Finished off the wiring on the Renogy DC-DC charger and did a bit of testing today. Everything is working as it should, all the LED’s are visible by looking under the front of the drivers seat which is a bonus. It should also be possible to change a fuse without needing to remove the drivers seat should that ever be required.
As part of the testing, I attached my fold up 50W solar panel just for the hell of it to see if it would charge even though there was no sun. It recognised it was there because the voltage output was over 15V but that is about all it did. It did prove the unit is doing what it should and turning solar on if the voltage threshold is reached. A bigger panel might have provided a little charge. I have a 180W panel waiting to go on the roof.
I also had a bit of a play with the Bluetooth app to see what it does. Functionality is limited although it does show the basics. There is another app which allows configuration of the charger which I’ll play with another time. Haven’t decided where I’m going to mount the Bluetooth module yet, there is so much cable on it i could put it anywhere in the van
I also managed to source a rubber cover which should fit the positive battery terminal properly. Just waiting for it to arrive so i can put that in place rather than using the yellow plastic thing which I’ve had to modify to make it fit (which it does badly). Fortunately not using the van just now so haven’t bothered to fit the drivers seat until i get that fitted.

Clamp holding battery in position. Battery tray is screwed to the seat base so battery is nice and secure. BM2 has been moved and fixed to top of battery since i took the picture.

The USB sockets I fitted in the B pillars. They have a touch controlled on/off button. I chose these so i could turn them off so there is no parasitic drain from them. They light up when they’re on. Not sure I’m going to leave the covers on them, will decide later.
