Topic: Battery low after camping
Posted By: MWFlyboy
Subject: Battery low after camping
Date Posted: 18 Aug 2018 at 7:54pm
My wife and I purchased a 180 last year. We’ve noticed an issue with our battery charging and I’m not sure why this is occurring.

When the trailer is parked at our storage facility we have it plugged into a standard 110V volt household outlet to keep the battery charged. Whenever we start a trip the battery indicator shows “Good.” We tow to our campsite running the fridge off battery, then connect to 30 AMP shore power. We are usually connected to shore power for two to three days. When we break down camp and disconnect the shore power the battery indicator always shows “Low.”

My question is, why would the battery successfully charge at the storage facility over a few days, but not charge while hooked up to 30 AMP shore power at a campsite?

Any input would be very much appreciated!

Thanks,

Matt

Seems odd. Do you always camp at the same site? It acts like the 30A shore power connection is not working. Also, don't run the fridge on battery. It will kill the battery. Run the fridge on propane even while you're driving. Most people do.

It would be good to get a circuit analyzer. The power pole might not be wired correctly. I had that happen. I have the http://www.amazon.com/Camco-Integrated-Protection-Indication-55312/dp/B00WED0XBC - Camco Heavy Duty Dogbone RV Circuit Analyzer . It caught the defective pole so I was able to move to a different site.

Thanks for the tip on the refridgerator!

Always different campsites, so that variable can most likely be removed. We run the A/C, microwave and use our outlets, so from that standpoint the 30 AMP shore power should be functioning.

I run my fridge on battery when traveling, my TV has no issues charging same. I think you need to look at the convertor and make sure all the phases are working correctly, with a low battery your convertor fan should be running and the convertor in normal or bulk mode. Check with a voltmeter and don't rely on monitor gauge.

I also run the fridge on battery to travel. I also know that my T.V. outputs a charge to the battery. I know many people run propane as they drive, without a problem. I also know many people climb onto their roof without a safety line and don't fall off. Doesn't make it safe. Driving along with an open flame, especially into a gas station is just plain NOT a recommended thing to do. If you asked 100 people, "hey, do you think it's a good idea to pull into a gas station with a small fire burning in the back of my truck" I feel more than 51 percent would say no, along with calling you a dope. You have a real problem with your battery charge, don't mask it by doing something less safe, it needs to be fixed.

Have you topped off the batteries with distilled water?  The batteries are hard to see in the rPod box.  I check mine 3 or 4 times a year and am always amazed at how much water each cell takes even tho I can see the surface reflection .  Be sure to use a flashlite and a turkey baster or big syringe to add water.

Thanks for the additional advice! Point taken. I’ll investigate the converter.

I have screens in the refrigerator, furnace, and water heater vents to keep wasps out. Screens act as a flame arrestor, so when I am going down the road, I do not have an open flame.

+2 to SH, have always run fridge on propane while traveling.  My dad did the same with a fridge he added to a popup he had in the early 1960's as well as with the built-in on his 1968 Shasta travel trailer.  No issues with propane, nor have I ever read of or known of anyone who has ever had a safety issue while running their fridge on propane while traveling.

I'm not saying anything pro or con, but the FR newsletter this week published pics and stories on RV fires at gas stations, first I had ever seen, won't comment on every cause but they attributed to propane and gas issues. I am sure there are numerous reasons. As long as my TV and charging system can handle a reefer and traveling, I'm sticking with the 12V, I think if your charging system is not up to par, the propane option is best. Sure I'll get dislikes, but end of the day I have no fires whatever the reason.

+1 to Mike. Charging with propane is always safe; until it isn't. Problem is, you may not get a do over if something goes wrong.

When I was a kid, a friend and I were involved in a propane incident and open flame. The other guy died several days later when the blisters in his lungs burst and he drowned in the hospital, since then I have a respect for propane and open flames. Everything is right until it goes wrong.

Problem is running the fridge on battery while towing. It draws about 12A to run off of battery. Most vehicles will not provide that much to a trailer via the 7 pin connector. Whatever it does push, the difference is drawn from the battery. 

Towing with the fridge on LP is risky because you usually have to put gas in your vehicle, and running the fridge on LP means "fire". Fire close to a gas pump is not a good idea. I'm not sure anyone's ever been blown up by doing this, but it isn't something we should risk. 

Get your fridge cold in advance. Pack it with NON PERISHABLE things like water bottles or such. Put some frozen water bottles in when it's cold. It should stay cold enough for a good amount of time.

