Powering Your Journey: Navigating Battery Choices and Solar Options
As outdoor enthusiasts, we understand that the key to a truly immersive camping experience lies in the ability to disconnect without sacrificing comfort or at least certain necessities. That’s why we’ve carefully curated our power solutions to provide campers with the freedom to explore off-the-grid longer while still enjoying some basic conveniences. In this guide, we’ll explain our recent move away from AGM batteries in favor of lithium, help you navigate the different battery size options, and shed light on the benefits of incorporating solar into your adventure trailer setup.
The Shift to Lithium: Efficiency and Reliability Now Come Standard
Welcoming a new era, Timberleaf Trailers has fully embraced the benefits of lithium batteries over traditional AGM technology by making lithium the standard in every one of our trailers—offering a transformative camping experience to all Timberleaf customers. Lithium batteries provide a slew of significant advantages, from packing more energy into a smaller and lighter design to allowing you to access more power without sacrificing valuable storage space or fuel economy, making your journeys smoother and more enjoyable. With a superior depth of discharge, lithium batteries also provide longer-lasting power, ensuring you can venture further and longer with greater confidence. They also allow campers to enjoy faster charging times, spending less time waiting and more time exploring the outdoors. The lower self-discharge rates also mean your teardrop trailer is always ready for action, providing on-demand power even after extended periods of inactivity.
And most importantly, lithium’s superior energy conversion efficiency minimizes heat loss, which optimizes power usage — the reason they outlast their AGM counterparts. This translates to fewer replacements, reduced maintenance costs, and a sustainable power solution, all while contributing to an eco-friendlier camping experience. The upgrade to lithium batteries not only enhances the overall performance of your trailer but also aligns with our commitment to innovation, ensuring our customers enjoy the utmost convenience and reliability during their adventures.
Choosing the Right Size: Tailoring Power to Your Camping Style
While you no longer have to choose between AGM and Lithium, the choice between battery sizes remains pivotal in tailoring your camping experience to match both your preferences and the demands of your equipment. For the average weekend warrior who prefers conventional campsites with electrical hookups and shorter getaways, our standard 100Ah lithium battery offers a perfect balance of weight, cost, and dependable performance. Tailored to meet minimal power demands, it provides ample energy to run essential devices like lighting, fans, and phone chargers without the bulk of higher-capacity batteries.
For more avid adventurers embarking on extensive road trips to national parks or exploring off-grid on BLM land, where electrical hookups are few and far between, robust battery storage becomes essential. Our upgraded 300Ah lithium option ensures an uninterrupted power supply for your trailer’s lighting, ventilation, and crucial appliances like electric coolers. These higher-capacity systems allow you to stay unplugged longer and roam farther with confidence, knowing your power supply is both reliable and efficient.
The right battery size becomes an essential companion, ensuring power storage is tailored precisely to your needs so you can extend your trips as long as possible.
🔆 Lighting
-
Impact: Minimal draw.
-
Details: LED cabin and galley lights typically consume very little power (often under 1 amp total if all are on).
-
Battery Life: Negligible effect even over multiple nights — a 100Ah battery can run LED lights for days without noticeable drain.
💨 Vent Fan (e.g., MaxxFan)
-
Impact: Moderate draw.
-
Details: A MaxxFan at low to medium speed draws 0.2 to 1 amp; at full speed, closer to 3 amps.
-
Battery Life: Running overnight at low speed might use ~10–20Ah; significant over a few nights without recharge.
❄️ Electric Cooler (e.g., Dometic CFX3 35)
-
Impact: High draw over time.
-
Details: Draws 1–5 amps depending on conditions, ambient temp, and compressor cycle.
-
Battery Life: Can use 30–60Ah per day — a 100Ah battery may only last 1–2 days without solar support or recharge. A 300Ah battery offers 4–6 days depending on conditions.
🔌 USB Charging (Phones, Tablets, etc.)
-
Impact: Low to moderate.
-
Details: Each device typically draws 1–2 amps when charging.
-
Battery Life: Charging a couple of phones daily won’t make a major dent — maybe 5–10Ah/day total.
💻 Laptops, Cameras, Drone Batteries
-
Impact: Moderate, depending on usage.
-
Details: Inverter use adds inefficiency — charging camera or laptop batteries might draw 5–10Ah per session.
-
Battery Life: Occasional use is fine on 100Ah; frequent use is better matched to 300Ah + solar.
🔌 375W Inverter (for AC power)
-
Impact: Potentially high draw.
-
Details: Running AC appliances (coffee maker, CPAP, laptop charger) through the inverter uses extra energy due to conversion losses.
-
Battery Life: A 300W device running for one hour could consume 30–40Ah — better suited for 300Ah setups.
The Electric Fridge Factor: Sizing Up for Cooler Adventures
A key consideration that significantly impacts battery selection — briefly mentioned in the previous section — is the choice between a conventional ice cooler or an electric fridge-style cooler, such as the Dometic CFX-35. While the former relies on ice and no power, the latter offers the convenience of instantly chilled food and beverages on demand. Opting for one of our electric coolers may require upgrading to a larger battery, ensuring ample power to keep things cool throughout your journey without frequent ice runs in the nearest town or camp store. While we suggest a minimum of 100Ah for fridge use if you anticipate having to operate off the grid without solar power, or during overcast weekends, we strongly advise opting for the 300Ah option.

Harnessing the Power of the Sun: Exploring Solar Options
To complement our lithium battery lineup, we also offer a reliable and versatile 100-watt solar panel from Zamp Solar. Designed with backcountry durability and ease of use in mind, this portable panel allows you to recharge your batteries at camp, ensuring your trailer stays powered wherever you roam. Whether you’re parked deep in the pines or camped beneath open desert skies, solar gives you the freedom to stay longer and go farther, with clean, renewable energy always within reach.
☀️ Solar Charging in the Real World: 100W vs. 200W Panels
When it comes to recharging your trailer’s lithium battery, the size of your solar array plays a huge role in how long you can stay off-grid. While sunny skies are ideal, real-world performance varies with location, time of year, and shading — so it’s important to set expectations accordingly.
🔋 100W Solar Panel (Zamp Portable or Roof-Mounted)
-
Ideal For: Topping off a 100Ah battery on weekend trips, or offsetting daily draw from lights, fans, and occasional device charging.
-
Daily Output: On a clear day, a 100W panel can typically generate 30–40Ah of power.
-
What That Gets You: Enough to replenish a full day of moderate use — such as lights, a vent fan, and phone charging — but not enough to keep up with heavier loads like a fridge or inverter use for more than a couple of days.
-
Pairing: Best suited for a 100Ah battery and lighter-duty systems. For longer trips with an electric cooler or cloudy conditions, additional power storage or a second panel is recommended.
☀️ 200W Solar Array (Dual Panels or Upgraded System)
-
Ideal For: Serious off-grid travel with a 300Ah battery, electric fridge, and other active systems.
-
Daily Output: Typically yields 60–80Ah per day under good conditions.
-
What That Gets You: Enough to keep pace with heavier energy usage, including running a fridge continuously, charging multiple devices, and using a vent fan overnight — all while gradually recharging your battery bank.
-
Pairing: Strongly recommended for a 300Ah battery setup. Provides flexibility to stay out longer and charge back up even after a cloudy day or two.
⚡ Performance Note:
Solar output is most effective when panels are well-angled and exposed to full sunlight for several hours. Shade from trees, low sun angles in winter, and overcast skies can reduce output dramatically. That’s why we recommend combining a smart monitor like the Victron BMV-712 with solar — so you can see your power levels and solar gain in real time, helping you adapt as needed.
