24v Batteries for RV campers

When it comes to choosing between a 12V and 24V battery system for your RV, there are important considerations to keep in mind. Let’s explore the advantages of each:

1. 12V System:
   • Compatibility: Most RV appliances, such as lights and refrigerators, operate on 12 volts. A 12V system ensures compatibility without the need for voltage converters.
   • Charging Efficiency: Charging RV batteries while driving is straightforward with a 12V system. You can link it to the vehicle’s 12V starting battery using a DC-DC charger.
   • Common Choice: Smaller RVs with limited space and power needs often benefit from a 12V system.
2. 24V System:
   • Efficiency: A 24V system draws less current for the same power output, resulting in reduced heat generation and power wastage. Smaller wires can be used due to lower current flow, improving overall performance efficiency.
   • Cost-Effective: Smaller and less expensive solar charge controllers can be used with a 24V system, making it ideal for RVs equipped with solar panels.
   • Larger RVs: Larger RVs with higher power demands may find the efficiency and cost savings of a 24V system advantageous.

Remember that your choice should align with your specific RV setup and power requirements. Whether you opt for 12V or 24V, consider upgrading to LiFePO4 batteries for enhanced performance and reliability

48v Batteries for RV campers

When considering 48V batteries for your RV, it’s essential to understand the benefits and compatibility. While 48V systems are less common in RVs, they offer advantages for specific setups:

1. Energy Density: Lithium batteries at 48V provide impressive energy density, allowing them to be lighter and smaller while storing more power.
2. Weight Savings: Compared to lead-acid batteries, 48V lithium batteries weigh significantly less, making them ideal for weight-conscious RVers.
3. Charging Efficiency: Lithium batteries charge faster and have a longer lifespan, enhancing overall performance.
4. Solar Integration: If you have a large solar array (such as 2,280 watts), a 48V lithium system can efficiently store the energy generated.

Here are some 48V lithium battery options for RVs:

• Renogy 48V 50Ah LiFePO4 Battery:
  • Built-in BMS
  • Suitable for RVs, campers, vans, marine applications, and off-grid setups.

Is it OK to leave a LiFePO4 battery on the charger?

Yes, it’s generally safe to leave a LiFePO4 battery on the charger. Unlike some other battery types, LiFePO4 batteries are less prone to overcharging. However, consider the following tips:

1. Smart Chargers: Use a charger specifically designed for lithium batteries. Smart chargers adjust the charging process based on the battery’s needs.
2. BMS Protection: LiFePO4 batteries have a built-in Battery Management System (BMS) that protects against overcharging and over-discharging. Trust the BMS to manage the charging process.
3. Avoid Prolonged Overcharging: While it’s safe to leave the battery connected, avoid excessively long periods of overcharging.

How big of a lithium battery do I need for RV?

When selecting a lithium battery for your RV, consider capacity, usage, weight, and space. Lithium batteries range from 50Ah to 400Ah, with lighter weights than lead-acid counterparts. Assess your daily energy needs for appliances like lights and fridges. Remember, higher capacity means more energy but may also be heavier, so choose wisely based on your specific requirements.

1. Capacity: Lithium batteries come in various capacities, typically measured in amp-hours (Ah). Common sizes include 50Ah, 100Ah, 200Ah, and 400Ah.
2. Usage: Assess your power needs. Calculate the daily energy consumption of your appliances (lights, fridge, devices).
3. Weight: Lithium batteries are lighter than lead-acid batteries. For example, a 100Ah lithium battery weighs around 30 pounds, while a lead-acid battery of the same capacity weighs about 70 pounds.
4. Space: Check the physical dimensions to ensure it fits in your RV battery compartment.

Remember, larger capacity batteries provide more energy but may be heavier. Choose based on your specific requirements!

How long will a 100ah lithium battery last in RV?

A 100Ah lithium battery can last anywhere from 120 hours (running a 10W appliance) to 36 minutes (running a 2,000W appliance). Specifically, a 100Ah 12V battery has a capacity of 1.2 kWh, which is more than 2% of the capacity of the Tesla Model 3 car battery. To calculate how long it will run any appliance, you can use the formula:

Battery Life (hours)= Battery Capacity (Wh) / Appliance Power (W)​

For example:

• Running a 400W appliance: Approximately 2 hours and 30 minutes.
• Running a 100W appliance: Around 12 hours.

Remember that actual usage depends on the specific appliance and your power needs!
