HI,
I have dual Odyssey deep discharge batteries mounted under the hood of my Jeep Wrangler. My battery control system is the one made by Wrangler NW Power products. This system has several modes. Mode 1 has the batteries connected in parallel. Mode 2 separates the batteries so I can use the secondary one for the winch without running into the danger of discharging the main starting battery during a long winch pull. Mode 3 is called the jumper mode which allows the secondary battery to function as a temporary jumper battery for emergency starting. I have used all three modes and the scheme seems to work well.
NW Power Products has all the necessary connectors, fittings, and wiring for any possible hookup.
I replaced my 70 (!) amp OEM alternator with a Mean Green 160A unit. I would have more but this is the best I could do using a V belt system.
I started out with dual Yellow Top batteries but had a lot of trouble with them. About a year ago I switched to dual Odyssey batteries and, so far, no problems.
There is no doubt that dual batteries give a lot of confidence especially with a winch. I have a Warn 8274 which is power hungry. Also, I do a lot of solo wheeling so self-sufficiency is important. So, while dual batteries is an expensive upgrade, I think it is well worth the money.
