dual battery kit, ironman

[jabartram]

im considering this Ironman 140 Amp Dual Battery Kit DB001, does anybody have any good or bad reviews?

[WILSON]

Jacque just got one, but has not installed it yet.
I can say we have never had one returned.
Sorry, I don't own one so I can't help with a review.

i have read through that thread before, good info, im an electrical and electronics specialist for the diesel truck and heavy equipment industry, i have worked with many multiple battery systems, i want to isolate my lights and extra electrical equipment from the ignition battery. i have an optima yellow top in my racecar that im gonna transfer over to my fj as the second battery. i just want to be sure i have a proper isolation system.

As long as you stay within the amperage range your fine. Realize though, that if you use a winch on the main battery you won't gain any reserve capacity for the winch with that setup. Or any other high current power draw device for that matter. As soon as the voltage drops down below 12.8 volts you effectively have one battery to work off for a winch.

i want to run a winch from the secondary, i dont want anything on the primary battery except oem.

How do you put on 35 inch tires with no lift? I have 33 inch and had to lift and modify frame for them to work

Me Too - I'd be interested in seeing how you do this...


I am considering the The Dirty Parts Dual Battery Kit
or the Ironman 275 Amp Dual Battery Kit DB002

which one is better?

I want to have an adequet amperage on the solenoid right?
and probabaly need to get a higher amp alternator?

Thanks
