In my bassboat im thinking about putting a Phoenix 12/350 inverter to my startbattery and connect 2 stk Bluesmart Chargers 12V/7A to that inverter. I will only use the inverter when running the engine. The battery that each smart charger is connected to is Lithium 12/50Ah. Im running some distances between my fishingspots with the engine and was thinking that to charge the lithium batteries for the trolling engine in front. I already have the Phonix Converter and the Smart Chargers.
Or is there another charger 12/7 that can be connected to the start battery and used when i run the engine?
