Welcome back Roger. For 12v 100 amp hour Lithium batteries, you should use 2 AWG wiring. This will prevent voltage drop and overheating. Other than the correct gauge the other important thing is to use the same length when connecting them to balance the charge and discharge load evenly across both your Lithium batteries.
We've got a few different lengths that will work with your batteries that I have listed below. They all fit 3/8" terminals. You'll want to go with the shortest length that will connect your batteries.
Red - Battery Cable Harness Assembly - 3/8" Stud - 7" Long item # DW04317 and Black item # DW04318
Red - Stackable Battery Cable - 3/8" Stud or Bolt - 7" Long item # DW01484 and Black item # DW04315
Red - Stackable Battery Cable -3/8" Stud or Bolt - 13" Long item # DW01485 and Black item # DW04316
