Hi all,
First off, I've never had any trouble running a single 27f flooded battery hooked up per factory. Life was simple. No accessories, no need for power.
All of that is changing now with my kids getting into the sweet spot for camping/hunting/exploring. With my kids in tow, I want more make life better/easier stuff, which requires power. With that in mind, below is an early draft of a system I am trying to get my head around. I think I'm 80% there, but maybe not. I'd appreciate any comments/suggestions.
A few comments/questions:
1) I don't really care about Redarc products, its just the reference material I used. If other stuff works, that's fine too.
2) I like the idea of having two basic/cheap flooded batteries up front in the engine bay. Partly for redundancy/get-home factor due to kids, but also partly because I've heard the fixed alternator on the 80 doesnt play well with AGM. On the upside, by keeping the chemistry the same I basically have an super robust starting battery for like ~$300 in battery cost plus the one-time isolator cost.
3) On the battery isolator, is there any reason the override switch has to be momentary? Could it just be a normal toggle switch so I could link the batteries for starting/winching without having to hold the button? I'm assuming there is a practical or safety issue involved, I just don't know what it is.
4) I don't think I can hook an unregulated/uncontrolled solar panel up to one of the 27F starting batteries without risk of damaging it, but would like confirmation. Ideally the solar would go to starting batteries, then to lithium battery, but I'm guessing I'll need a controller for the solar to do it that way.
5) I'm mixed on hard wiring/mounting the compressor in the rear quarter panel or just keeping it in the drawer and hooking it straight up to the starting battery when needed. I've read it should be fine to run the compressor off the lithium battery, but not sure.
My rough system outline for your critique. Thanks!
