Hey @MC_Overlord12! I'm not sure what you mean by broken battery :(. However, a general tip is that if you see a converter with two different colors, you can draw a wire through it to make a wire of a different color. For example, if a converter is red on the left and yellow on the right, you can draw a wire from a yellow battery to the yellow side, keep drawing through the converter and connect it to another red converter!
