So ask what are your specific questions, and i will try to help you here. Also provide all necessary details about lithium battery packI get what your saying, but, I'm looking for the most probable value the car might sense for;
IR..? , well thats a moving target depending on temp, capacity and SOC. so, i doubt its that.
AGMs have a low IR anyway, very similar to lithium.
Current flow, well i dont see how a diff current would come out of the batteries.
If the car wants 10Amps, it will get 10 amps.
Temp; I dont see any difference, we're not talking about any heavy hi rate discharges.
ALthough the charging profile is different, the lithium can accept a lead profile even though it may not be fully charged at the end.
VOltage, is the only thing i can see... ie, voltage drop compared to the current draw. the Li would be less, although, that also depends on the Ah of the battery.
I'm still stumped. We dont know the answer. Maybe i should contact the eng dept at Kia. to find out. if thats humanly possible
Does it have dedicated BMS, heater, and anything else that is not similar to the factory 12V battery.
