Single vs Dual battery switch

[afred1988]

Hi all,

I was wondering everyone’s take on the single vs dual battery switch? I have never had a cobalt without a dual switch but my new R5 is coming with a single. Does anyone think it’s worth throwing the dual in there? I’m out on Lake Winnipesaukee so not to far from shore in any direction.

Is it a single switch that controls two batteries? There are two types, a 1/2/both switch and the other, which the newer boat come with, which is on/off and combine. The latter is basically two single pole switches to turn on and off two batteries. One battery goes to the engine and the other goes to the house. It also has a 3rd position to combine the two in case your starting battery is dead. It is the best way to go if the boat is wired for it.

That's a good explanation. I've never really looked at it or thought about it as ours was new in 2019 and batteries in boats have usually lasted me at least 4 years.
