12 volt deep cycle does this mean it would not run off my snowmachine battery?
I wouldn't if it were me.
The battery in your sled is a cranking battery not deep cycle and as such is not designed for prolonged heavy draw.
You could try it and as long as your sled has a pull start you should be ok.
You could be reducing the life of your battery using it like that though.
I wouldn't do it with my sled, mainly because it's a 4 stroke with no pull start option.
Not that I could hand start a 1000cc sled any way.
