Ideal for the cottage: The EcoFlow DELTA 2 Max backup power supply is 24 thousand cheaper than its original price!

Battery stations are one of those categories where it pays to wait. EcoFlow DELTA 2 Max was launched in 2023 for fifty thousand, back then, it set the bar for both performance and quality. Today, for 26 thousand, you can get the same hardware on Heureka — and it’s precisely the improved second-generation LFP cells that make this station one of the most sensible purchases you can make right now in the backup power category.

Quick summary:
✅ Makes sense for cottage owners, people dealing with power outages, or balcony solar systems — a capacity of 2 kWh with 2,400 W of power will cover most household appliances.
⚠️ Consider if you need more — the capacity can be expanded up to 6,144 Wh by adding two extra batteries, but each costs additional money.
💡 For 25,990 CZK you get an LFP battery with a lifespan of 3,000 cycles and charging from zero to 80% in 53 minutes from AC

Why LFP Cells Change the Entire Equation

Older battery stations — including the first generation — used NMC cells, which start to noticeably lose capacity after 500–800 cycles. The second generation switched to LiFePO4, which guarantees 3,000 cycles to 80% capacity. With daily charging and discharging, this amounts to roughly ten years of operation. EcoFlow also added a five-year warranty, so the first few years are contractually covered.

What This Can Power in Practice

Output power 2,400 W continuously, 4,800 W peak — this means a refrigerator, TV, lights, laptop, and mobile chargers simultaneously without issues. The patented X-Boost can also handle appliances up to 3,100 W, such as an electric kettle or a hairdryer. And if you have balcony solar panels or are considering acquiring them, DELTA 2 Max connects directly to them via the PowerStream system — it stores surpluses from the day and uses them in the evening.

Are you dealing with backup power at home or at the cottage, or are you more interested in balcony solar systems?
