I think that Roadtrek looks at the AGM battery as a "disposable" necessity to making the lithium system function (which it does only sometimes, though). Tesla does a similar thing with their cars. ...

Has Victron moved to full shut off chargers for lithium now, with the settable stop point? I assume they might be because of the voltage trigger point relay they have in the monitor, and voltage...

I just took a look a the monitors George listed, as I hadn't looked at a couple of them since they were updated or new.

The Victron does look very nice, for sure, and the others all have decent...

I don't think that they were wrong in their assessment of the quality of the Roadtrek lithium design, as there do seem to be lots of issues and total lack of consistency with some working and some...

Advanced certainly is close, but even davydd got to the point he had to make sure his van stayed over the -4*F where they say you get permanent damage even just sitting, so he couldn't just put it on...

Very hard to tell, and probably would be at least partly determined by how they were charged before the tender went on.

If they are wet cells, you would be able to check the specific gravity of...

Can't speak for the Northstar, but the Lifelines will start to get too hot at about .4C so 40 amps per 100ah of capacity. We have tested this repeatedly and it is very consistent for long charges. ...

I would totally agree with Roadtrek part, for sure, the "perfect" would be a bit of a stretch for me because of the cold weather storage and charging issues which would apply to some of us.

Redroadtrek posted while I was writing this, so some of it doesn't apply now.

The Northstar AGM400 is not a 400 amp hour battery, it is 182 amp hours, so you have 382ah currently and if you are...

I would second that if the 182ah is correct for the Zion, and it would make the idea that the Zion is short on battery capacity more true compared to the mentioned 400ah.

Being AGM, if they are...

If you do have AGM for the OEM battery, it will likely be a TPPL version of AGM, and will have a different charging profile and acceptance profile than the Lifelines, so you could have issues getting...

I must be missing something. The 400ah setup for the Zion is Lithium from all I have heard. The AGM is 182ah, although Roadtrek is inclined to call it a 400 amp battery in advertising.

What...

Very true. If the air conditioning is on, it could draw down a 2 AGM battery system (200ah or so) to 12.0 volts while they were still at a high SOC. Tough call as to where to set things to be safe...
