I didn't actually cry LOL. I can't remember what generator you have? I don't think our family can go without full hooks. Since living in comfort on vacation is nice. It's much easier to keep wife and kids cool then hot and hear them.

We have the Tri-fuel version of the Yamaha 3000SEB with Remote Start.


A bit heavy but it does the job. It will handle our 15K AC in Key West and still power the microwave at the same time. In Econo mode, just loafs along and 5 gallons will last a couple of days.

Been watching how the power center does its recharge of the battery bank. At 50% capacity (12.2 battery volts) the power center puts out 13.5 amps when you run the generator. This does not change even if you ramp up the generator. As the voltage rises above about 12.6 the amps drop off to about 8 amps (again the generators RPM makes no difference.)

AT 13 volts (about 85% capacity) the power center drops output again to 2.3 amps of charge.

Using a mixture of charging sources from our dry camp at Patrick AFB we started recharging at 70% capacity. I ran the generator for about 5 hours and brought the battery up to 85%; then I hooked up and drove about 4 hours to a campground in Miami charging all the way. The battery capacity at the campground was 94%. We hooked up to campground 30Amp power and charged for another 8 hours before the TM-2025 meter showed 100% "fully charged".

So my next test will be using a dedicated battery charger instead of the power center and see if the amps stay high and the recharge time is less. Anyone out there use a battery charger instead of the power center to charge their batteries?

FYI
Also of note the campground AC was 112 volts. I hooked up my Franks Autotransformer (brand new Christmas Present from DW) and zoinks! the AC jumped to 120 solid even with the AC and microwave running. Without the Franks unit in the circuit, whenever my compressor kicked in the AC volts dropped to 106. With the Franks autotransformer the voltage cut in and it went right up to 120.

Hello everyone! I just joined the forum, but am not new to RVing. We have had our Rockwood 8281SS since May of 2006. It replaced our previous hybrid (expandable) travel trailer.

Much of our camping is boondocking, so I am familiar with electric usage/recharging concerns. I have been using a Black & Decker Smart Charger for several years with good results. It is a 3-stage charger and will automatically shut off when the batteries are fully charged, so I do not need to worry about ruining my batteries as I would if charging straight from the generator. The initial charge rate is 40 amps if selected. You can choose from 40-20-10-4 amp initial charge rates. It will charge much faster than the power center in the trailer. I hope this helps the discussion.

I would love to get this lou, but I can't to afford to loose a arm to pay for it.

You Rock! That exactly what I was looking for. Without the TM2025 I would have never known.

Glad to help. I use two Trojan SCS225s wired in parallel:

Trojan Battery Company

Obviously depending on electrical usage, I can get 3 to 5 days and still be above 50%

I use two Honda EU2000i generators with a parallel kit (I got them before they had the companion model option). I only need both if I am running the A/C (not often). Every few days I run the generator for a few hours with the Black & Decker Smart Charger to get everything back up to 100%.

I found these batteries.

I have been following this thread, trying to figure out what is best for my situation. I understand that the generator takes forever to charge the batteries. Even after running the generator for a couple hours, my battery is still not up to full capacity. I think 1 of the reason that I start with a low battery is that I have to open the slide (pulling a lot of amps) at the 1st of a dry camping trip, and the battery never completely recovers from that.

In reading this thread, it seems like it would be best to use the battery charger on my generator, or use a portable battery charger. So, so I have some questions concerning those options.

1. Should the battery be disconnected from the camper ?? I am thinking yes, and the generator battery charger or a portable charger may put more current to the appliances that what they can handle.

2. Which is best, the generator battery outlet or a portable charger?? Often times, I am parked at the rear of my camper, and the generator and battery are 30+ feet apart. I could run a 120 volt extension cord to a portable battery charger and do it that way. Or rig up a 12 volt extension cord to use the built-in battery charger on my generator.

3. I would have to presume that plugging the generator into the camper and charging the battery via 12 volts would be a big no-no ?? But that should be OK if I take the battery off-line ??

I am not an electrician and I don't fully understand how everything works. My understanding is from the information (often conflicting) I obtain from research and my personal experiences, so take it for what it is worth.

Because we often boondock, I wanted longer battery life and went with a dual 12-volt battery set up using the batteries I previously posted. Although the batteries lasted longer, they also took much longer to re-charge. I literally could plug the trailer into the generator and run it all day long and still not have them completely recharged using the power center in the trailer. The reason was because of the slow charge rate of the trailer's power center as explained by herk7769.

I therefore began to charge straight from the generator (Honda EU2000i). I did not remove the batteries from the trailer, I have installed a battery disconnect, so I would isolate them from the trailer while charging because I did not know if there would be a problem charging while using the batteries. It was a little inconveneint not having electricity in the trailer while charging, mostly by not having the water pump available for water for toilet usage and I had to watch the batteries carefully so as to not overcharge them. This obviously kept my attention and there are plenty of other things I would rather be doing than watching batteries while camping. The result is I usually would not completely recharge the batteries, but just add some juice to them.

I then learned about the Black & Decker Smart Charger which has worked well for me as it will charge much faster than the power center in the trailer and I do not have to monitor it. I hook the charger to the batteries and plug the charger into the generator. I usually have the generators away from the trailer a distance so it will be quieter and use an extension chord from the charger to the generator. At first I disconnected the batteries while charging like I did when charging from the generator because I did not know if I could charge while using the batteries.

Finally a friend convinced me that I did not need to disconnect the batteries while charging. So for three years now I have continued to use the trailer as normal while charging and have not had any problems. It has worked well for me.

I have NOT had the trailer plugged into the 30-amp service of the generators while charging. I do not know if that would cause problems or not and I don't want to risk problems unless I am sure it can be done safely. And there is no real need as the only benefit would be the use of the A/C ( in which case I would be running the generator anyway), microwave and television.

Hope this helps. I have not had any problems running the battery charger while the batteries are in the trailer and in use.

Gotta love Florida this time of year, especially with the cold and snow in the NE
