Hi All, Regarding the Renogy 20A DC to DC Battery Charger 12V, the unit puts out 20 amps, but draws 30 amps when doing so. This is the result of bench testing.

BFL13,
#8 has a voltage drop of 2.46% at 10 feet (more than I need). It can carry 55 amps.
The whole idea of the dc to DC is to boost the voltage going into the battery bank. Therefore voltage drop to the charger doesn't matter--so long as the ampacity of the wire size is not exceeded.
On the Output side I might have about a 4 foot run. Voltage drop about 0.76% with #8 wire at 20 amps. Pretty much I think that can be ignored.
I must look up the charging voltage on the telcom jars that have served me so very well.
Thanks for the thought provoking comments.
