Lithium battery as starter assist
I am considering changing out the house batteries with a single 100 ah lithium. In certain conditions I need to use the battery combiner dash switch to start the engine. Would this still be possible...

. . . The battery management systems on Li batteries limit the output to about 100 amps (some are more some are less). The starter draws hundreds of amps . . .
