Custom battery packs are tailored power solutions designed to meet specific voltage, size, capacity, or environmental requirements. Off-the-shelf batteries often lack the precision needed for specialized applications like robotics, military gear, or industrial equipment. Custom packs ensure optimal performance, safety, and integration for your unique project.

Industries requiring high-performance, reliable power in demanding environments include:

• Defense & Aerospace: Rugged, explosion-proof packs for field equipment.
• Medical Devices: Compact, long-life batteries for portable diagnostics.
• Electric Vehicles (EVs): High-energy-density packs for automotive and fleet use.
• IoT & Wearables: Ultra-thin or flexible designs for space-constrained devices.

Our engineering team optimizes packs for:

• Temperature Resistance: Operate in -40°C to 60°C environments.
• Vibration/Shock Proofing: Ideal for automotive, mining, or aerospace.
• Safety Compliance: Certified explosion-proof (Ex ia/ib IIA/IIB), UL, CE, and UN38.3 standards.

Yes! We specialize in:

• Ultra-Thin Designs: Polymer lithium packs as slim as 0.4mm.
• Flexible Configurations: Curved, cylindrical, or irregular shapes.
• High-Capacity Solutions: Scalable 18650 or prismatic cell assemblies.

1. Consultation: Share your specs (voltage, capacity, size, environment).
2. Prototyping: Our 60+ R&D engineers design and test your pack.
3. Certification: Ensure compliance with global standards.
4. Production: Scalable manufacturing with strict quality control.

Prototyping typically takes 6–12 weeks, depending on complexity. Rush services are available for urgent projects.

Yes! We support low MOQs for prototypes and pilot runs, with seamless scaling to mass production.

Our packs meet below and we can work together on other certifications if needed.

• Safety: UL, CE, FCC, IEC62133.
• Transport: UN38.3.
• Explosion-Proof: Ex ia/ib IIA/IIB.

Absolutely. We embed advanced BMS for:

• Overcharge/over-discharge protection.
• Thermal management.
• Cell balancing and real-time monitoring.

• Longer Runtime: Optimized energy density for your application.
• Enhanced Safety: Built-in protections for extreme conditions.
• Space Efficiency: Perfect fit for your device’s design.

• 1,000+ Cycle Lifespan: Reduce replacement frequency.
• Recyclable Materials: Comply with EU RoHS and WEEE directives.
