@BoxerProject that analogy is actually spot on 😄 Worth adding — are you monitoring voltage at the battery terminals rather than at the charger output?

@GafferTapeKing19 is right about the relay, but worth noting the contacts are rated pretty low — 4A max if I remember correctly.

Been there with mine on the boat. Worth checking if you've got the temperature sensor actually making proper contact with the battery itself—mine was just loosely taped on and drifting away from...

Had the same worries when I first mounted mine on the boat. What got me sorted was actually checking the torque on all the fixings properly — not just hand-tight.

The DCC50S is genuinely solid kit — I've got one sat on the shelf in the boat actually, pulled it when I switched to Victron too.
