I have the following:
- Two 12 volt batteries hooked up in series to supply 24 volts to a
a 120 watt LED lightbar.
- One 12 volt battery that is hooked to a switch.
- A relay that has a max operating voltage of 27 VDC. (http://www.foocles.com/FLS821G-pd934013.html)
Can I safely supply the relay with 12 volts to "switch on" the 24 volt load to power the LED lightbar?
