Frequently Asked Questions
- How long will the PLB15 power my RV appliances?
- Runtime depends on your load. For example, a 100W device runs approximately 4.8 hours on a full charge. Calculate your specific needs by dividing the 480Wh capacity by your appliance's wattage. Many RV owners pair multiple batteries for extended off-grid camping.
- Can I connect the PLB15 to my existing RV solar setup?
- Yes. The PLB15 works with standard 12V solar charge controllers and MPPT chargers commonly used in RV systems. The integrated BMS ensures safe charging and prevents damage from overcharging.
- What's the advantage of LiFePO4 over the lead-acid battery my RV came with?
- LiFePO4 offers significantly longer lifespan (3,000+ cycles vs. 300-500 for lead-acid), weighs 60% less, charges faster, and maintains consistent voltage throughout the discharge cycle. No maintenance is required, and it handles partial discharges without damage.
