Rich,

Here's the stages that Progressive Dynamics chargers use:
BOOST Mode 14.4 Volts - Rapidly brings the RV battery
up to 90% of full charge.
NORMAL Mode 13.6 Volts - Safely completes the charge.
STORAGE Mode 13.2 Volts - Maintains charge
with minimal gassing or water loss.
EQUALIZATION Mode 14.4 Volts - Every 21 hours
for a period of 15 minutes prevents battery stratification
& sulfation - the leading cause of battery failure.

This thread has some good info on power draw:

Voltage provided by a charging source is only half of the equation. The other half that has not been mentioned is the AMPERAGE that your charging source is capable of sending to your batteries.

Different battery chemistries accept and require different amounts of amperage for full and complete recharging.

Lifeline AGMs can easily handle 1C (1 times the battery bank capacity) or more but they really like a slower, consistent charge of C/5 or 20% of their capacity.

Lithiums can handle a much greater input amperage for charging and never need to be at 100%, as they will not show 'sulfation', or sulfur crystal growth in the plates like lead batteries will if they are not completely recharged to 100% soon after discharge since there is no surfer in a LiPo battery.

ANY standard 'smart' converter will almost never place 100% ( or close to It) of it's charging capacity into your batteries during re-charging. This means that a converter rated at 55 amps will almost never apply all of that amount into your battery bank, requiring extended charging times.

Inverter/ chargers like Magnum have an easily programmable charge rate setting where you CAN apply up to 100% of the charger's rated output to your batteries. It even shows the charge level and charge rate on the ME-RC remote.

Something to think about...........

Thanks Lew.

So - if I had a Magnum, what *would* you set it to for two LifeLine GPL-4CTs?

Depends on the model. I would set the ME-RC for 'AGM1' which is the Lifeline-specific charge profile.

Then if you want to follow the C/5 regimen, you would have 220 amp/hour capacity so C/5 = 44. I would set the charge rate for the MMS-1012 @ 90%. MS-2012.50%, MS-2812 & MSH3012-M.40%.

All of the above charge rate settings will give your chosen battery bank a 45- 50 amp charge at the pre-set voltages recommended by Lifeline and adjusted for temperature compensation IF you have the included temperature sensor properly attached to the battery bank.

Back to the basic question of 1000 vs. 2000 --

Per Michael's [CWCHIEF] recent post on this other thread:

http://www.airforums.com/forums/f448...ne-148661.html

that Yamaha generators can be purchased from US Carburetor, complete with the propane conversion AND with the Yamaha warranty, we are considering the 1000i, per the quote below, mainly to keep our batteries charged in the FC20. I will check our owner's manual, but my recollection is that the battery charger does not draw more that the 1000's rated output of 7.5 amps. Thank you for any thoughts on this capacity issue. The weight savings seem worth it to us.

Peter

PS -- edit -- On p. 8-23 of our manual:

https://www.airstream.com/wp-content...gcloud2014.pdf

the converter is rated at 8 amps. [p. 91/114 of the PDF] Seems like the Yamaha 1000 could handle this, albeit just barely, as the maximum draw of the converter would normally be quite a bit less than 8 amps . . . right? Thanks.

Comparison of the 1000 vs. 2000:

https://www.yamahamotorsports.com/ge...20091d7ca01773

We are considering the 1000 for our FC20 to save on weight (27.9 lbs. vs. 44.1 lbs.). Its only function would be to keep the batteries topped off (7.5 Amps rated AC current).

Thanks again,

Peter

PS -- I will also post this in the following Honda 1000 vs. 2000 thread:

Correction -- "AWCHIEF" for Michael -- apologies.

Since the 12Vdc output of most generators is typically at a constant voltage, it is possible to cook the batteries since the charge is not altered as the voltage in the battery increases. This is why the single rate cheap Airstream installed converter typically has the capability to cook the batteries.

When the user connects their trailer to the 120Vac output of a generator (and hopefully have a multi-stage converter to properly adjust the charge rate to the battery condition) the battery has the chance for a proper charge cycle and which results in longer life..

Solar charge controllers also have to be programmed to the charging characteristics necessary for the trailer's battery type.

Our Yamaha 1000 tri-fuel is supposed to ship in the the next day or two FYI:

FYI on a recent trip, the new tri-fuel Yamaha 1000 gen worked out great for our FC20. It handled both the battery charger/converter and the fridge on electric. We still have the OEM charger, and the batteries were fairly well charged already, but a new Progressive 4655 converter might overload the 1000 gen? TBD

The RPMs went up for the combined load, so guessing this was maxing out the gen, but the breaker did not trip.

The 1000 is really small for storage and very light at 28 pounds.

Yes!

It's normal for the RPMs to increase under load and does not necessarily mean it was maxing out.

Yes I realize that, but the two loads combined have to be approaching 1000 watts, right? [converter/charger plus fridge] The gen has a tachometer but I forgot to check it.

Plus I think the gen output is actually slightly less than 1000 watts.

PS edit see earlier posts re our OEM charger/converter load.

I want to buy four 1000 gen and hook them up parallel, parallel. That way I can custom exactly how many watts I need. I can use one, two, three or four or any combination of these! Have I overthought this?

You are joking right?
