The cost of a 10 kWh battery can vary depending on several factors, such as the type of battery, the quality, the manufacturer, and any additional costs such as installation and shipping. Furthermore, market conditions and supply and demand can also influence prices.

As a guideline, you can expect the cost of a 10 kWh battery to range from a few thousand to several tens of thousands of euros. However, it is important to note that battery prices have decreased significantly over time and are expected to continue to fall as technology continues to develop and the market grows.

It is advisable to contact battery suppliers or specialized companies in this field to obtain specific price information. They can provide quotes based on your specific needs and requirements. Additionally, it is important to consider the warranty, lifespan, and performance of the battery when making a purchasing decision, not just the initial costs.

It is wise to conduct a thorough cost analysis and compare quotes from different suppliers to gain a good understanding of the total costs and return on investment. Also, keep in mind that there may be subsidies, tax benefits, or other financial incentives available that can help lower costs.
