[QUOTE="condor22, post: 616936, member: 1932"] NJ - Here's some links to calculators/conversion Voltage Drop [url]https://www.rapidtables.com/calc/wire/voltage-drop-calculator.html[/url] AWG to mm sq [url]https://www.multicable.com/resources/reference-data/cross-reference-awg-to-mm2/[/url] Using 10 amps as the load (temporary) 10 or 12 AWG will be fine in most scenarios so calculate the drop for both. Keep in mind that voltage drop in a DC battery system is 2 fold. 1. The wire gauge will have a drop due to wire resistance over length, with a constant voltage source i.e. power supply. An AGM deep cycle battery is not a constant source, (next point). 2. Be aware you will see a bigger drop on battery volts depending on battery type, size and condition. My AGM dropped around 0.5 volts when the Glo Pin was on, then when the load dropped as it turned off the fan 1-2 amps only caused a 0.1/0.2 drop and the battery volts recovered. (Battery full and in good condition.) The more combined load, i.e. TV, lights and heater etc, the more an AGM voltage will drop. Lithium does drop, but not as much as an AGM, only around 0.2 volts at 10 amps, now I have a LiFePo4. [/QUOTE]
