Charge 48V battery bank with 12V


I have a 48V battery bank made up of 4 deep cycle 12V batteries in series. My charger only has 12V and 24V options.


I've considered using relays to put the batteries in parallel and charging at 12V. I'm assuming there has to be a better way. Ideally, one that allows all 4 batteries to remain in series.


Is there a common method to do this? What effect would charging one 12V battery have on the other three in series?
