Custom Lithium-Ion Battery Design & Engineering Services

End-to-end bespoke battery pack design, proprietary BMS integration, thermal management, and rapid prototyping engineered for mission-critical OEM applications globally.

Precision-Engineered Custom Li-Ion Solutions for International Procurement

At Altertek, we specialize in high-reliability, engineered-to-order lithium-ion battery pack solutions. With over 15 years of hands-on electro-chemical and electronic engineering expertise, we partner with leading original equipment manufacturers (OEMs) across Europe, North America, and Asia-Pacific to power demanding subsea, electric mobility, industrial robotics, and stationary energy applications.

Our dedicated team handles the entire lifecycle — from mechanical design and thermal simulation to custom PCB hardware layout, software configuration, and full UN38.3 certification support. Every battery project is executed under rigorous ISO9001:2015 quality management standards in our UK facility.
