The easiest to use dual-battery system imaginable. Built in and around the Front Runner Wolf Pack box, these hand-wired units by GTFO make setting up your dual battery system easy as can be.
When you look at the auxiliary battery systems on the market now, you see a lot you don't need. Like multiple 110v A/C plugs. Why in the heck do you need like 3 of those, when everything for the camping world is designed around 12v D/C? It makes no sense. 

In the Battery Box Pro, you get numerous cigarette lighter ports, and numerous USB ports. So things like phones, lights, fans, etc. are all able to be plugged in at the same time. 
Plus, with the Victron Solar Controller, you have bluetooth access to all of your data, like daily power usage, real-time power draw, solar voltage and wattage input, and historical data that allows you to monitor the health of your battery.
