UN38.3 Battery Certification Explained: What You Need to Know

UN38.3 refers to Section 38.3 of the United Nations Manual of Tests and Criteria. The standard ensures that lithium-ion and lithium metal batteries can safely withstand thermal, mechanical, and electrical stresses encountered during global transport without: Leaking hazardous materials Rupturing structural enclosures Experiencing thermal runaway or catching fire Disassembling or exploding Failure to present verified […]

How to Store Batteries Properly: Temperature, SoC, and Transportation Requirements Explained

Whether holding inventory in a warehouse or shipping products internationally, ambient storage conditions and State-of-Charge (SoC) are the defining factors in battery safety, performance, and longevity. For most battery chemistries, cool and dry conditions around 15°C (59°F) are recommended for long-term storage. Depending on battery chemistry and product specifications, allowable storage temperatures may range from […]

Custom Lithium-ion Battery Pack Design: Serie /Parallel Configurations Guide

Designing a custom battery pack requires balancing voltage, capacity, thermal safety, and cell consistency. Connecting battery cells in series increases overall terminal voltage, while parallel connections increase total amp-hour (Ah) capacity. Combining both in Series/Parallel (e.g., 4S2P) enables custom voltage and energy densities for medical devices, e-bikes, drones. Fundamentals of Battery Cell Configurations: Series vs. […]
