How To Hook Up A 24 Volt. I cant quite wrap my head around how to wire 4 12volt batteries together to make a 24 volt system but I found this wiring diagram online and want to see if anyone for sure knows if this is correct. 24 Volt Systems 2 batteries.

That is overkill for a radio but good for extra accessories too. Connect a connector cable to. Wire in series only as directed in wiring diagram to provide 24 volts.
Any help would be appreciated.
Typically this setup will include two 12 volt batteries. Once the charge is delivered the voltage returns to 12. 2 wires to your 24 volt batteries and 2 wires 12 volts output to your accessories. Basically there are 3 separate electrical systems within the one main system.
