I've read every thread I can find on 2nd battery installs and have learned a lot, but I'm still left with a couple questions as most do not seem to include a winch setup.
My winch (Smittybilt X20) specs are:
Line Pull: 3k 6k 9k 12k
Amps: 138 218 260 330
Based on my understanding this should require 2/0 or 3/0 cable but I don't see anyone doing that. Is that because the draw from a winch isn't long enough to overheat the wires?
What about voltage drop?
Eventually I'll be wiring up other stuff on the house battery (fridge, lights, inverter, etc) but that all seems negligent compared to the winch. The other thought I had was would it be better to just isolate the winch to the starter battery and keep the winch off of the dual circuit and use a lower gauge wire/fuses for all the house applications.
Any links too good resources would certainly be appreciated.
