“Been running 4 24v batteries in a 2S/2P 48V set up for a year now in an RV. So far so good. Have run them down to 30% on a few occasions and still very happy with purchase.”
Works as expected!!!Added to another pq 25.6v 100ah to my solar system for more capacity. Works great, no problems with these batteries!!!
FAQ
What size LiFePO4 battery do I need for my RV?
That depends on how much power you typically use per day. For many RV users running lights, fridge, fans, and TV overnight, a 12V 200Ah lithium battery usually covers things with some room to spare.
What capacity lithium battery is best for a 2-day RV motorhome trip?
For RV applications, a 12V Lithium battery is the most common and compatible choice. Based on typical daily power consumption (including a fridge, lights, water pump, and small electronics), you can expect to use around 2000Kw–3000Kw per day. Since Power Queen LiFePO₄ batteries are ideally discharged up to 80% of their capacity, you'll need a total capacity of around 200–300Ah to support a 2-day off-grid trip.
Can I use my existing RV charger with a lithium battery?
In most cases, yes. Just double-check that your charger supports LiFePO4 charging voltage (around 14.4V). If not, you may want to upgrade for faster and safer charging.
Will a lithium battery still work in cold weather?
You’ll still get good discharge performance down to –4°F. Just keep in mind that charging below freezing needs a battery with built-in low temp protection, Power Queen batteries include that.
Can I connect multiple LiFePO4 batteries in my RV?
Absolutely. Whether you’re trying to run a big inverter or just want more capacity, Power Queen batteries support series and parallel connections up to 4P4S.
How long do these RV lithium batteries typically last?
You’re looking at 4,000+ full cycles, which can be 10 years for most people. And yes, we cover them with a 5-year warranty.
