I picked up one of these. hopefully i can use it rather than a battery isolator. looks pretty sturdy too

John,
i was thinking the same thing, good to jump the coach batteries with the house batteries in a pinch, and to control charging. i will post better pictures of it when it arrives

just as to can tie cord and house batteries together for charging, you could use the house batteries to start if for some reason the coach batteries die. you could also choose to only charge house or only choose coach. prehaps this might help

Looks like a good switch. Ive seen them on there and always wondered how well they will work out. Im not there yet but let us know how they work out. Might be worth getting and sitting till im ready to install.

You've got four settings. Say 1 is starting battery. 2 is your house batteries. 0 is off. 1+2 is both batteries. If you have a dead starting battery, you would switch from 1 to 1+2 and use both batteries to start your bus. I don't know if I explained that well enough. The reason for that switch on a boat is to always have a second battery as backup so you can get home.

I've been thinking of getting one of these as well. My intention would be to use my alternator to charge my house batteries while driving down the road. I assume if I set the switch to connect both sets of batteries (chassis and house) that the charge from the alternator would go equally to both sets of batteries? Or would the charge go first to the batteries with the lowest charge? I'm thinking I could get a gauge to monitor my chassis battery so I would only send the charge to the house batteries if I knew the chassis batteries were full. Am I making any sense at all?

I actually have the blue-sea systems "add a battery" kit. It includes a red rotary 3 position switch. The positions are "Off", "On", and "1+2", the latter being labelled Emergency. It bridges the starting batteries and the house batteries together.

The other component of the add-a-battery system is the isolating/combiner. When either side of the combiner is showing above 13.x volts, it combines the house and the vehicle systems so that whatever your charging source (engine, when underway, or shore/gen power when moored) is charging the whole vehicle.

Great system. I am super impressed with Blue Sea products. (I also have thier fuse block and one of their 225A fuses)

It seems that the Battery selector switch with 3 or 4 functions
does the same function as a battery isolator kit, Is this true? Do I need just one or the other? or are both still helpful for all functions?

This is a 9 year old thread. You should really start a new thread if you want pertinent information.
Anyways...welcome to the circus 😊
