Spanish Startup BattBelt Raises €630,000 from BeABle Capital to Extend Battery Life

Madrid, Spain - In a move that could have significant implications for the renewable energy and electric vehicle sectors, the Spanish startup BattBelt has closed a €630,000 investment round led by BeABle Capital. The fresh capital will help the company scale its technology, which can extend the lifespan of electric batteries by up to 50% for e-mobility and stationary energy storage applications.

The timing of the deal is noteworthy, as Spain faces a pivotal decade in its energy transition. In 2024, renewable generation accounted for 56.8% of the country's total energy mix, up 10.3% from the prior year. Looking ahead, Spain's Integrated National Energy and Climate Plan aims to deploy 22.5GW of energy storage by 2030, combining batteries, pumped hydro, and thermal storage solutions.

According to consulting firm EY, Spain's battery market for the power grid is poised to more than double by 2029, surpassing €2 billion. The country is second only to the United States globally in battery storage project development, with 16GW planned through 2030 - 29% of the estimated 55GW worldwide.

"BattBelt's technology comes at a critical juncture as Spain accelerates its renewable energy transition," said Ana Garcia, a partner at BeABle Capital. "Extending battery life is key to unlocking more efficient, reliable, and clean energy storage solutions across sectors."

The investment also arrives as Europe's electric vehicle market continues its rapid ascent. Passenger EV sales grew 24% year-over-year in the first nine months of 2025, and nearly doubled in Spain over the same period, according to industry group ACEA. Analysts expect 2026 to be a pivotal year for mass EV adoption.

"Advancements in battery technology will be essential to support the surge in electric mobility and renewable energy storage," noted Maria Sanchez, BattBelt's CEO. "Our solution aims to maximize the lifetime value of these critical components, driving down costs and emissions."

With the fresh capital, BattBelt plans to accelerate the industrialization and deployment of its proprietary battery enhancement technology. The startup's innovations could have far-reaching implications, from bolstering Spain's renewable energy targets to supporting the electric vehicle revolution sweeping the continent.
