What is the difference between 24V and 48V lithium batteries?
2 Answers
48V refers to 4 batteries, while 24V refers to 2 batteries. Currently, one battery is generally 12V, so the difference between 24V and 48V lithium batteries is the number of batteries, 2 versus 4. Related introduction: 1. Overview: A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The inventor of the lithium battery is Edison. 2. Expansion: The chemical properties of lithium metal are very reactive, making the processing, storage, and use of lithium metal require very high environmental conditions.
I frequently work with battery applications, where the core differences between 24V and 48V lithium batteries lie in voltage and application scenarios. 24V batteries, with lower voltage, are commonly used in UPS backup power supplies or small electric tools like lawn mowers, offering affordability and easy installation. Doubling the voltage to 48V provides higher power, making it suitable for equipment requiring strong performance, such as e-bikes or golf carts. It reduces current loss by approximately 20% at the same power level, improving efficiency with faster acceleration and more stable range. However, 48V systems come with higher design and maintenance costs, requiring professional controllers to mitigate overheating risks. In solar energy storage systems, 48V has become mainstream as it directly matches inverters, simplifying the conversion process and minimizing energy waste. For budget-constrained or simpler projects, I start with 24V; otherwise, 48V is a worthwhile long-term investment.
