~Optima's aren't supposed to last that long tho'~
There's more then one way to skin a cat...
Same goes for dual battery installs and winch hook up.
My system works to isolate the starter battery and e system
from the heavy loads associated with winching.
An internal short or short at the winch's leads...
could spell disaster for other winch install methods.
but some precautions can be taken for that as well.
My Aux. battery carries all the heavy loads...
So if failure occurs...
The starter battery/e system will be unaffected
and I will be driving home that day.
(possibly with a fubar'd Aux. battery and winch, but oh well)
If the winch is hooked up directly to the starter battery...
I might suggest that a breaker be run on the +POS side of the winch.
To better protect your electrical system.
If not... make sure you bring along some fuses/relays with ya.
Hopefully a fuse/relay blows before too much heat occurs and melts shit.
The the method you may follow may be more popular/efficient...
tho' it still doesn't mean it's what's right for everyone.
If the winch is farther from the alternator...
Using larger (awg) cable should be able to compensate.
Resistance might be slightly higher...
but is likely not a deal breaker.
I use my winch for self recovery and assist...
it's not really meant for industrial use.
It's most important to me (security)
to have the starter battery and e system separated
From the winching duties.
Alternator voltage remains the same/constant to either my Stater or Aux. battery.
The Isolator will send the power to which ever battery
is demanding power the most, first.
I do not use a battery combiner... never needed that.
My winch load is only drawn off the Aux. battery/Alt.
It's a deep cycle 34/78 YT...
and I have never irreversibly drained it during use.
The alternator has kept both batteries charged and ready.
Even during a heavy pull...
the Start/Aux. battery are able to effectively maintain/regain any lost charge/capacity.
But then... I don't run my winch continuously like some nimwits would.
Instead... I pull in timed increments while letting things cool down in between.
I have a HO alt. I have yet to install...
Haven't really needed that as of yet...
But will be installed to insure that supply meets demand.
I never said you were wrong...
nor that... others advice was wrong.
Just said I was ignoring your comments
Not every dual battery set up
has the same intended purpose or goal in mind.
A winch can be run to either start/aux battery...
and made to be equally effective and efficient.
The batteries can even be combined...
if you think you need that. ( I never have)
If my system were fubar...
I think I'd be the first to know.
Having security is more important then have anal-retentive efficiency
I'm not really offering any advice here...
just defending my own choices.
to each their own of course...
follow whatever advise you think is best for your needs/use.
