SMA Sunny Island 6048 and Lifepo4 batteries (open loop)

Best solution is to get a compatible BMS and use the SI in lithium mode and retro fit that to the cells in your battery. You can adjust the VRLA settings for SOC disconnect etc to match the actual performance of your battery, just make sure the battery will disconnect from the Sunny Island if a cell goes out if voltage range.

Audi a6 2019 alternator 48v mild hybrid

Correct that battery is not cheap and its also made in Korea lmfao. I have a bare battery stripped down to the bare minimum just the battery itself with bms removed and so on. Even though the scanner said battery voltage was low roughly 10v after bms was removed I found that the battery still has 40v present. So based on what I found the BMS calls the shots.

BMS for Sunny Island 6048

I have 10 "cheap" BMS''s on my 132kWh bank. All but 16 out of 160 "Grade A" cells will not remain in balance above 3.5V/cell. The JK BMS does a great job on its 16 cells all the way to 3.65V/cell. I don''t use the BMS''s for control anyway, and I wanted redundancy, which is why I have several brands.
