Real-life example
Stefanos in Kalamata had an AGM battery that failed after 3 years. He replaced it with a Pytes V5 LiFePO4 5kWh. Cost: €2,800. The AGM batteries had cost him €1,200 every 3 years. With the Pytes: 10-year warranty, 6,000 cycles, 0 replacements.
💡 Tip: Don't just compare the initial price. Compare price/kWh and lifetime cost over 10 years. LiFePO4 is always cheaper in the long run.
