How Many 18650 Batteries Do I Need For 12V?
In order to answer the question of “how many 18650 batteries do i need for 12v?” we need to understand a few basics about batteries and electrical circuits.
Batteries store energy in chemical form and release it through a process of electrolysis when a load is placed across the terminals. The voltage of a battery is a measure of the potential difference between the two terminals, and the current is the flow of electrons through the circuit.
The capacity of a battery is measured in amp hours (Ah), which is the amount of current that can be drawn from the battery for a given period of time. For example, a battery with a capacity of 1 Ah can provide 1 A of current for 1 hour, or 2 A for 30 minutes, etc.
The voltage of a battery is determined by the number of cells in the battery. A cell is a basic unit of a battery, and each cell has a voltage of around 1.2 V. A battery with two cells in series will have a voltage of 2.4 V, and a battery with four cells in series will have a voltage of 4.8 V.
Now that we understand the basics, we can answer the question of “how many 18650 batteries do i need for 12v?”
In order to create a 12 V battery, we will need to combine four packs of cells in series. Each pack of batteries will contain 20 18650 cells, for a total of 80 cells.
The capacity of the battery will be determined by the number of amp hours (Ah) of the cells. A cell with a capacity of 1 Ah can provide 1 A of current for 1 hour. Therefore, a battery with 80 cells with a capacity of 1 Ah will have a capacity of 80 Ah.
This means that the battery will be able to provide 80 A of current for 1 hour, or 40 A for 2 hours, etc.
Additionally, We can draw a schematic of the system with all the information we have. To create the 650Wh battery, we will combine four packs of cells in series to create a 12-16.4V battery voltage. Each pack of batteries will contain 20 18650 cells to give a capacity of 55Ah. This means we will use 80 cells in total.
