Insights

Strategic partnerships Custom Power has recent and notable alliance activity with SDO Associates and Volklec Limited, signaling a proactive stance in expanding defense-focused battery capabilities and sovereign energy solutions which creates cross-selling and co-marketing opportunities with defense contractors and system integrators.

Defense market growth Frequent defense sector news and UK defense collaboration, including UK sovereign energy solutions, position Custom Power to pursue additional defense prime contractors, military OEMs, and government-funded programs requiring reliable, rugged battery systems and ITAR-compliant supply chains.

Global manufacturing With production facilities across the USA and Europe and a track record of customizing COTS and bespoke battery packs, there is a strong value proposition for multinational programs and regionalized logistics, enabling faster delivery timelines and localized support for global customers.

Quality and compliance ISO 9001:2015, ISO 14001, ISO 45001, AS9100, RoHS, and ITAR registrations highlight a robust quality and compliance framework, which can reduce risk for customers in regulated industries such as medical, aerospace, and defense, aiding in tender approvals and audits.

Growth potential Revenue range and recent leadership changes indicate scale-up potential; combined with a strategic focus on critical applications (medical, aerospace, defense, energy), opportunities exist to upsell higher-value power systems, extended life-cycle services, and integrated battery management solutions to existing customers and similar market actors.
