I wish I could help you, but...
With a 2009, you should have the Danaher controller. I could not even begin where to tell you to go in and adjust the voltage settings to be compatible with the lithium pack voltages on the high and low ends. The lithium pack high at full charge is well above that for a lead/acid pack, and the lithium pack low at minimum acceptable charge is well below the low voltage cutoff for a lead/acid pack. The Curtis controller has these setpoints in the advanced parameters, not so sure about the Danaher controller. I'm using a Curtis controller.
I spent $5400 on lithium cells and $645 on the BMS. I'm building my LiFeMnPO4 pack for 200 Amp/Hrs.
