Depending on how close to the minimum performance edge your RV battery setup is. It's important to remember that a diode has a .7v loss. Loss makes heat, that is why this type of isolator has fins. 

 

 

Came across the  diode one I have in a thrift store for a couple dollars but never installed it.  Been so long I can't remember where it is now.... <gees>

 

Everyone has that "dead coach battery" after winter issue.  Even unplugged, they seem to discharge.

 

I always hook up the coach battery to a low amp charger for a few days before I switch to the AC/DC inverter/charger to top it up before even trying to turn the engine on.  I guess I have been doing the right thing with out knowing.

 

I do think that a "smart" isolator might be in the cards before I head out this year.

Decades ago I  bought a diod type (not sure if that is the right name) isolator to replace my "old school" relay.

 

Since I'm not a "do it for fun" because I'm bored, kind of person, I never got around to swapping and still have the relay on and working fine.

 

Glad I didn't put it in as all things battery have changed a LOT in the 3 decades I've owned my toy house. 

 

This topic has caused me to "rethink" my "it's fine" plan now.

 

So.......

 

Who has one of these smart isolators installed and has it been long enough for a verdict? 

 

Here another I've come across besides Redodo
