Frequently Asked Questions
Q: Do these really last 10 years? Absolutely. LiFePO4 chemistry delivers 4,000+ cycles. Real users from 2019 report batteries still test above 95% capacity today.
Q: Will these work with my RV’s current setup? If your RV is newer than 2015, yes—check for LiFePO4 setting on your converter. Older RVs need a DC-DC charger ($150) between alternator and battery.
Q: What’s the catch at these prices? Email support instead of phone support. The 5-year warranty covers everything, you just wait 24 hours for responses. Same cells as brands costing 3x more—you’re buying direct, not through RV dealers who mark everything up 40-50%.
