Renogy DC-DC Charger UPDATE 2 Test
Update--fixed the problem below--you can skip to 4:06 pm post. Update 2- 28 Feb. My 20 amper is on, it has the green light and no red light. But it is cycling up and down for amps constantly, mak...

Not sure about the wiring of the Renogy but would assume it is similar to my Victron 12-12 Orion-Tr 30amp. The "-" connection to the source and load are isolated on the device, however can be connected together and do get connected together when the source and load share a common "-" ground.
Question for you guys
Anyone find a way to adjust the output/load current of a DC-DC converter?
Temporarily lowering the charge voltage does the job but is not as "clean" as desired.
The Bluetooth app does not offer any current adjustment that I can find only a custom voltage charge profile.
I charge a 200amp LiFe four cell prismatic home brew battery which will easily take the full 30amp from the DC-DC charger thus consuming 40+ amps from the source. My desire is to throttle back the charge current at times when the solar is not doing enough to keep up. The solar charges a 200amp PB battery bank. Don't care if it takes longer to charge the Li. I do not want to see my Pb bank get discharged while charging the Li bank. Yes I understand I could set the source cut off voltage high enough to eliminate the possibility of too much discharge but again it is not a "clean" solution and would cause the cycling on/off issue.
