Dual DC Motor Speed Controllers Possible?
 

We are high voltage AC current people, new to the DC set-ups with speed controllers. We were making some drawings and something popped up. Is it possible to use 2 motor controllers instead of 1? For example, instead of using a 144v controller, can there be two 72v controllers connected to two separate battery banks in series? Just a thought, and what better place to ask the question.

It won't work. No need to either since one large controller would be cheaper.
