I want to use LifePo4 batteries in parallel.
I will use a Chinese model which are able to "talk" to VE.Can bus. I think they are using the Pyontech protocol.
Suppose I will use 5 batteries with 48V and 230Ah and the BMS can handle 200A charge and discharge.
So the question is: What is the maximum Amperage I can charge and discharge with 5 batteries in parallel?
Kirchhoffs law says that the current is reduced in a parallel circuit:
As all batteries will be parallel, theoretical I could use 5x200A = 1000A, but in reality its too much, isn't it?
One company gave me a formula:
n...number of batteries
n x 200A / 2 = Max A
This would be 5 x 200 / 2 = 500A
What is the experience of the community?
I am happy with any answer!
