I can’t quite make it out....I was charging my phone on the leisure battery, hence the 10w 0.7A draw. But, yes the battery should reflect the starter voltage as its before the CTEK. I need to investigate that I've connected the right cable. The MPPT is under the passenger seat and the battery the drivers, so quite a few cables going through the seat interlinks.

But it looks like you’ve got 2 cables connected to output,and only 1 cable to A terminal input on the Ctek?...
