Key Ignition w/ Voltmeter Wiring

[pogihlang]

Hello guys, I been working on my dual motor conversion kit. I found out that I cannot do two controller in one LCD display. I need to plug each display to each controller so I can controller both motor. Now in my current setup for single motor I installed key ignition switch with voltmeter (See photo of the wiring with one controller) and it is working fine.

My question now is, the wiring I drew on one ignition for two controller is possible? ( See photo).

This is another wiring. Taking battery voltage on controller one then split it to the 2nd lcd display.

Is this possible?
