Welcome to the forum.

There are quite a few alternator related threads that are active at the moment. From measurements on a completely different car, the minimum the ecu and ignition needs is approx 6-10A. So your lithium will last about 10-20 minutes before it needs to be recharged, assuming it can deliver the necessary amps.

I’ sure others will chime in shortly.
