dual batteries, management and winch

**kitacooch** · 21st September 2008, 08:22 PM

Hi there, am looking to purchase the SC80 from trackside, but noticed 2 wiring options, 1 battery winch operation and 2 battery winch operation.
Anyone have an opinion on which is best option and put it in Lalum terms for me.
I guess the 2 battery option means you powering winch from both batteries is better for battery life and loger winching time, but how does this effect the fact running cranking battery and deep cycle axillary, or are you supposed to run deep sycle as a cranking aswell. Also what is the marine battery swith for, why would you isolate the batteries from each other.

1 battery option i thought would still pull power from both batteries until cranking battery gets to setrain level. As you can see am little confused and seem to be reading the wiring diagrams wrong.
Help please.

I'd suggest you get advice from "the horses mouth" so to speak.
i.e. pm Drivesafe on this site.

I have the SC40 and my winch is running off the main cranking battery, with this setup, my auxillary battery is a Fullriver AGM deepcycle, i have recently removed the marine switch though.
