I've been using RYOBI 18/40V tool batteries to make powerstations. When putting batteries in parallel I currently have to make sure I'm using similar batteries (Ah) with equal charges. I don't want a huge rush of current from a fully charged battery to an empty battery. I noticed they make high voltage/high current Blocking Diodes. Has anyone used these? One concern I have is what will be the available current for the load. If I have two batteries. One full, One half-empty. Each has the blocking diode between the battery + and the load. If each battery can provide 10A of power, what will the available current be for the load? I ordered some diodes for an experiment... but thought someone might already know the answer. Thanks!
