We also upgraded to lithium last summer (2024) on our 362 and have used them continuously since. We took a slightly different direction and installed two 330 Ah Victron batteries instead of three 200 Ah batteries. It is slightly more capacity for about $100 more, but the batteries fit in a smaller space (except for the height). A very small modification of the board that covers the battery compartment was necessary, but other than that, the larger batteries fit well in approximately?the same space as our two old AGM batteries.
