Hello.Can anyone help me with a circuit diagram of an active equalizer with 4 12v batteries(48v total )? The batteries should be connected in series and arduino should show the voltage of batteries.

An image search for "battery charge balancer schematic" will turn up lots of circuit examples.

Here is one for LiPo batteries, easily adapted to other voltages:

So not lead-acid batteries, because they don't need that.

Voltage can be done with four voltage dividers.
How depends on which Arduino (you didn't tell).
