The 12v lithium battery is connected in series with 3 or 4 lithium batteries. The combined battery pack, the capacity of the battery is determined according to the capacity of a single cell or the capacity of the batteries connected in parallel, which is a new type of safe and environmentally friendly battery.
12V battery: Classified by material, it can be divided into: 12V lithium battery, 12V lead-acid battery, 12V nickel-hydrogen nickel-cadmium battery, 12V alkaline battery. 12 Lithium battery is a combination of three 3.7V lithium batteries in series. The voltage of a single lithium battery after fully charged is 4.2V, which is generally called 4V. The voltages of the series batteries are added together, namely: 4V/cell*3 A power = 12V, which is what we call a 12V lithium battery.
