While experimenting with the power diode, I found inconsistencies in its behavior.

Its purpose is to transfer power when the back power graph has a higher percentage of stored energy than the front power graph, but it doesn't actually intend to balance them that way.

For example, a fully charged large battery will transfer 50000 * (1 - 0) / 2 = 25000 energy (clamped to 4000) to a small battery. However, intuitively it should be around 3700.

This code fixes the issue. I also believe that there is no longer any need for the clamp or for dividing by 2, but it remains unchanged.

I think that the battery diode works on total stored power, not percent.
This means the behavior is actually correct.

"Moves battery power in one direction, but only if the other side has less power stored."

Okay, that's possible, but if batteries are switched:

Shouldn't it be 2k and 2k?

Did the small battery get placed first?

And yeah, it definitely is weird. I think it might not activate instantly to stop it (or something).

You could be right about it being broken.
Idk.
