I am more or less full time in my van, have a 110ltr Waeco compressor fridge, MacBook, iPad, iPhone, Apple Watch, Amazon echo dot, 4G wireless router and other bits and pieces of electric gadgets along with a 12v Sharp smart tv and Firestick. I changed to
Lifepo4 18 months ago (2 x 100ah) and haven’t looked back. I also have an Eberspacher DT4 diesel heater using electric.
Whatever
battery’s you go for you need to be able to get them charged and keep them charge. I have 300W
solar on the roof and if you are anywhere like I am you will know the last 4 days have been mainly overcast and often raining, checking my
bmv my
battery’s SOC is currently 91% full.
if I need it I carry a 1Kw Hyundai
inverter generator which I connect to my hookup point to run 2 x 30amp
Victron chargers. I also have a 30amp b2b for when I move them van.
Don’t know if that helps or not
edit: I have a 300W
inverter I charge my MacBook with and the Karcher window vac and anything else I don’t have 12v plugs for, it uses almost nothing
