Diode for Battery Bank Merge Solenoid

[Red Rider]

I ganged three ,300 Amp golf cart solenoids on a buss bar .Seems to be doing just fine however I'd need to run that set up for several years like some of you have to see if it will really lasts. If I had to do it over gain I'd get a "Smart Solenoid" (Google) that takes out all the guess work and the "oops I forgot the switch" out of the equation.

What's draining your batts that you need this so often?  Should be looking at that problem first.
