Hi. I have plans to run a 400 foot electrical wire then put plugs on either end. I will be drawing about 1.5 amps at the end of the line to a 12 volt battery charger and then into a battery. I understand I will have voltage drop and from my calculations i can run a 16 gauge wire and only have about 7 volts of drop. Will this work for a battery charger and do you guys have any suggestions or ideas? I am going to be running a battery maintainer that goes into a deep cell battery that then goes into a shurflo 4008 pump. Has anyone done a similar setup?
