voltage in a string of batteries and the adjacent strings of batteries are high? The battery voltage is normal.
Test which is to reduce
The even and odd batteries will not be balanced at the same time, which is to reduce heat generation.
Test protection board only equalize the batteries on one side?
enables even and odd battery equalization. The even and odd batteries will not be balanced at the same time, which is to reduce heat generation.
Why does the protection board only equalize the batteries on one side?
The protection board enables even and odd battery equalization. The even and odd batteries will not be balanced at the same time, which is to reduce heat generation.
