Series or Paralell?

[arrowskartax9]

Hi Everyone, I have a MHZ Mystic 44 inch cat with twin Castle 1717's in it with 180amp hobby wing esc.
It is powered by 2 Hyperion 5s 18.5v 35c lipos.
My question is, Do i run these in paralell or in series?

Parallel. An easier way is to run one battery per motor. No need to run them together, which, if you did, it would be parallel NOT series.

Great, Thank you.
