Your Battery Needs, Our Expert Solutions.
From Concept Design to Reliable Pack Production
We understand the real friction in custom battery sourcing: unpredicted manufacturing delays, rigid lead times, and superficial tech support that leaves your engineering team stranded.
Saphiion designs and manufactures custom OEM battery packs covering NMC batteries, long-life LiFePO4 packs, and cold-resilient Sodium-ion (Na-ion) battery packs. Integrated with smart BMS supporting CANbus, RS485, or Bluetooth, our battery packs are built for reliable performance. We work directly with your team to deliver certified power solutions on clear schedules, backed by hands-on engineering support from prototype to production.
Efficient, Scalable, and Precise: Automatic Production Process
- Reduce costs without sacrificing quality
- Shorten lead times, delivering your custom battery packs faster
- Maintain consistent, high-quality standards across every battery packs

Empowering Your Growth Through Engineering Partnership.
With 12+ years of specialized battery engineering experience, we do more than just assemble battery packs. We partner with OEMs and tech innovators to turn complex power concepts into fully validated, scalable battery systems.
Your success defines ours. We build long-term partnerships grounded in technical transparency, predictable manufacturing, and shared growth, supporting your project from initial design through high-volume production.
Finding the optimal power architecture shouldn’t slow down your R&D. Our engineering team offers direct design-for-manufacturability (DFM) advice, helping you select the right cell chemistries, mechanical layouts, and BMS protocols to save time and optimize lifecycle cost.
System safety and thermal stability are non-negotiable. We assist with proactive risk assessments, cell selection, lifecycle modeling, and rigorous pre-test protocols to prevent safety hazards and ensure long-term field reliability.
We streamline your path to market. Our team manages compliance requirements, guiding your battery packs through UN38.3, CE, UL (e.g., UL 2054/UL 2271) and IEC 62133 certifications so you can deploy globally with complete peace of mind.
Tailored battery solutions to meet your unique needs that vow your success.

Tailored Chemistries. Advanced BMS Safety. Global Pack Compliance.
Powered by 12+ years of battery pack engineering expertise, Saphiion delivers validated, custom-built power systems for demanding OEM/ODM applications worldwide.
Direct-to-Engineer Communication
Work directly with pack engineers from day one. We will reponse your demand within 24 hours, evaluating system voltage windows, continuous/peak discharge C-rates, physical space constraints, and connector selection to eliminate lost-in-translation delays.
Tier-1 Grade-A Cells
Exclusive sourcing of brand-new, Grade-A cells from certified tier-1 manufacturers (LG, Samsung, Panasonic, REPT, EVE, BAK, Hi-Na). Every incoming batch undergoes strict automated capacity grading, IR matching, and cell sorting to guarantee long cycle life and pack consistency.
Custom Smart BMS
Smart BMS architecture featuring multi-channel NTC thermistors, active/passive cell balancing, customizable overcurrent/overvoltage protection logic, and reliable protocol integration tailored specifically to your dynamic load profile.
Rapid Prototyping & Scaling
Built for high-complexity OEM/ODM scaling with less delivery surprises. We deliver functional prototype samples in 2 to 3 weeks (including 3D-printed enclosure fitting and spot/laser-welded sample assembly) and move to full certified volume production within 4 to 6 weeks.
Safety Certification
Built-in compliance engineering to streamline market entry. We design battery housing and protection systems to pass UN 4G dangerous goods packaging standards, UN38.3 transport safety clearance, and international safety certifications (CE, IEC 62133, UL 2271) with complete test documentation.
After-Sales Lifecycle Support
100% comprehensive testing on every battery pack before dispatch, including hi-pot insulation safety checks, BMS functional validation, and full charge-discharge aging cycles. Backed by clear warranty terms, 48-hour remote telemetry troubleshooting, and formal Root-Cause Analysis (RCA) reporting.
