6v Deep Cycle batteries are made for golf carts. One common change that RVers make is to change from 12v batteries to 6v batteries. Multiple batteries can be wired together in “parallel” to supply more amp hours depending on the power demands of the coach, and they will last for an extended period of time. Since you can only discharge 50% of the battery to keep it safely working, you should get 10 hours of power before recharging. A little math will translate that need into required amp hours.ĭeep cycle batteries are designated by “Amp Hours (AH).” The amp hour rating is the total amount of power you will get pulling a consistent number of amps.įor example, if you have a battery rated at 100AH, and your rig is pulling 5 amps consistently, you can expect to get 20 hours out of the battery. In choosing a proper battery system for your rig, you need to know how much power you will consume in the course of a normal day. This type of battery is called a “deep cycle battery” due to the deep discharge. If you are boondocking, the charge/ discharge cycle can happen daily. They are discharged deeply (down to about 50%) and then charged up again. These batteries are designed to provide power in lower amounts, over a longer period of time. The 12 volt power system needs a different type of battery to run efficiently. This is fine if you are only running on batteries for very short periods of time, like a few hour. Unfortunately, because they are the least expensive type- RV manufacturers will also tyically install them into the 12volt power system for the RV. They are designed to store power and discharge it in a short burst (when starting the engine.) These batteries are also designed to NOT discharge very far or very often. The “chassis” type of batery is the type you will typically find used as a car battery or under the hood of a drivable RV. These systems work very differently and require different batteries. The first is the battery that starts your engine, and the second is the type that runs your 12 volt electrical system when you are not on shore power. However, there are 2 different uses of lead acid batteries in an RV that you should be aware of. They are comparatively inexpensive to other types, and are pretty reliable with proper care. RV manufacturers typically use a lead-acid type of battery. Types of RV Batteries Lead Acid Batteries If you want to make a regular practice of boondocking, a battery upgrade is probably in order. While these batteries are fine for short overnight road trips or weekend camping trips, they typically are not capable for longer stays. Most RVs come supplied with at least one battery from the manufacturer. The power can be supplied using either solar power or a generator, and the storage is supplied by using batteries. Therefore, the camper must have the ability to both generate AND store electricity for their use. All necessary services must be provided by the camper. “ Boondocking on Battery Powerĭry Camping (or “boondocking”) is the practice of rv camping without any hookups. The better they are charged, the longer they will live. “3 stage chargers are designed to vary the current and voltage to best charge the batteries and keep them at their most efficient. This time can be extended by adjusting power usage, conserving water (not running the pump), shutting off lights as much as possible, or simply by upgrading or adding extra batteries. Under normal use conditions – lights, propane refrigerator, charging phones etc and water pump, a 12v battery will last 2-3 days. When the RV is not plugged in, that electricity usually has to come from batteries. The first concern of anyone considering dry camping in the wilds is “How long will my battery last boondocking?” In order to enjoy lights, refrigerated food, running water, A/C, or heat will require electricity in some form.
