Lithium Polymer Batteries
EI Sales delivers lithium polymer batteries engineered for performance-driven OEM programs across medical, aerospace, industrial, and specialty vehicle sectors. These solutions fit projects where weight, space, and battery geometry directly influence product feasibility. We collaborate with design engineers to specify application-ready power systems that align cleanly with advanced mechanical and electrical requirements.
Lightweight Power for Compact Designs
These batteries feature high energy density in a lightweight, flat format. They are well-suited for compact and mobile technologies. Their pouch-cell construction eliminates rigid casing constraints, enabling thinner profiles and lower overall weight without compromising output. They’re a strong match for portable instrumentation, handheld controls, and embedded systems with limited real estate.
Their structure also introduces flexibility during product development. Engineers can explore slimmer enclosures, reduce chassis weight, and position batteries in constrained areas without overhauling circuit layout. In wearable and handheld electronics, that flexibility enhances both device performance and ergonomics.
Our team helps OEMs select lithium polymer batteries that align precisely with mechanical fit and power needs. Our team gets involved early to guide options based on footprint, thickness, and target capacity.
Custom Packs with Full Design Support
EI Sales partners with engineering teams to develop lithium polymer battery packs tailored to meet detailed performance, safety, and integration goals. We offer input on cell format, protection circuitry, connectors, and housing design, ensuring each pack fits seamlessly into the overall assembly.
Design assistance includes options like temperature sensors, communications protocols, charge balancing, and shielding. Our team applies its manufacturing experience during design reviews, helping to avoid delays tied to compliance gaps or late-stage changes.
We handle both prototype development and production builds. For time-sensitive programs, we prioritize short lead times and fast response so projects continue to progress without setbacks to quality or regulatory readiness.
Certified for Regulated Industries
Lithium polymer batteries sourced through EI Sales meet qualifications for highly regulated sectors such as aerospace, medical, and defense. We guide OEMs in selecting batteries aligned to ISO 13485, AS9100, and other compliance frameworks that require clear documentation and verifiable control.
Traceability and documentation remain consistent from evaluation through final production. Our team collaborates throughout the lifecycle, helping teams validate designs during audits and regulatory submissions. Suppliers adhere to strict process controls, and we stay involved to maintain alignment across all program milestones.
For applications involving surgical tools, diagnostic systems, or airborne platforms, we assist in specifying batteries that meet both technical expectations and industry benchmarks.
Flexible Cell Sizes and Configurations
These batteries come in a broad range of dimensions and capacities. The pouch-style design supports tighter mechanical integration, especially in applications where rigid batteries would restrict layout or limit available space.
This configuration suits low-profile devices without limiting energy output. It also enhances placement options around heat sources, antennas, and structural elements that otherwise constrain layout flexibility.
We work closely with engineers to match capacity, footprint, thickness, and connector type to the specific requirements of the design. We handle both off-the-shelf and custom sizes, supporting projects that demand specialized geometry or higher storage density. This versatility gives OEMs more control over internal design without trading off reliability.
