OK: Equally divided battery current.
All batteries contribute equally to the current into the load.
NOT OK: Current not equally divided.
Batteries closest to load will have the highest contribution to the current into the load.
Whereas batteries further away from load will have lesser current contribution.
Wear and tear will be higher on the battery close to the load.
