Battery cut-off

[G&N Farms]

I've had the battery go dead a few times overnight. After reading a lot of post, it might be the cutout on the generator. Maybe, maybe not. Anyway, I am going to put a battery disconnect of some kind.

Should I put it in-between starter and battery at the starter or is there somewhere else that would work better? I don't know if I want a big-ol switch hanging off the starter. Just asking.

Thanks.
