I have a customer that has a 48v bank consisting of 2 x Victron 25,6V/200Ah Smartbatteries.
This is for a 2kW marine propulsion system. The batteries have been in use for the last 1.5 years.
There is a Quattro 48/3000/35-50/50 120V for dosckside charging as needed and what will be 1700 watts of solar.
The owner needs to extend the range and ability to travel overnight and intends to add two more 25,6V/200Ah Smartbatteries for a 48V x 400ah bank.
How can we best integrate the new batteries into the system and still have a reliable system that does not cause the BMS to fault due to cell imbalance? i.e spend more frequent time at absorption voltages to balance cells with different internal resistance?
