What is Dry Camping?
Dry camping, also called boondocking, is camping in your RV without any hookups—no water, sewer, or electricity. You rely entirely on what you bring with you, including your battery bank for power.
This off-grid style of RVing is popular for its freedom and cost savings, but it also means your battery becomes your lifeline.
Whether you’re parking in a national forest or overnighting in a parking lot, having the right battery ensures your lights, fridge, fans, and devices keep running. Dry camping can be incredibly rewarding, but only if your power setup is reliable.
Why Battery Choice Matters
When you’re dry camping, your battery isn’t just a backup—it’s your main power source. That’s why choosing the right one can make or break your experience.
Here’s what a good dry camping battery should handle:
- Power essential appliances like lights, fans, CPAP machines, and fridges
- Charge consistently from solar or generator sources
- Survive temperature swings, especially below freezing
- Last multiple days without needing a full recharge
- Support deep discharges without damaging the battery
Different Battery Types
Not all RV batteries are built the same. Here’s a quick breakdown of the most common types you’ll see when shopping for a dry camping RV battery:
- Lithium (LiFePO4): Lightweight, fast-charging, long lifespan, and ideal for off-grid use. Most expensive, but lowest maintenance.
- AGM (Absorbent Glass Mat): Safer and spill-proof alternative to lead-acid. Mid-range cost, decent performance, but heavier.
- Gel: Stable and maintenance-free, but slower to charge and sensitive to high amperage.
- Flooded Lead-Acid: Cheap but bulky and requires regular maintenance. Not ideal for dry camping unless you’re on a tight budget.
Key Features to Look for in a Dry Camping Battery
Not every RV battery is built for life off-grid. Dry camping means you’re completely dependent on your battery for power, so choosing one with the right features can make a huge difference in comfort, safety, and convenience.
Battery Capacity (Ah or Wh)
Battery capacity tells you how much energy your battery can store and deliver. It’s usually listed in amp-hours (Ah) or watt-hours (Wh). The higher the number, the longer your battery will last between charges.
For casual weekend trips, a 100Ah battery may be enough to power lights, fans, and charge your devices. But if you’re running an inverter, fridge, or other larger appliances—or dry camping for more than a night or two—you’ll likely need a 200Ah or even 300Ah setup. More capacity means more freedom to roam without plugging in.
Depth of Discharge (DoD)
DoD tells you how much of your battery’s stored energy you can safely use. With lithium (LiFePO4) batteries, you can typically discharge 80% to 100% without harming the battery. In contrast, lead-acid batteries should only be discharged to 50%, or you risk shortening their lifespan.
This matters because a 100Ah lithium battery might give you nearly the full 100Ah, while a 100Ah AGM or flooded lead-acid battery will realistically give you only about 50Ah. That means you’ll need more batteries (and more space) to get the same usable power from lead-acid.
Cycle Life
Cycle life is how many full charge/discharge cycles your battery can handle before its capacity starts to degrade. The higher the cycle count, the longer your battery will last overall.
For dry campers who travel often or live off-grid full time, look for a battery with at least 3,000 cycles. Some high-quality lithium batteries claim up to 10,000–15,000 cycles at partial discharge. Over time, this durability can save you hundreds—or even thousands—of dollars in replacements.
Smart Monitoring
Smart monitoring tools, like Bluetooth apps or integrated displays, make it easy to track your battery’s health. You can check voltage, charge level, temperature, and charging status right from your phone or a screen on the battery.
This is especially helpful if your battery is stored in a compartment or hard-to-reach place. It also lets you troubleshoot issues before they become problems, giving you peace of mind while off-grid.
Low-Temperature Charging Protection
Lithium batteries can’t safely charge below freezing. If you try, it can permanently damage the cells. To avoid this, many high-end lithium batteries now come with built-in heaters that automatically warm the cells when temperatures drop near 32°F (0°C).
If you plan on dry camping in the mountains or during the winter, this feature is a must. It ensures your battery will charge reliably—even on cold mornings—without needing external heat pads or workarounds.
Build Quality & Weather Resistance
Dry camping often means rough roads, dust, rain, and unpredictable weather. A well-built battery can handle these conditions without skipping a beat.
Look for models with solid casing and a high IP (Ingress Protection) rating. An IP65 or IP67 rating means the battery is sealed against dust and can withstand splashes or even brief submersion. This kind of protection is especially important if your battery is stored in an exterior compartment or exposed area of your RV.
How Many Batteries Do You Need for Dry Camping?
Most dry campers need at least one 100Ah lithium battery to power basic RV essentials for a night or two. For longer stays or heavier power usage, you’ll likely need 200Ah to 300Ah or more, depending on your setup and appliances.
The exact number depends on what you’re running and how long you’re staying off-grid. Lights and USB chargers don’t use much power, but add in a fridge, inverter, or CPAP machine, and you’ll need more storage. Many full-time RVers use two or more lithium batteries in parallel to meet daily needs and maintain backup capacity.
It’s a good idea to calculate your average daily usage in watt-hours (Wh) and match that to your battery bank. Then add 20–30% extra as a buffer for cloudy days or heavier-than-normal usage.
RV Battery Maintenance Tips for Dry Campers
Keeping your battery in top shape extends its lifespan and ensures it’s always ready when you need it. Here are a few easy tips:
- Store batteries in a cool, dry place when not in use
- Avoid fully discharging your battery regularly (unless it’s lithium rated for it)
- Check connections for corrosion or loose wires every few weeks
- Use a quality charger or solar controller to prevent overcharging
- Keep an eye on temperature, especially in winter—use heaters or insulation if needed
- If your battery has Bluetooth or a display, check it periodically for health indicators
Final Words
Dry camping gives you the freedom to explore off-grid, but your power setup needs to be solid. Choosing the best RV battery for dry camping comes down to knowing how much power you need, where you camp, and how often you go off-grid.
If you’re a weekend warrior or just getting started, the Battle Born 100Ah is a solid, dependable pick with cold-weather support and a long lifespan. For more serious campers or full-timers, the LiTime 12V 300Ah LiFePO4 Battery offers massive capacity and smart features that make boondocking a breeze.
No matter which route you take, investing in the right battery will make your off-grid adventures more comfortable, more reliable, and a lot more fun.
FAQs
Can I use a regular car battery for dry camping?
Not recommended. Car batteries are designed for short bursts of high power (like starting an engine), not for steady, deep discharges. You need a deep-cycle battery designed for RV use.
What’s better for boondocking: AGM or lithium?
Lithium is better overall—lighter, longer-lasting, and more efficient. AGM can work if you’re on a budget, but it offers less usable capacity and a shorter lifespan.
How long does a 100Ah battery last when camping?
It depends on what you power. A 100Ah lithium battery can run basic lights, fans, and phone charging for about 1–2 days. Running a fridge or inverter will shorten that to less than a day.
Is solar necessary for dry camping?
Not strictly necessary, but highly recommended. Solar lets you recharge your batteries during the day, reducing the need for generators or external hookups.
How to charge RV batteries off-grid?
You can use solar panels, a generator with a battery charger, or your vehicle’s alternator while driving. Just make sure your system is compatible with your battery type.
