Powering 12 volt fence energizer from 24 volt battery
Hi, what would be the most efficient way to power a 12 volt electric fence energizer from a 24 volt battery? I have a fencer running to protect a bee hive and have to leave it unattended for a couple weeks at a time, I currently an leaving a small exeltech xp250 running with a battery tender 12v, 750mA charger to keep a regular sized car battery charged, which in turn powers the fencer. The fencer uses 500mA @ 12 volts.
I am thinking either a 24-12volt converter of some kind, or a small charge controller?? It would need to be able to input up to 30+ volts, but not much for amps. Thanks, HH
