Start with the operating profile
Assess energy and power needs, operating voltage, duty cycle, temperature range and space constraints. An agreed engagement can include initial sizing, a concept assessment and an evaluation plan.

Battery Engineering, Custom Pack Design & Prototype Support
Bring us your application requirements. AuroraCell supports electrical sizing, mechanical design, prototype assembly and inverter or PCS integration, combining in-house work with specialist engineering partners.
A service built around your projectFeasibility & sizing Mechanical & pack design Electrical integration
From requirements to defined engineering outputs.
Develop the battery assembly
Support cell configuration, mechanical or CAD design, connection concepts and prototype assembly. Work can be delivered in-house, with partners, or as a coordinated combination.
Connect the battery to the application
Support inverter and PCS integration. Specialist partners provide BMS configuration, BMS hardware work and control-system adaptation according to the agreed project scope.
Clear responsibilities
One coordinated project. The right expertise.
| Work area | Delivery approach |
|---|---|
| Electrical sizing and mechanical / CAD design | In-house engineering and specialist partners |
| Prototype assembly and inverter / PCS integration | In-house work and partner delivery, depending on scope |
| BMS configuration and BMS hardware | Specialist partner delivery |
| Laboratory testing and commissioning | Specialist partner delivery |
AuroraCell coordinates the agreed scope. The project proposal identifies deliverables, responsibilities and relevant specialist partners.

Two requirements. Two different solutions.
Residential battery around a specified cell
A customer specifies a cell for a residential storage solution. AuroraCell handles the technical work, coordinates pack design and prototypes, and supports qualification and compliance activities with specialist partners. The scope is agreed around the intended application.
Custom welded 12V battery for a customer BMS
A customer needs a welded battery assembly for use with their own BMS. AuroraCell organises cell sourcing and welded connections, and coordinates applicable testing, certification activities, transport, import and EU compliance documentation.
Qualification & compliance support
Plan evaluation into the project.
A prototype is a step towards a qualified product. We support evaluation planning and coordinate applicable testing, certification activities and documentation with specialist partners.
The required work depends on the battery design, intended use and target market. We agree the route and responsibilities as part of the project scope.
An engagement with a clear scopeDefine Agree Progress
Know what is included before work begins.
Requirements and boundaries
Establish the application, interfaces, intended operating conditions, development stage and target quantities.
Outputs and responsibilities
Specify the required calculations, design documents, prototype quantities or evaluation activities, together with the delivery team and milestones.
Review and next steps
Review results against the agreed requirements and coordinate the next stage of development, qualification or supply.
Before you start
Custom battery project questions.
Is custom engineering included in a cell purchase?
Product selection and application support are included with cell purchases. Customised batteries, prototypes, pack development and project-specific integration are separately scoped and quoted.
Can you work with a cell or BMS we have already selected?
Yes. We can assess a customer-specified cell and develop an agreed scope around a customer BMS. Interface requirements and suitability are reviewed before committing to a design.
Can you support a technology other than sodium-ion?
Yes. We bring particular sodium-ion expertise, while remaining chemistry-independent in our technical recommendations.
