1. What is a 12V Lithium Battery? A 12V lithium battery is a battery pack composed of 3 or 4 lithium cells connected in series. Each cell's capacity and voltage can be customized to meet specific requirements, offering high safety and environmental friendliness. A common 12V lithium battery mod

Low-temperature lithium batteries can be categorized into high-temperature, low-temperature, and wide-temperature types based on their operating temperature range. Common cylindrical models include 18500, 18650, 21700, 26650, 26700, and 32700, while polymer models are even more diverse. Low-tempera
