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...

I didn't take current readings at the Renogy input when charge voltage approached 14.4v. Odds are the Renogy's input current starting going up slightly once the Renogy's output charge voltage exceeded the alternator's 14.1v output voltage.

otrfun got 13.8 x 42.2 = 582w in and 40 x ? 13.4 ? = 536 out = 92% . . .
