I agree that they can and are called a lot of things, but in the RV discussions, it is almost always the way I initially described it, from what I have seen. I think the isolator thing was kind of...

I think all you would need to do would be to put in a Trimetric meter and you will now nearly exactly what your state of charge is.

In strickly engineering terms, it could, and probably would, be called an isolation relay. They need to be externally controlled.

In RVspeak, the term isolator is used to describe the diode type...

On the Winnebago drawing, the piece on the left in the component location section looks to be a standard starter type 12v relay, which would be a coil type with no separator functions based on charge...

X2 (at least) Best performance at the best value, I think, is still important to many, but the high end units seem to be dwarfing that discussion a bit. The fact that Winnebago is rapidly gaining...

I think that it would depend on the BMS and how they handle things, because you wouldn't want to have either voltage absorption or float on them when full, per most folks. Of course, the same would...

Yep, only difference is .2v on absorption, which may or may not be against the AGM recommendations. Some actually want you that high. Not a real big deal, in most cases, but you may want to look up...

An interesting thing is that Lifeline mentions similar shortening of life with their AGMs. We will definitely be doing some ventilating to at least try to keep them close to ambient.

I think ours...

I think the information said something like 1/2 the cycle life for every 10* C? above ambient of 25*

Not really missing much. It can be a pain to get around some stuff, though. The tightest spot on our Chevy was in the left front wheelwell area that the cable had to go through, along with about a...

All of that information is also available from the Trimetric monitors, the monitor built into the Blue Sky solar controller, and if you have a charger with shunt controlling it will show it all also...

From what I have been able to learn playing with our system and batteries, which are wet cells right now so I can check the state of charge accurately, about the only way to accurately charge wet and...

Getting back to the damage that can be done by going 80% down on AGM batteries.

Killing them in a year is probably possible pretty easily, although I think that some brands would be much more...

I agree with Marko.

The alternator, in reality, does not create amps, as odd as that sounds. It creates voltage to a (mostly) fixed level.

The rest of the system wiring, batteries, motors, etc create a resistance to...
