If average persons hadn't put out substantial monies for this stuff, I'd say this comedy of errors would be hilarious. But it isn't. The emperor has no clothes and it's not pretty.

Davydd: I'm not up to snuff on these battery systems. What happens to them during prolonged storage, in cold climates? Eventually everything will run down, no?

I don't like it either, since it's patently untrue. It's a shame they need to stoop to lies. I used to have a lot of respect for Yan.

ARV gives us a way to safely isolate the batteries for storage. You ensure they are fully charged, then follow the storage procedures. There are different procedures for storage with and without electrical hookup to ensure the batteries are protected.

I've got the two new Group 31 AGMs ready to pick up. We've figured out how to install them and RT is providing a schematic for the tech. All set for Thursday morning. We're leaving everything so that the next purchaser would have to option to get the ECOTrek lithiums in the future when all is de-bugged and allowed for retrofits.
Will I dare to leave on Friday to start the trek to AZ?
And perfect timing... I got my RT road service cards in the mail today.

So Roadtrek is saying all the proprietary electronics designed to maintain lithiums is perfectly OK to use for AGMs. Hmm.

Are they changing out your battery charger too?

In cold climates you can consume lithium battery energy but you cannot charge them until their cell temperatures are above freezing. So in prolonged storage it might be best to simply disconnect the batteries when they are fully charged. Unused lithium should last up to 6 months. Or you could apply an external heat source. When we first got home last winter with our ARV with three days before taking off again it got down to -5F. As insurance and a bit of curiosity because I knew I might head out again next February I wanted to see if an external heat source could warm the batteries. I slid one of those 1500w portable oil radiators on its side under the battery bank and warmed the batteries up to 60 degrees overnight. So now I know I can head out in the winter at any time. It seems when the batteries are in use they stay warm. I am drawing 6-14 amps almost all the time. If you just leave it plugged into shore power the heating pads would come on. I'm not sure what I will do this winter. I'll probably experiment a bit.

Not really... the added BMS taking up so much space in my limited cabinets will no longer work. but we are leaving in.
Other than that, the inverter and solar monitor are the same as with the AGMs. There will be some wiring changes which is why they are sending the tech the schematic, I would assume.
As I understand the charger is "in" the inverter? Same inverter for AGMs or lithiums.
Please excuse any huge errors as I barely understood the old converter/AGM systems...

easiest way to remeber- roadtrek uses combination inverter/converter/charger.
for some reason manufacturers only call them inverter/chargers

Make sure they have reprogrammed for the correct voltages and charging phased for AGM. Just dropping the batteries in is not enough.

Maybe they call them inverter / chargers because that's what they are.
Converters can supply their rated amperage at a voltage suitable for long term use in an RV. The converter in my van for example can supply up to 45 amps at 13.6v filtered DC with or without a battery installed as long as it is plugged into grid power.
Would the 12v side of your Roadtrek function if you removed your battery (if the battery failed for example)? If so it functions like a converter. If not then it is just an inverter charger.

I just have to quote the late Yogi Berra here: "It's déjà vu all over again."
--------------------------------------------------------------------------
It took a while for a lot of information about E-treks to become public knowledge and it could be the same with information about the Ecotrek battery system.
Fingers crossed for Roadtrek & their customers that it's all sorted out quickly and that the system proves to be reliable for the longterm.
On the warranty / E-trek front these folks - The Etrek Blog | The adventures of new RVers - are getting their Roadtrek back from being repaired at the factory.

I also noted the jumper cables on that e-Trek at the Hersey show. Also noticed how noisy the inverter/charger was while running. Not something I'd want while sleeping in the bed above it.

They were charging one of those portable power packs from it. For what purpose, I don't know. Maybe so they could later jump start some of the vans.

aimspower LF inverter chargers are-gasp- rebadged zl powerstar inverter /chargers
their manuals for these models are much better than from zl power itself.
roadtrek has opted to buy direct. zl power LF used all over the world in many installations-far mor than the brands wincrasher sites

Probably 'cuz all the lithium batteries were dead.

That's kind of my point Gerry. They're budget priced units.
You see it in both the pricing and the specs:
Outback inverter / charger:
Output Voltage Regulation +/- 2% for Outback
Total Harmonic Distortion 2% for Outback
Outback Power Inc. - Mobile Inverter/Chargers Sealed FX2012MT
From the Aims manual you posted:
Output Voltage Regulation 10%
Total Harmonic Distortion 7% to 10%
I just think using top shelf component brands would be good for the Roadtrek brand. Maybe they could offer the top tier components as extra cost options. Just my opinion

why don't you tell them Mark. i have had no problem with my inverter/charger. powerstars are used all over the world.
the ecotrek issues-as far as i know-have nothing to do with the inverter/chargers
actually it appears more likely poor documentation-namely none-explaining how the systems work is the problem.
the ecotrek system has control panels and switches that none of the current ecotrek owners know how to work and the dealers don't know how to work-and no manual on this from roadtrek yet.
an example- the push button switch turning each lithium battery on/off. is it supposed to be on when van closed up or not. does solar panel charging work if the battery shut on or off. does being on or off work with charger.
etc. the answer is NOBODY KNOWS. thats why they are having issues. owners don;t know what they are supposed to do and when-sheesh
