I have a Powerhouse Lithium 100AH 16V dedicated to the graphs. I run 2 HDS Live 12s 1 Carbon 12, and a AT module/ducer. With the run & gun charger if you do a decent amount of running the 100AH would be overkill. I fish a small lake with almost no big motor time quite a bit and after 6-hours of use I'm normally around 80%. https://powerhouselithium.com/
