2010 Skeeter ZX225. I have two graphs and want to add active sonar along with a Ghost TM. I have wet cell batteries and want to upgrade to lithum. I was told to add three 50 amp and one 125 amp the 125 for cranking on all other needs. I have two power poles. Does this sound right? Hate to buy and then find out it am lacking. I am not a big tourny fisherman but will fish a few. Looking at Ionic. Will add the TM and Garmin down the road. Thanks
