The battery presets are completely out of date and with the latest firmware update. The maximum voltage setting only supports LiFePO4, not LiIon like Lithium Cobalt Oxide cells. I love Victron products, but in this case Renogy makes a much better product that works with both batteries (starter and home), smart alternator detection, and an MPPT solar charge controller for less than $200. I'm sure Victron will eventually catch up. Meanwhile, Renogy has the best product!
