Best value power supplies imo short of making your own are the Maxamps 12v and 24v, outstanding value. Fans are a little loud but they are nice.
Best chargers out there period are hyperion, there are no better. They cost more but are worth every penny. The newest duo has retard power but consider your packs, you can get a lower duo model if you don't need to charge 7s at over 1000watts or 7s x2 up to 20amps per side
