Build Your Own 15kWh Energy Storage System – Cost-Effective DIY Battery Kit with BMS
This DIY battery kit is an ideal solution for users looking to build a reliable and high-capacity 15kWh home energy storage system. It includes all essential components—such as a high-quality Battery Management System (BMS)—with only the battery cells left to be added. We offer brand new Grade A lithium battery cells upon request to complete your setup.
Compared to factory-assembled units, this kit offers significant cost savings without compromising on performance. It’s designed for flexibility, allowing for easy battery cell replacement—something not typically possible with sealed, pre-built systems. The included BMS is highly reliable and on par with those used in many commercial battery storage units.
Perfect for solar energy storage, off-grid setups, or backup power systems, this kit gives you the freedom to build a powerful solution tailored to your specific needs—at a fraction of the price.
