Safety, Certification and Shipping
Finished packs include protection against over-charge, over-discharge, over-current and short circuit, and are provided with UN38.3, IEC 62133, CE, RoHS, REACH and MSDS documentation. Where an application prioritizes intrinsic safety, very wide temperature tolerance or lower cost, our engineers may recommend a NiMH battery packبدلًا من ذلك.
Frequently Asked Questions
Q1: Which devices use custom lithium-ion packs?Typical devices include cordless power tools, flashlights and portable scanners, electric bicycles and scooters, medical and handheld devices, and small energy-storage systems.
Q2: Can you match a specific voltage, capacity and size?Yes. Packs are built from 18650/21700 cells in the required series/parallel layout and shaped to fit the device housing.
Q3: What protection is included in a pack?Packs include a PCM/BMS for over-charge, over-discharge, over-current and short-circuit protection, with optional NTC temperature sensing.
Q4: Which certifications are available?We provide UN38.3, IEC 62133, CE, RoHS, REACH and MSDS documentation to support compliance and international shipping.
Q5: How do I choose between lithium and NiMH packs?Lithium offers higher energy density and lighter weight; NiMH offers intrinsic safety, very wide temperature tolerance and lower cost. We recommend the chemistry that best fits the device.
Q6: How do I request a custom pack and what is the MOQ?Send your voltage, capacity, maximum current, dimensions, connector and certification needs; custom packs are project-based with flexible MOQ and a quotation within 24 hours.
