Justin Lopas, co-founder and COO of Base Power, appeared in an August 2026 interview at the company's Austin factory to discuss the launch of Base Core, a home battery system, and a $1 billion Series D funding round that valued the company at $13 billion post-money. The round was led by Ribbit, Addition, Valor Equity Partners, and JPMorganChase's Strategic Investment Group, with existing investors re-investing, bringing total capital raised past $2.5 billion. Lopas described Base Core as the largest standalone home battery on the market, offering 40 or 80 kWh capacity, and said the company aims to produce about 4,000 units per week by the end of the year. In the interview, Lopas explained that Base Power's service can be offered without a battery, allowing customers to purchase electricity in retail choice markets like Texas. He contrasted Base Core with typical home batteries, stating that most competitors are paired with solar, are smaller, wall-mounted, expensive, and not focused on grid support. He also noted that Base Power designed its own manufacturing execution system software to control robots and traceability on the factory line.