This has been a topic forever, I ensured my TV will charge TV battery and supply needed draw to TT. SO for now, my choice is to run fridge on battery when traveling. I do still carry a large cooler which has ice and perishables. I have never had a low battery when arriving at campsite. BTW I run the fridge before departing to get it cold, put frozen reuseable bags in it and I lower temp setting when traveling.

+ 1 to SH

An open flame would be a candle burning on the outside of the pod.

Inside the pod would not be an open flame until the door is opened.

Last, just for kicks. Proven fact that almost all gas station fires are a result of static, not open flame.

I am well aware of the hazards of propane. In my younger days, I was a volunteer fireman. We did propane safety training which included getting up close and personal with propane fires such as a flaming "Christmas tree" being fed liquid propane by a tanker. We had three people, two with hoses and one in the middle whose job it was to reach the valve at the base of the "tree" and simulate turning it off, after which we had to back away from the fire without getting burned. It was pretty intense! We also had some house fires that involved making sure the bulk tanks up next to the house did not get too hot and to move them away so they would not explode. Boiling Liquid, Expanding Vapor Explosions (BLEVE) are very, very bad.
Knowing all this, I would not risk using propane with the refrigerator if I thought it had a high probability of causing a fire. I would not be able to dry camp if I did not use propane for worry that something might go wrong. As it is, I sleep quite well with the refrigerator on propane and don't worry about using it on the highway, knowing that I do not have an open flame.

I can understand the people that don't have a choice of using battery, or propane, choosing to travel with propane. I've done it once or twice when i forgot to switch over before getting on the road. But IF you have a choice, and you don't use battery, I would call that a poor choice. Most safety rules don't come about because something bad happens every time you do something. They come about because of the one in a million times something bad happens. Osha demands that safety glasses be worn to do some of the most ridiculous tasks. I worked in machine shops with flying chips everyday and never used to wear them. Did I get hurt? Nope. Was it a very good choice? Nope. I now know better, and I never enter a shop without them. I see people who advocate not using a sway bar all the time. What possible reason can anyone say you should "NOT" use a sway bar of some type.

Question one: When at the campground have you switched the frig over to shore power?
When I Boon-dock, frig goes over to propane. Frig draws far too much DC power to run on battery.

Question two: Is your TV setup with a large enough alternator to run the Frig and charge the battery?
Many are not..

And lastly (for now): What else are you running that is drawing power?
Everything has to be considered here. Running the AC, Micro, Blender, Electric Heater, etc, etc...
How much power are you drawing and what is left to charge the battery ('s)..

To the balance of this thread: I run my frig on battery while traveling. Why? It works and my batteries get a charge as well. At 17mpg average towing (46 days), I'm happy with my setup.

Rubert & Lily have been very good to me!

T2,

I have not seen it on line. I think it is something I clicked on to receive when I signed up on the FR Forum. I get it once a week in email, a summation of posts on their forum, covers all RVs not just Pods. Pretty interesting as far as info.

This is an interesting topic.  By all means, to each is own.  I've looked pretty hard though and more or less, at least, invited other people to point to a rule about not using propane fridges while traveling or at gas stations.  An official rule, issued by a state or federal agency or a law.  I haven't found it and no one has pointed me to it. 

My opinion: there's risk to getting out of bed in the morning.  It's all about risk assessment, which, barring clear statistical data, is pretty much a matter of personal judgement.  Sure, there are stories about fires and deaths but there is also documented evidence of meteors striking the earth and destroying thousands of square miles and even wiping out a lot of the life on the planet.  I still go outside and I run the fridge on propane while traveling.  That's just me though.

At this point I'm not sure I'd change my mind about the fridge even if someone uncovers a law somewhere...

It's been pointed out before but there are almost no three way fridges over 5 cu.ft. in size. Hence most larger trailers and all class C and class A rigs do not even have a battery option while traveling. They run an propane and I can guarantee they are not turned off at gas stations.

Thanks for all the replies concerning our issue and for the spirited debate about propane use while in motion.

As is often the case, Occam's razor has proven that the simplest solution fixes the problem. It turns out that the battery cables were not tightened down enough at the battery. This resulted in actual battery voltage being about a volt higher than what was being registered by the trailer.

On our trip this past weekend everything performed as it should! We returned home with a full battery. Again, thanks for all the input!

Cheers,

Matt
