to create T-510 Advanced Non-Rechargable Energy Storation Units that contain all the power of the fuel! Of course, they definitely can't be adulterated using light, energy and/or explosives to create some kind of hypothetical super-battery.
