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...

Notes from back in Feb on 7-pin vs DC-DC:
7-pin starting at 13.2 amps and after a minute was 10 amps and after four minutes was 4.4 amps.
Renogy does its 20 amps in Bulk tapers only in Absorption.
I got the thing as an emergency battery charger for the TC which has no generator, that DW can operate if I am not there, if the camper batts get too low and no sunshine. (Turn on truck and let it idle, turn on Renogy switch in camper)
Also I did not want to mix the house and engine batteries in parallel with their different chemistries (but Mex et al say that is not a real problem)
Probably never get used, but it beats getting somebody else at a dog event to help out with jumper cables like you see some people needing at times. (Some folks are good at dog stuff, but shaky on how their RV's work)
Renogy will add its amps with solar amps with the same Vabs settings too. You can't set a 7-pin Vabs so you lose some " alternator charging" with the solar on with its higher voltage.
I don't need it for the Class C in our scenarios, but if I did, I think it could be swapped back and forth using quick connects. For the price, probably just get another one for the C.
