I had my kodiaq a couple of months ago and have been worried given what I’ve been reading about the 12v going flat. So far it hasn’t happened to me. Given my concerns I’ve tried to make sure that I connect the charger close to bedtime, maybe 2-3 hours max before the off peak rates kick in, and I disconnect it again first thing in the morning, which is usually about 3 hours after the end of the off peak charging period. The actual start and end time will vary though because I am on Octopus Intelligent go. Maybe my troubles are still ahead of me with regards to the battery going flat, but just wanted to share to give some confidence to others that they might not necessarily face the same problems that some have been facing.
