Lithium Battery Engineering & OEM Development

We provide end-to-end engineering support for OEMs developing custom lithium battery systems for demanding applications. From initial application requirements through production-ready design, we help clients select the right cell chemistry and format, develop battery architecture and custom BMS electronics, and engineer systems around real-world requirements including power, cycle life, temperature, vibration, environmental exposure, communications, safety, and regulatory compliance.

Our services include holistic battery system design, cell chemistry and cell selection, BMS circuit design and integration, CAN and data communications, and design-for-manufacturing support. Once the design and prototype are proven, we can connect clients with established contract manufacturing partners and help transition the product efficiently from engineering samples into scalable production.
