Therefore, the lithium battery must also be about 58v, so it must be 14 strings to 58.8v, 14 times 4.2, and the iron-lithium full charge is about 3.4v, it must be four strings of 12v, 48v must be 16 strings, and so on, 60v There must be 20 strings in parallel with the same model and the same capacity.
Two 10ah batteries in parallel are 20ah, 48v ternary lithium must be 14+14 10ah batteries, and finally 14 parallel connected in series to form a 48v20ah lithium battery. Calculation method two: In fact, it is very simple. For example, 48 volts usually refers to voltage.
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
The whole set of batteries is 14 strings multiplied by 10 cells = 140 cells. Summary: Series and parallel have their own advantages for lithium iron phosphate batteries. Series and parallel lithium battery packs have different methods and achieve different goals.
In the lithium battery pack, multiple lithium batteries are connected in series to obtain the required operating voltage. If what is needed is higher capacity and higher current, then lithium batteries should be connected in parallel.
A 7S battery made from 18650 cells will have a voltage of around 24-volts which you can reduce down to 12-volts. This means that in addition to powering a 12V buck converter, you can also power a host of 24-volt devices like inverters, fans, pumps, motors, etc. Easy to use 24v to 12v buck converter.
