Not sure about the batteries. I don't think 144v and 12Ah will get you very far. Even the other way round 12v and 144Ah doesn't look any better.
I think maybe you should be looking at 12v cells with 60Ah or more per cell.
Assuming your Suzuki weighs 1400kg (and assuming lots of other things)
At 30mph you will require 7854W of power to push it along a flat level asphalt road on easy rolling tyres.
That gives you 262 Wh/mile
Your batteries have 1728Wh capacity and only 1382Wh at 80%DoD
That gives you a range of 5 miles at 80%DoD or 7 miles if you completely flatten your batteries.
If you used 12 x 60Ah batteries at 12 volts each you will have 6912Wh capacity at 80%DoD and a range of 26 miles.
