Renogy DC-DC Test Results-UPDATE 4 (Better!)
Updates 23 June--new test with Renogy input exposed for voltage readings Update 25 June more readings Update 4 - 27 June-- fewer amps with fat wire were noted this time! ----- I have the 20 ampe...

It sounds like the Renogy is current limited on the input to 30A. So it will pull 30A * However many volts it can, then convert that (with some inefficiency) to the output power. You most likely had enough voltage drop in the remaining wire that the limiting factor in all cases was the input current limit - thus it could never get to the full 20A on the output.
To make this test meaningful you actually need to measure the voltage at the input terminals to the DC-DC converter.
