| I have read about people using a battery at the end of a long 12V wiring run to stop the voltage drop associated with DC wiring. I'm having a hard time understanding how this works. My assumption is that this would work for temporary loads where you turn the load on for a minute or two and then have it off for 5 or 10 minutes. However, if the load is continuously pulling 30 or 40 amps you're still going to have to have wire that can handle a 30 or 40 amp load for that distance because that battery is always going to be pulling 30 to 40 amps to keep it charged essentially...correct? Thanks.
