Got Questions?

  • Q.

    Can you customize battery size and shape for my device?

    Yes. We offer full customization for LiPo batteries — thickness, width, and length can be adjusted to fit your device’s available space. Minimum thickness can go down to 3mm.

  • Q.

    Do you provide certification support for custom batteries?

    Yes. We help your custom batteries pass necessary certifications including IEC62133, UL, UN38.3, CE, KC, and more — tailored to your target markets.

  • Q.

    What types of batteries can you customize?

    We offer a wide range of custom lithium battery solutions, including LiPo (polymer) batteries, cylindrical Li-ion cells (such as 18650 and 21700), and complete battery packs with integrated BMS. Customization covers dimensions, capacity, voltage, discharge rate, wiring, connectors, enclosures, and communication protocols (SMBus, I²C, CAN, etc.). Whether you need a thin flexible battery for a wearable device or a high-power pack for industrial equipment, we can tailor the solution to your specifications.

  • Q.

    Can you provide samples before mass production?

    Yes, we support sample development and prototyping. After confirming your technical requirements, our engineering team will produce sample batches for testing and validation. This allows you to verify fit, performance, and safety before moving to full-scale production. Sample lead times depend on the complexity of the design but typically range from 2 to 4 weeks.

  • Q.

    How do you ensure battery safety and quality?

    Safety and quality are built into every step of our process. We start with rigorous cell selection, followed by multi-layer protection designs including overcharge, over-discharge, overcurrent, and short circuit protection. Each production batch goes through more than 60 quality inspection checkpoints, from incoming materials to finished packs. We also conduct aging tests and performance validation to ensure consistency and reliability before shipment.
