Lance 650 Battery Issues?

Hi everyone,

Please forgive my lack of technical terms, I'm a young woman owning a truck camper for the first time and have been figuring out how an RV works for the past year, but I wanted to know if the battery issues I've been having with my Lance 650 are just a part of owning a small truck camper or are an issue. I must mention that I have to use the battery as the places I camp at don't have electricity to plug into.

I bought my 2016 Lance 650 in March. The first trip I ever took it on was a two night/3 day trip and a 3 hour drive each way. My battery lasted for 3 days with no issues or drainage. By the way, a Lance 650 comes with just one deep cycle RV/Marine battery where some of the larger truck campers may have more than one, or a built in generator just like some larger living quarter horse trailers might have 4 deep cycle batteries on them.

After that first trip, my battery barely made it through 24 hours. The only time it has lasted any longer is within the 2x I've gone back to the dealership and all they do is give me a new battery and say the last one was bad. I finally got solar panels installed hoping it would solve my issues, and it has a little bit. I was told to keep the battery on all the time while my camper charged itself everyday. However, there is never enough battery power to lift all four jacks up at the same time, so even with the solar panels I have to use a battery charger at the power level of jumping a car to get all four jacks to work at the same time. My last trip was only a two day, 1 night trip and the battery got really low at abut 5am the following morning. That night I spent a couple hours with a friend in the truck camper and used the rear outside light, and a few of the interior lights, and then woke up to my smoke detector going off at 5am which is my sign that the battery is low. On all my trips the battery is used minimally as I am outdoors most of the day and my fridge is run on propane. I basically just use the interior lights at night.

My question is; is all of this hassle what I should expect out of a smaller truck camper or is their a deeper issue that I am having? I also need to mention that it is rare that I can plug in my 120v connection from my camper to my garage to do a slow, deep cycle charge. My HOA has issues with my camper in my driveway and it is stored on a dirt field.

Any advice is appreciated. Thank you!

  • Hi!

    Looking at the specs for your camper it looks like it is a single battery compartment. That is smallish, but have a look and see if it could hold a single larger battery like a group 27 or 29Did you get the lance option solar panel? It lists as a 95 watt panel. You may want to ask the dealer if a second could be installed.

    Make sure that when you park the panel is in the sun

    Did the camper come with a meter that shows your current state of charge and battery level? (not the little led scale you flip a switch to see. Those are useless)

    Did you run the forced air furnace? These will quickly eat your battery. Pretty much useless for boon docking unless you have a bigger battery and more solar to re-power the battery the next day.

    Never let your battery get below 50% (about 12.5 volts) This will reduce the lifespan and holding capacity of the battery. Get yourself a multi-meter so you can accurately test your battery voltage.

    Driving the truck should be partially charging the battery but you will want your solar and solar charge controller to do the heavy lifting for boondocking.

    Looking at the pics of your camper online, it looks pretty cool. Congrats!
  • Hi horseshoesnhappyhrs and welcome to the TC Forum.

    Well, you are learning fast and the hard way. First, having just one battery is going to just serve you for running the fridge and a few lights for one night. When it is colder than 55*F you are losing about 60% of your capacity in this one battery. Basically, you are asking too much of your battery and each time you are discharging your battery below it's 55% AH capacity (in other words you use it until it is dead and then charge it up) all you are doing is dedicating this battery to a quick and painful (your pocket book) death.

    One of the things you can do now is limit your use of the battery (DC) items, especially if you are using anything supported off a convertor. Also, anything that is going to use heavy amp requirements (Jacks) only perform this with the truck running, as it is providing Amps to your battery through the invertor.

    Also, consider using things like Lap Top and other power hungry items, i.e., TVs, cell phone charging, during day shifts(anything that creates heat is using lots of amps and stealing from your single battery), so as your solar may make up the difference. During cold weather these items will warm to the touch and reveal their Amp thefts.

    There are a lot of knowledgeable people here in this forum so don’t hesitate to ask. Many have experienced the same issues you are now and will in the future, so just ask. Or send me a PM with a specific question, too.

  • One other point and that is your refrigerator on propane is still using battery power to run. Sounds like time for a second battery to make rv life easier.
  • First up, good for you for going it on you own, and good for you for seeking information. Time for home work
    For a basic understanding of deep cycle batteries Battery Faq
    We have a similar form factor in a teardrop trailer. We have a 185W solar panel and 150 amp hour AGM battery. I monitor the battery using a Victron battery monitor which tells me how much current is going into and coming out of the batter. The goal is to keep the battery above 50% state of charge. When you go below this permanent damage to the battery occurs. Which brings up conservation when off the grid we do not use anything that uses resistant heat i.e. a coffeemaker... all lights are LED.
  • The Carbon monoxide detector uses a lot of battery power. We only use ours in cold weather,we just sleep with the roof vent open. If you have 200 watts of solar power you should be fine. Also see if a group 27 battery will fit in the battery box.
