Our custom process
From spec to production
Every custom battery project follows a structured engineering process, designed to reduce your time to market and eliminate surprises.
Discovery
We review your device specs, operating environment, runtime requirements and target markets.
Design
Our engineers select cells, design the BMS, determine the cell configuration, and produce mechanical drawings and firmware architecture.
Prototype
We build prototype packs at our Newberry campus for you to integrate and validate in your device. Fast iteration, direct feedback.
Certification
We support testing and certification for your target markets, keeping your project on schedule.
Production
Full production runs on our Newberry, Florida campus with in-house quality control, labeling and packaging, to your delivery schedule.
Customization options
Every dimension, engineered for you
We don't just relabel a standard product. Every custom Inspired Energy battery is engineered from the cell configuration up.
-
Cell configuration
Custom series and parallel cell arrangements to hit your voltage, capacity and discharge rate targets. We select from top-tier cell suppliers for your application.
-
Firmware & BMS
Custom BMS firmware parameters, charge profiles and communication objects, set for your OEM product line.
-
Connector & interface
Proprietary or standard connector systems, pinout configuration, and SMBus / I²C interface parameters matched to your device's design.
-
Enclosure & form factor
Custom injection-molded housings tooled in-house. We design and manufacture ourselves: no outsourcing, no tooling handoffs.
-
Labeling & branding
Your brand, regulatory markings and custom label design, produced on our in-house label line and applied before shipment.
-
Testing & certification
Testing and certification support for the market approvals your device needs, managed alongside the build so the schedule holds.
Why choose us
The vertical integration advantage
Many battery suppliers outsource tooling, PCB manufacturing, labeling and sometimes even assembly. At Inspired Energy, those steps happen on one campus, which means faster timelines, tighter quality control, and a single point of accountability for your program.
When your engineer has a question, our sales team in Newberry, Florida brings our engineers straight in: not a distributor, not an overseas factory, not a call center.
- No overseas manufacturing handoffsDesigned and built in the USA, on one campus: no offshore IP exposure, no waiting on an overseas factory.
- Faster prototyping cyclesIn-house tooling and PCB manufacturing means design changes do not wait on outside vendors.
- Top-tier cells, sourced directlyWe source cells only from globally recognized tier-1 suppliers.
- OEM focused, not consumer focusedOur entire operation is built around serving OEM device manufacturers.
