Choose the Right Starting Point

Select the project track matching your technical stage, whether verifying factory capacity, starting an OEM program, or specifying a custom voltage architecture.

Compare Suppliers

Qualify the Manufacturing Facility

For procurement and engineering teams comparing battery suppliers. Review cell sourcing, assembly equipment, inspection steps, testing records, and production documentation.

Cell sourcing, assembly, and test records are auditable before order confirmation.Review Manufacturing Facility →
OEM / ODM

Start an OEM or ODM Program

For companies developing a new battery-powered product or replacing an existing pack. Define ownership, tooling, firmware, compliance responsibilities, sample stages, and production terms before quotation.

Battery Architecture

Define the Battery Architecture

For engineers who know the voltage, runtime, current profile, and mechanical envelope but need help selecting the pack configuration. Review cell series/parallel architecture, BMS communication, thermal management, and enclosure options.

Pre-Engineering FAQ

Provide your core operational constraints: operating voltage window, usable watt-hours, continuous and peak amperage, maximum enclosure dimensions, and host communication protocol. Our engineering team calculates the required cell count and configuration based on these variables.

Validation prototypes have no minimum order quantity. Custom builds utilizing standard tooling start at 100 units. Projects requiring dedicated injection molds, deep firmware modification, or third-party pack certifications typically scale from 300 units.

Using certified cells does not automatically convey certification to a finished battery pack. We supply UN38.3 test summaries and IEC documentation for our architectures, and coordinate third-party testing (e.g., UL 1973, IEC 62619) directly within the project schedule.
