Full-Service Custom Battery Pack Manufacturer

We are a full-service custom battery manufacturer with full design and engineering capabilities. Our team has extensive experience with lithium-ion, lithium polymer, nickel metal hydride, nickel cadmium, lithium primary, and alkaline battery packs and assemblies. On all projects, we work closely with customers from the first design concept through prototyping and testing to large-scale manufacturing from our facilities in the U.S. and China.

Most lithium and NiMH custom battery packs require a BMS system (battery management system), which will manage and maintain each cell, improve battery utilization through balancing, prevent battery overcharge and discharge, pro-long battery life, display a charge status (fuel gauge), and can even include a module to record the battery's history.

Epec's technical team can support every part of the process, including 3D construction and drawing design, hardware/enclosure creation, and smart battery management system design and manufacturing using I2C, SMBus, RS485, RS232 or CANBUS protocols.


Our custom battery packs are manufactured for various applications in the medical, military, aerospace, and portable devices industries.

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
