MrSkippyJ Posted September 24, 2017 Report Share Posted September 24, 2017 Why do you want an isolator?

SnowDrifter Posted September 24, 2017 Report Share Posted September 24, 2017 Where you install the isolator depends entirely on what you intend to use it for. Could you give me some more info? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
boom50cal Posted September 24, 2017 Report Share Posted September 24, 2017 Why waste the time with an isolator? I'm nearly certain the factory batteries are AGM, just tie in with them. Ford's reasoning with stock AGM's being that in the event of a crash or a rollover, less chance of battery acid leaking out and causing environmental harm.

MTHOMPSON Posted September 25, 2017 Author Report Share Posted September 25, 2017 I was under the impression (no knowledge of batteries/electrical...so let this be known lol), that since the 2 stock OEM batteries are different amps than than the XS battery I am adding into the picture, an isolator would be needed so not to draw lessen the life of the OEM batteries due to audio system. I assume in best practice, all batteries should be the same...but since this is not the case or will not be anytime soon (just had both batteries replaced under coverage about 4 months ago) an isolator is needed. Going to add inline fuse in and out of the XS battery. Link to comment Share on other sites More sharing options...
jumpshowhigh Posted September 26, 2017 Report Share Posted September 26, 2017 When it comes to isolators....highly recommend the Perfect Switch Dual Rectifier at http://www.perfectswitch.com/isolators/dual-rectifier-150-to-300-amps/ They even have larger units for higher output alternators all the way up to 600 amps. I put this in my Land Cruiser several years ago and it works exactly as advertised. Link to comment Share on other sites More sharing options...

As these 2 other members (high post counts) seem to advise that its not needed for my specific setup. Link to comment Share on other sites More sharing options...
SnowDrifter Posted September 27, 2017 Report Share Posted September 27, 2017 Only time you'd want an isolator is if you're either doing something like a car show where you're playing car off but don't want to run your starter battery down. Or if you have a mixed battery set up like a custom lithium bank and a lead/acid battery. Outside of that, an isolator is another cost, failure point, and a potential for resistance in the circuit ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
WalledSonic Posted September 27, 2017 Report Share Posted September 27, 2017 Even then, mixing AGMs and lithium doesnt require an isolator. People usually do it as a safegaurd that under complete catastrophic failure that they'd be able to drive home. EDIT: and even then, only if it was connected appropriately.

MrSkippyJ Posted September 27, 2017 Report Share Posted September 27, 2017 I see no reason to use one in your case.
