CUSTOM BATTERY FAQ

Common Questions About Custom Battery Projects

Direct answers about project inputs, battery design, BMS, prototypes, certification, manufacturing, quality control and support.

CLEAR ANSWERS, CORRECT CONTEXT

Understand the usual process without treating every project as identical.

These answers explain how Stellova normally approaches custom battery work. Project-specific scope, timing, testing and certification are confirmed only after requirements review.

FREQUENTLY ASKED QUESTIONS

Start with the questions most teams ask.

Browse common questions about starting a project, customization, samples, quotations, delivery, quality and support. Project-specific details are confirmed during requirements review.

01
PROJECT START

What information do you need to review a project?

Useful starting inputs include the application, nominal voltage, load profile, required runtime, available space, charging method, operating environment, communication needs and target market. Missing values can be clarified during requirements review.

02
PROJECT START

Can we start a discussion without a complete battery specification?

Yes. You can start by sharing the equipment application, any available battery information and the main problem you need to solve. Photos, drawings, an existing specification or preliminary operating data can help. Missing technical details can be clarified during requirements review.

03
QUOTATION

What information is needed for a quotation?

For an initial review, share the application, available specifications, project stage and expected quantities. A formal quotation may require confirmation of voltage, capacity or runtime, continuous and peak loads, dimensions, charging method, communication, operating environment, validation and certification requirements. Pricing is based on the agreed configuration and project scope.

04
CUSTOMIZATION

Do you only change voltage and capacity?

No. A custom battery system may include chemistry and cell selection, electrical architecture, BMS logic, communication, enclosure, connectors, thermal strategy, charger coordination, validation and certification planning.

05
REPLACEMENT & INTEGRATION

Can you develop a replacement battery while retaining our existing connectors or communication interface?

This can be evaluated after reviewing the existing battery and equipment requirements. Compatibility checks may include dimensions, mounting, connector pin assignments, voltage limits, charger behavior, communication protocols and protection logic. A matching connector alone does not establish compatibility; the proposed replacement must be validated with the equipment.

06
BMS & COMMUNICATION

Can the battery communicate with our product?

Yes, when required. The battery and BMS can be developed around interfaces such as CAN, RS485 or RS232, subject to the host protocol, control requirements and agreed project scope.

07
PROTOTYPES

Do you support engineering samples and pilot builds?

Yes. Stellova coordinates sample production and testing with qualified production partners. Prototype scope and acceptance criteria are defined for the project before release.

08
ORDER QUANTITIES

Is there a minimum order quantity for samples and production?

Sample quantities and production minimums are reviewed for each project. They depend on the cell and component selection, custom tooling, development work and manufacturing requirements. Share your prototype quantity and expected production volume so the applicable requirements can be confirmed.

09
LEAD TIMES

How are prototype and production lead times determined?

Lead time depends on requirements approval, design complexity, component availability, tooling, testing and any applicable certification activities. Prototype and production schedules are reviewed separately. The delivery schedule is confirmed against the agreed scope and current material availability.

10
CERTIFICATION

Can you support UN38.3, IEC or UL requirements?

Stellova can directly manage certification work within the agreed project scope. The exact standard, evidence, laboratory route, schedule and cost depend on the battery, application and destination market.

11
PRODUCTION

Does Stellova manufacture every battery in an owned factory?

Stellova manages customer requirements, engineering and projects, and coordinates production through qualified long-term or associated production resources selected for the project. Stellova personnel perform production quality checks and provide reports.

12
QUALITY

How is production quality controlled?

Production readiness, incoming and in-process checks, end-of-line testing, sampling, traceability and release records are defined according to the project. Stellova personnel perform inspections and provide the agreed quality report.

13
CONFIDENTIALITY

How should we handle confidential drawings and project information? Can an NDA be arranged?

If your project requires confidentiality terms, raise this before sending sensitive drawings or technical files. NDA requirements can be reviewed, and any agreement must be accepted by both parties before protected information is exchanged. For the initial discussion, share only the information needed to assess the application and project scope.

14
SUPPORT

Who provides technical support after delivery?

Stellova provides direct customer-facing technical support and coordinates any required engineering or production follow-up with the relevant project partners.

STILL HAVE A PROJECT QUESTION?

Ask it in the context of your product.

A useful answer depends on the application, operating profile and integration constraints.
