How to Select the Right 120Ah Lithium Battery for Your Needs
A 120Ah lithium battery provides an efficient and reliable energy storage solution, delivering up to 1,536 watt-hours of power, making it ideal for various applications such as RVs, marine use, and solar energy systems. Its lightweight design and long cycle life offer significant advantages over traditional lead-acid batteries, ensuring dependable performance for diverse energy needs.
What is a 120Ah Lithium Battery?
A 120Ah lithium battery is designed to deliver 120 ampere-hours at a nominal voltage of 12.8 volts, equating to approximately 1,536 watt-hours of stored energy. This capacity allows it to power devices such as lights, refrigerators, and electronics for extended periods. Most commonly, these batteries use lithium iron phosphate (LiFePO₄) chemistry, known for its safety and stability.
How does a 120Ah Lithium Battery work?
Lithium batteries function through electrochemical reactions between lithium ions and electrodes within the battery cells. During charging, lithium ions migrate from the positive electrode (cathode) to the negative electrode (anode), storing energy in the process. When discharging, this process reverses, allowing energy to flow back out to power connected devices.
