Why?
Makes sense for it to be 1 slot.
And basically everything takes up a 2x2 sections of the grid (or variants thereof), it feels like i'm working with a 5x5.
It also adds some nice variation, and another "something you can get to fill in the gaps".
Total power then becomes 40mj with 2 1x1 batteries compared to the 100mj with 1 1x2 battery, still less than half.
As it is right now, it is a weaksauce 20% of the next level.
Why must it be like this?
Perhaps this might even lead into 3 tiers of batteries, given you already have the art for it. Like the modules.
