We Do Not Just Assemble.We Engineer.
33 years of solving real application challenges has produced an engineering process that starts before the first cell is chosen and does not end until the pack ships.
Engineering First, Always
At SES, every capability we have, in cell chemistry, pack architecture, BMS integration, and protection design, was developed in response to a real problem, from a real customer, in a sector where getting it wrong has consequences.
We do not build to a catalogue. We build your application. That distinction is what separates a battery that performs in the field from one that only looks right on paper.
Cell Technology & Selection
18650, 21700, pouch, and prismatic formats — evaluated and selected per application load, thermal envelope, and cycle life target.
- Capacity consistency testing
- Internal resistance evaluation
- Thermal behaviour analysis
- Self-discharge verification
Cell Technology & Selection
Every engagement starts with an application review — voltage, current draw, form factor, operating environment — before a single cell is chosen.
- Medical-grade configs
- Industrial ruggedised
- Compact wearable
- IoT long-standby
BMS Integration
Protection and communication logic designed around overcharge, over-discharge, short-circuit, and thermal fault conditions.
- SMBus v1.1
- I2C
- NTC thermistor
- Cell balancing
Protection Engineering
Multi-layer protection from cell level through pack level — matched to the physical and environmental demands of the application.
- PCBA-protected configs
- Ingress protection
- Cycle life testing
Compliance Documentation
Structured documentation at every stage — designed to support your regulatory pathway, not created retrospectively.
- IEC 62133 records
- CE marking support
- FDA docs
- CDSCO support
Prototype to Production
Low MOQ prototyping through controlled scale-up — the same facility, the same team, and full batch traceability throughout.
- Low MOQ prototyping
- Pilot batch support
- Controlled scale-up
- Batch traceability
