New battery

Kentsb · May 2021

I am upgrading my battery on my 2021 320 CSS Boondock with factory solar. I am going from a group 24 SLA 81ah Interstate battery to a group 27 Universal Power Group 100 ah AGM. I have the Victron controller HQ1838NZ732/MPPT 75/10. Will I need to make any adjustments to the controller for this upgrade?

Adjust the battery capacity and if it has a selector for AGM, change that, too.

I have downloaded and read the manual, contacted the support community for Victron and while my suspicions have been confirmed, no one has offered any specifics. Could I really be the first person to do this? Any suggestions on where I could go to get answers?

@Kentsb - you asked specifically for what you need to change due to a new battery. You need to change battery capacity under Battery settings. There are other discussions here regarding full settings.
