Aws lamda /aws batch

I have a linux binary takes test input files one at a time (1.pdbqt, 2.pdbqt, etc) to processes to generate output files. I deployed the attached zip to lambda and can successfully run on AWS (128mb/5min timeout).

I need an AWS batch/lambda setup to process 100,000 input files residing in a S3 bucket and write outputs to another bucket.
