To get the most efficent charging to my batteries, with cost kept in mind, what wire gauge should I use between the batteries and charger?
I have a pair of 6v gc batteries.
They're about 12-15 feet from the charger.
I have a Boondocker 75A charger.
Currently have 6awg wire with very good crimped battery lugs.
Thanks
Crunching the numbers 14.6 volts 75 amps 14 foot (28 total using 6awg) shows a voltage drop of 5.68% (.83 volts) adding a 4awg to the 6awg would a bit larger then 2/0 awg and a voltage drop of 1.10% (.16).
It would likely be cheaper and more effective to move the converter. Can you?
