Why is it that large batteries are nothing more than many small batteries connected? Why not just have 1 single, large battery?
In: Technology
Batteries can only put out a set voltage (usually 1.1, 1.2, 3, etc) per cell and that voltage isn’t very high. And batteries only have a certain capacity (usually rates in load vs time milliamp hours or something to that effect)
To get to the voltage you want you put cells in series, so their voltage is added.
To get a longer life of battery at the same voltage you put cells in parallel so they share load.
