Custom Batteries
Custom battery design and manufacturing for OEMs. Lithium-ion hard pack and soft pack solutions tailored to application requirements.
Custom Battery Engineering
Custom batteries combine materials, cell design, protection circuitry, and manufacturing processes around the requirements of a specific application. The right design depends on operating environment, available space, discharge profile, safety requirements, and production goals.
A custom battery is built around a cell, which is the basic unit of a battery. The cell contains an anode, a cathode, and an electrolyte. The anode and cathode are typically made of different materials that allow for the flow of electrons between them, while the electrolyte allows ions to move between the electrodes.
If your product requires longer life, improved efficiency, or a specialized form factor, US Micro Products can help define and manufacture a battery pack appropriate for the application.
Chemistry
Lithium-ion, nickel-cadmium, and other chemistries selected around application needs.
Custom Design
Size, weight, and voltage output optimized for your application.
Manufacturing
Optimized assembly and quality control for reliable performance.
How Custom Batteries Work
A custom battery is built around a cell — the basic unit containing an anode, cathode, and electrolyte — and then configured around your product requirements.
Chemistry
Lithium-ion supports high energy density and long cycle life. Nickel-cadmium supports high discharge rates and deep discharge tolerance. We help select chemistry based on the application profile.
Design
Size, weight, and voltage output tailored to your application — from tiny medical implant batteries to larger packs for electric vehicles and industrial equipment.
Manufacturing
Assembly processes and quality controls are defined to support performance, reliability, and safety for the intended use case.

When Do You Need a Custom Battery?
Unique Power Needs
Commercially available batteries cannot meet your specific power requirements.
Size & Shape Constraints
Your battery has size and shape limitations that require a custom form factor to fit within the available space.
Special Features
You require a high discharge rate, long cycle life, or other performance characteristics beyond standard batteries.
Lithium Battery Pack Types
We design and manufacture two types of lithium battery packs to match your product architecture.
Hard Pack
Removable from the system so the user can replace and recharge independently.
Common Applications
- Digital cameras
- Doorbells
- IoT devices
Soft Pack
Fixed pack in the system that cannot be removed — the system charges it directly.
Common Applications
- Mobile phones
- Wearable devices
- Bluetooth peripherals
- GPS devices
- Laptops
