Some way to branch out power based on a programmable percentage of the input rather than a set number. Either a new item or an additional option on the existing electrical branch. Would be very useful for charging multiple batteries that have different loads off of the same power source.
Currently I need to evenly split power with splitters or use a chain of branches which makes the first branches in the chain take priority during low power generation, resulting in those batteries charging perfectly fine while the others get no power at all. If I could branch out power by percentage rather than set units the batteries could all charge and drain at the same rate.
