Solar panel extension wires
We just bought a solar panel to help extend our batteries when dry camping. The wires provided with the panel are very short. I would appreciate recommendations for where to find extensions of 20 to 3...

.2 volts drop with 10 amps would be a 2 watt loss in the extension wires which is insignificant. Also as the battery approaches full charge the current drops so the voltage drop steadily decreases.
I have the controller at the panel and it is set to AGM mode which produces a max voltage of 14.4V. Measured, it is producing 14.47V at the panel and 14.4V at the battery with a 40’ 8 AWG cable set and 5-6 amps.
most DVM are not fast enough to measure the ON/OFF of the CC in absorption. If ya switch a 5A load on and off 1/2 the time the current is still 5A when on and not 2.5A (current drop?). Less sun does = less current = less vd.
remote voltage and temp probe are available with some CCs
