FAQs
What are the advantages of steel-shell 18650 cells compared to pouch cells?
Steel-shell 18650 cells have better dimensional consistency, making them more suitable for automated production. They also perform more stably under high-temperature and high-current discharge conditions, making them ideal for battery packs that require high consistency.
What are the common capacity configurations of 3S steel-shell 18650 battery packs?
A single 18650 cell typically has a capacity of 2000–3500mAh. When configured as a 3S multi-parallel pack, the total capacity can range from 2Ah to over 30Ah. For example: 3S1P (2200mAh–3500mAh), 3S4P (8Ah–14Ah), 3S8P (16Ah–28Ah). The configuration can be customized based on the device’s endurance requirements.
What are the typical application scenarios of 3S steel-shell 18650 battery packs?
They are mainly used in drones, industrial handheld terminals, medical instruments, electric toys, portable power supplies, outdoor lighting, and security monitoring equipment.
How does this type of battery pack ensure safety?
The battery pack is equipped with a built-in protection circuit (PCM/BMS), providing overcharge, over-discharge, overcurrent, short-circuit, and temperature protection. Additionally, the steel shell offers extra mechanical protection, reducing the risk of thermal runaway and external damage.
Can steel-shell 18650 battery packs replace lead-acid batteries?
In some 12V applications, they can replace 12V lead-acid batteries, offering lighter weight, higher energy density, and longer cycle life. However, device compatibility must be confirmed, especially regarding the voltage range (Li-ion: 9–12.6V, lead-acid: 10.5–13.5V).
How to choose the right supplier for steel-shell 18650 battery packs?
It is recommended to choose manufacturers with strict quality management systems (ISO9001/ISO13485), certified by UN38.3, IEC62133, UL, etc. The supplier should also be capable of providing cell consistency matching, reliable welding and packaging, and comprehensive customization services.
