All it takes is a whole ton of ingenuity!
Awhile back I built a little 16AH 200wh
battery box. LiFePO4 cells in 4S2P config. I charge the box by plugging it directly into my 100AH LiFePO4
battery in the
scamp.
I own a pretty old 300W AC inverter, modified sin wave!!! But it works to plug in my two lap tops. By itself it ran my laptops for about an hour. When its voltage dropped so low the little inverter dropped out I had to get clever. I took the
battery box out to the front of the RV (19' Scamp), plugged it onto my LiFePO4 battery, plugged the inverter into the battery box, then a 25' extension cord into the inverter, ran it into the door of the
Scamp.
Voila, raggedy a$$ modified sin wave delivered to the laptops back at the table in the
Scamp. Wifi hotspot through my phone.
High tech man!
