Lithium-ion vs. LiFePO4 Batteries: Core Characteristics and a Practical Selection Guide

In today’s battery technology landscape, lithium-ion batteries (NMC/NCA) and lithium iron phosphate (LiFePO4 or LFP) batteries are the two dominant chemistries. Together, they power the global transition to clean energy—supporting applications ranging from electric vehicles and consumer electronics to home energy storage and telecom backup systems. Although both belong to the lithium family, their chemical structures lead to […]

A Practical Comparison of Lithium-ion, LiFePO₄, NiMH, and Lead-acid Batteries

When people talk about batteries, the conversation often starts with numbers — energy density, cycle life, cost per watt-hour. In practice, however, battery selection is rarely that simple. Different battery chemistries behave very differently once they are placed into real products, operating in real environments, with real users. What looks good on a datasheet does […]

The Battery BMS Design with Dual Circuits

A dual-circuit BMS (Battery Management System) refers to a battery management system that utilizes two separate, independent circuits to manage and protect a battery pack. These circuits are typically designed to handle battery monitoring, protection, charging, and discharging etc., with dual circuit enhance the overall performance, safety, and reliability of the system.   Key Characteristics of a […]

Why LiPo Batteries Need Extra Space and Why Swelling Is Dangerous

Lithium Polymer (LiPo) batteries are widely used because they are light and powerful. However, many people ask: Why can’t a LiPo battery be made exactly the same size as the battery case? The answer is safety.   Why LiPo Batteries Cannot Fit Tightly in the Case   LiPo batteries need extra space to “breathe.” During […]

Fire Resistance of Lithium Batteries

The fire resistance and flame retardancy design of lithium battery is an important aspect of ensuring battery safety during use and storage. The electrolyte and other chemicals inside lithium batteries are prone to ignition, especially under conditions such as overcharging, short-circuiting, or impact.   Causes of Fire or Explosion:   Overcharging: When a battery is overcharged, […]

Swollen LiPo Battery: Causes, Risks, and Safe Solutions

Lithium Polymer (LiPo) batteries are widely used in smartphones, drones, RC vehicles, and home backup power supplies due to their high energy density and lightweight design. However, swollen LiPo batteries can pose serious safety risks, including fire, explosion, or device damage. Understanding why batteries swell, how to identify the signs, and the safest ways to […]
