Need help with connecting 4 Lipo batteries

Hello everyone.

I’m about to start build my first electric skateboard. Currently I have 4 units of batteries, each one is 4s, 70c 1500mah. I Will use flipsky vesc 4.2 50a and 6374 140kv motor.

Can you please tell me how can I use them the best way?

How to connect properly? How to program on vesc tool? What numbers to apply when programming?

I really need your professional help with that, I am too busy flying to the moon at the moment.

Thank you all so much.
