Distance to 50A power?

[garysfb]

OK I must have slept through my basic electricity classes in school. Is there any difference in a heavy duty extension cord and running a buried line 100 feet from my home's pool equipment breaker panel, and the electric post at the RV? Or would the drop in voltage be the same?

Distance and wire size and amperage of the circuit determine voltage drop.

….distance, total amps and wire gauge have to be considered....lots of apps on the internet will do the calculation for you--just plug in the numbers.....OPs question was limited to powering fridge and bat charger [assume he is floating the bats], he wont need much of an extension...minimum of 12 gauge, 10 gauge would be nice, 50 amp cord [6-gauge] will handle about all you can draw...just remember, the calculation begins with your input voltage, so if your house is already low, like 110v, then 5% of 110v is a smaller/less acceptable number.....NLT 5% voltage drop seems to be an industry goal…...
