Cole-Hersee makes a heavy duty battery switch that we used on our Fire apparatus.  It has a separate connection for each battey positve cable as well as an "power out" connection.  Switch can be set for BATT 1, BATT 2, ALL, or OFF.  Jack

Just a note on My batteries.  When I get back from arcadia I will have a method of disconnecting each battery in My house battery bank for sure.  Waiting for a meltdown to cease is beyond dangerous.  When I discovered the fumes from a shorted boiling battery there was no way to disconnect the other seven batteries for fear of an explosion.  Not sure just how I am going to accomplish this yet.  John

Trust me while your at Arcadia you will have many example to look at! Once you find the one you like ask the owner questions and where to get this and that and you'll have it made!  FWIW ;D  BK  ;D

Junkman,

I agree, separate disconnects are the only really safe way to go.

I use "green knob" disconnects from WM, JCW or your local farm store for aroung $5-7 which clamp onto a battery post.

The only problem I ever had is with the knobs sometimes vibrating closed when I had them off. The solution to this is heavy rubber bands!

Also, don't put a lot of down pressure on the battery cable at the clamp when the disconnects are off because they are a bit weak when open.

I always carry a spare or two just in case but have never had one fail on the bus.

Be sure you get hardware that is properly rated...

How much amperage is passing through each of these, and is the hardware sufficient?

You may find there is an economic reason why there are not numerous battery cut-off switches employed in other set-ups.

happy coaching!
