The popular thing is to run a 4th battery for Livescope and most are going with Lithium set ups, but I'm not sold on the value of Lithium set ups yet, when you add up the cost of a Lithium charger, 100amp/hr Lithium battery and the hassle of plugging in another charger and finding a place top mount the battery, it just doesn't make sense. I was quoted over $1100 to change over and from what I read Lithium's have a 11yr life expectancy where as a Lead 100amp costs me $140 and should last 3 to 5 yrs, plus what no one mentions is that you cant safely jump a lithium if it goes down. Maybe Im old school but for now im sticking with a 3 lead battery set up.
