I recommend getting a Noco GB40 (or similar), which has 1000A or larger jump pack for this instead of using your trolling motor lifepo4 batteries. I have had to jump my engine several times due to my group 31 not having enough juice to crank the engine.
I also recommend having a power switch isolating your graphs from the battery when jumping it to avoid damage to the graphs.
I run livescope, a garmin 93 at the bow, a garmin 106 at the console, dual power poles, and the livewell pumps on a single group 31 lead acid battery due to my engine requirements. I have on multiple times had my battery too low over 6 hrs of fishing to start my outboard. Thus, I am going to buy a "budget" lifepo4 battery for electronics only to get my graphs off the main battery to improve reliability and also allow for me to add another graph and livescope for full time forward and perspective modes.
