Pro 170 Battery question

[Zpilot]

I am going to add a Ghost 24 volt trolling motor in place of the 12 volt MinnKota currently on the boat. I am looking for ideas from those who have done something similar where to add or move both batteries for the 24 volt motor? I am also thinking perhaps a lithium single 24 volt battery might be my best option. Appreciate any ideas you folks might have.

I got rid of my 2 12v last year, replaced with a 24v, plenty of room and saved about 50lbs, plenty of battery life left after using 6-7 hours...
