Dual battery anyone?

[pk9394]

Does it necessary to do dual battery for winch? I looked around the best system is Genesis offroad dual battery kit, with 2 Odyssey batteries, the cost is nearly $1400, thats way too much to use the winch only few time a year!
or should I just replace a better battery like optima yellow top.
anyone had the detail spec on the oem AGM battery in the our car? I only know is group 94R

I don’t think a dual battery setup is necessary for a winch. Unless you are using the winch without the vehicle running (i.e. alternator charging the battery) for an extended period of time, you should be fine. According to the specs, the Warn Zeon 10 winch pulls 409 amps at max load which is significant but not beyond the H6 battery limits.

You don't need dual batteries to run a winch as you'll run the winch with the vehicle running. I have a Warn M8000 winch rear-mounted and wired to one of the OEM upfitter switches:

I do also have the Genesis dual battery setup, but I did this for auxiliary battery to power other devices (not the winch) as well as to have it as a backup battery that can jumpstart the main battery using the Genesis configuration. It's a beautiful setup, and yes, it's pricey as well:
