Topic: Size of ground wire munit to battery

[toadm]

Hi. I have a 76CB750F with munit blue, ricks regulator rectifier and Shorai lithium battery. My munit GND connection is connected to the engine ground wire via a 6 AWG cable. I understand I should/could have an additional ground wire connection from munit GND connection direct to the battery, and use a 14 or 16 AWG wire. Is this correct? Can I use a second, direct GND connection using 14 or 16 AWG wire from battery to GND on munit?

Thanks in advance

Yes. 10-12AWG would be better.

Thanks so much!
