The only battery disconnect switch that I know of is the BlueSea one. It will connect the alternator field after the batteries connect and disconnect the field a before the batteries connect.

That would pretty much depend on how the Balmar is hooked up, I think.

If the "on (ignition)" wire for the Balmar is coming off the coach batteries, the Balmar will not activate and there should...

Interesting that you can run the relay off the little indicator output, good information.

What we need is for Blue Sea to come out with a bistable relay like the yours and ours, but that does the...

I do think that the Balmar stuff could be damaged from a BMS shut down with the engine running, for whatever reason, if there were no AGM. Even shutting of the manual switches on the modules might...

You certainly could monitor the coach batteries with power to the Voltstart, as long as the Voltstart has a separate "sense" wire to determine SOC.

Unfortunately having it that way would allow the...

I would certainly hope that the Voltstart won't start the engine unless there is a battery connected to the alternator, so the alternator doesn't go way high and destroy stuff. Even Roadtrek...

Because they did it right it in the first place and didn't need to put a big AGM bandaid on them. :hide:

The battery needs to be in the system, and stay in the system in nearly every alternator system, as the regulator needs to see the battery for voltage reference and load to drain spikes. Same with...

I think Roadtrek may have fed you a line on the AGM and charging sources. I don't know the brands or specs on their shore chargers or solar controllers, but essentially every one I have looked at...

It certainly seems like it makes a lot more sense to shut off the charging sources, than disconnecing the batteries when full. A few simple relays to control alternator field, solar panels and 110v...

Wouldn't that mean that the charging would keep going on and off when you were on shore power because the inverter would run off the output side wouldn't it?

That would be the often mentioned death spiral, where the alternator does not have enough hot/idle capacity to run the AC and recharge the batteries at the same time, so the batteries lose SOC on...

I really don't understand a bunch of this about the charge and discharge sides of the batteries. Sure would be nice to have a wiring diagram, but of course that won't happen with a Roadtrek system....

Yep, the two batteries in front of the passenger side rear wheel are in the stock location for two battery systems.

This post should help with pic posting. Just remember no Photobucket allowed.

The two extra batteries would go in compartments behind the rear wheels last I heard, and wouldn't cost you space.

The spare would go inside the van without the tire carrier, which is not very...

I would agree that many just want it to work, just like your car, turn the key and go. No problem there.

But....would you ever buy a car without a gas gauge and no warning until the car wouldn't...

I just took a look at the battery power management instructions on the Roadtrek website, and they still list the parasitic loss as 60 watt per module. If it were really lower than that, I would...

I certainly would not go as far as saying the idling is stupid, but I would hope for everyone's sake that it is mostly unnecessary. A big lithium system of 800 or more AH should give nearly everyone...

I think a "rough", but more applicable to the real world, answer to the parasitic loss is for those with lithium batteries to just turn on a module with no load on it and see how long it runs before...

Yep the parasitic in the Roadtreks really is that high. 60 watts, 5 amps, 120ah per day wasted. It is not a function of lithium batteries in general, just the poor design of Roadtrek's system.

Here is the post that said the losses were still high. 60 watts continuous, 24/7.
