I use the DVCC override feature on my Cerbo to effectively put my boat's battery into "Storage Mode." When I know I will not be using it, I'll use the DVCC functionality and "Limit managed battery charge voltage" to 13.2v and allow my battery to drift down to around 62% and stay there. Then, the day before I'm about to head out, I'll remote in and turn that off, letting the system fully charge the battery overnight.
The change in behaviour that I would love to see is that the default value for that DVCC voltage should be whatever voltage is being directed by the BMS. Right now, when I turn that feature on, it initially sets to 56.6v, which I then have to adjust down 0.1v at a time to get it to 13.2v. Additionally, that 56.6v would be dangerous/invalid on a 12v nominal system (or 24v nominal for that matter).
