Why Choose BatterySpace for a Custom Battery Pack?

More Than 26 Years of Battery Experience

Our team has more than 26 years of experience in batteries, battery packs, chargers, protection circuits, and related power-system components.

30,000-Square-Foot U.S. Warehouse

Our Richmond, California warehouse stocks a large selection of battery cells, chargers, battery testing equipment, and accessories. Local inventory can help reduce component-sourcing time for qualified projects.

Two Battery Assembly Lines in the USA

We operate two battery assembly lines in Richmond, California. These lines support custom battery pack prototypes, small production runs, and urgent assembly orders.

Battery packs assembled at our California facility may use domestic or imported components depending on the project’s technical, regulatory, and sourcing requirements. Please tell us if your project has country-of-origin or domestic-sourcing restrictions.

Rapid Design Review and Prototyping

We can review your application requirements, recommend a suitable battery configuration, and develop prototypes for evaluation. The project timeline depends on cell availability, engineering requirements, tooling, testing, and certification needs.

In-House 3D-Printed Prototypes and Fixtures

We can produce 3D-printed cases, enclosures, and assembly fixtures with dimensions up to approximately 12 × 12 × 11.8 inches. This capability can help accelerate prototype evaluation before production tooling is considered.

Extensive Product Selection and Sourcing Capabilities

Through established manufacturer relationships, purchasing experience, and sourcing capabilities, BatterySpace can help customers identify suitable cells, protection circuits, chargers, connectors, enclosures, and accessories.

Private Labeling and Custom Packaging

Private-label and custom-packaging services are available for both small and large businesses. Customers may establish their own brand for qualifying production orders. Custom branding programs may require a minimum order of approximately 10,000 units, depending on the product and packaging requirements.

Battery Testing and Certification Support

BatterySpace can assist customers with arranging applicable testing and documentation for custom battery packs assembled by BatterySpace.

Available support may include:
