Electrical new item similar to Blocker and Electrical Branch

The question why Electrical Branch is not connecting to Root Combiner? It should connect to be able make more circuits.
And new item, add new electrical item like Electrrical Branch what passes throu ammount of electricity what you put, but when it lower than that number it blocks circuit, ex.: i need 110 power from windmills and when it less than 110 (not 0) the circuit blocks and passes throw circuit from batterys.
And fix already batterys, i made test what i send 300+ power from windmills directly to batterys and from there i powered 10 turrets and 10 Electrrical Branches (110 power), it discharges faster than charges.
