Lithium Upgrade.

Blue Grand Driver. · Sunday at 9:37 AM

Hi, recently upgraded to lithium in our 2021 680. Realise there are a heap of posts on this, but thought I would share our process, as pretty straight forward and very happy with outcome, so far. We fitted a Redarc Alpha 150 battery which has exactly the same dimensions and polarity and posts as the OEM AGM. So straight swap in out. Swapped the split charge relay for a Victron DC-DC, flipped the slider on the Solar panel MPPT in the back cupboard and that’s it. One tip while the battery is out, mount the Victron on the plastic upstand directly behind the battery, as there is plenty of room there. The redarc, and the Victron, apps on your phone for status and any adjustments. The GC control panel reads volts and amps correctly as well. 3 x power available and certainly removes the battery angst we had with the AGM.

Good advice, one point to remember is that the Victron should be mounted on a "Non Flammable verticle surface" as per the instructions. Monitor the battery temperature, it will more likely get too hot.
