FAQs
What is the difference between a lithium-ion battery pack and a single cell?
A battery pack is composed of multiple single cells connected in series or parallel, and integrated with protection circuits and a Battery Management System (BMS). Compared with a single cell, a battery pack can be customized to achieve different voltage and capacity requirements.
What is the typical cycle life of a lithium-ion battery pack?
Depending on the design and usage conditions, consumer-grade lithium-ion battery packs usually have a cycle life of 300–500 cycles, while high-quality packs can exceed 500 cycles.
Do lithium-ion battery packs have a memory effect?
No. Unlike Ni-Cd or Ni-MH batteries, lithium-ion batteries do not suffer from significant memory effect. Users do not need to fully charge and discharge frequently; charging as needed is sufficient and does not significantly affect the lifespan.
What role does the Battery Management System (BMS) play in a battery pack?
The BMS monitors the pack’s voltage, current, and temperature in real time, providing protection against overcharge, over-discharge, overcurrent, short-circuit, and overheating. It also performs cell balancing to ensure consistent voltage among cells, enhancing both safety and lifespan.
How can I choose the right lithium-ion battery pack?
You need to consider factors such as voltage, capacity, discharge rate, size, weight, safety, and certification requirements of your application. For example: drones require high-rate battery packs, medical devices prioritize stability and safety certifications, while energy storage systems focus on long cycle life.
What are the most important factors when choosing a battery pack supplier?
Key factors include: whether the supplier has a complete quality management system (such as ISO9001), certifications like UN38.3, IEC62133, and UL, comprehensive testing and after-sales support, and strong R&D capabilities to meet customization needs.
