Has anyone moved from AGM to Lithium batteries? About to swap my 3x200ah AGM for 2x300ah LiFePO4 parallel, and want to be sure I'm understanding the upgrade and hear experiences...
I'm in a custom van, mostly charging with 700w solar + 100 | 50 Victron MPPT, a 30a Orion, and occasional grid charge from my 12 | 2000 MultiPlus. They're hooked to a VenusOS RPI (Cerbo) with a SmartShunt and temperature monitoring. All 3 charge devices have Lithium settings, and the batteries will have internal BMS. Am I missing another piece to this configuration - for lithium - like an external BMS or voltage disconnect?
Also, anyone who's done this upgrade, with the same AH capacity I know I can draw the batteries much lower, but has anyone experienced the differences in charging speeds? My AGM batteries spend most of their life in absorption, rarely accepting the full solar available even in bulk, unless I'm using my electric cooktop, which decimates my AGM's. Hoping this will change with Lithium.
Thanks for any advice or experience!
