Electrical duty
Nominal voltage, operating window, continuous current, peak duration, runtime and charging method must agree.
OEM / ODM battery engineering
Custom sodium-ion battery packs built around the equipment—not a generic enclosure.
A structured development path from application requirements and cell qualification through electrical architecture, BMS, mechanical integration, interfaces, testing and supply planning.
Electrical + mechanical co-designBMS and interface planningPrototype → qualification → supply
Application first
A voltage and capacity request is not yet a complete battery-pack specification.
The pack must support the real load while fitting the product, communicating with the host, remaining serviceable and following the intended compliance path. The development scope begins by closing those interfaces.
Mechanical envelope
Space, orientation, mounting, connectors, cable exits, impact, ingress and thermal context shape the architecture.
Control and protection
BMS functions, sensing, balancing, communication and host-control responsibilities must be defined.
Commercial pathway
Prototype quantity, validation responsibility, certification, annual demand and change control affect development planning.
Engineering pathway
Connect cell selection to equipment-level acceptance.
The pack is developed through controlled gates so that electrical, mechanical and commercial decisions remain traceable as the project matures.

01
Industrial equipment
Application-specific power for machines, controls and mobile industrial systems.
02
Robotics and automation
Battery packs shaped by peak current, duty cycle, charging access and communication.
03
Outdoor electronics
Systems requiring coordinated enclosure, connector and environmental decisions.
04
Backup power modules
Defined standby, readiness, runtime and host-interface requirements.
05
Specialty mobility
Projects where packaging, mass, current and mechanical retention must be balanced.
06
OEM energy products
Custom modules or packs intended for integration into a larger branded system.
Evidence & decision boundary
Every pack specification inherits dependencies from the selected cell.
Cell documents, sample measurements, BMS settings, pack architecture and application tests are not interchangeable. Each performance statement must identify which level was evaluated and under what conditions.

Technical FAQ
Questions to answer before selection.
These answers establish the review process. Product specifications and commercial terms require project confirmation.
What information is needed for a custom battery pack?+
Provide the application, voltage range, runtime, continuous and peak current, charging method, available space, environment, interfaces, compliance needs and quantity.
Can you build a pack using 32700 sodium-ion cells?+
Yes, subject to cell qualification and review of the electrical topology, current, enclosure, BMS, interfaces and project requirements.
Does a custom pack include the BMS?+
BMS selection and integration can be part of the project. Required protection, sensing, balancing, communication and host-control responsibilities must be defined.
Can you copy an existing lithium battery pack?+
An existing pack can be used as a dimensional or interface reference, but chemistry, voltage behavior, charging, protection and compliance must be re-evaluated rather than copied blindly.
What is the minimum order quantity?+
Prototype and production quantities depend on cell availability, engineering scope, tooling, compliance and supply planning. Submit the expected sample and annual quantities for review.
Do you provide certification?+
The compliance pathway can be planned with the pack project. Applicable standards, test responsibility, target markets and final configuration must be confirmed first.
