Finally finished a little project I've been working on, a portable battery box. Originally inspired by
@JJBiggs who has something kinda similar, I went a little overboard. First I picked up an Apache 4800 box from Harbor Freight. This is a fantastic box, very rugged, with plenty of room inside for everything I needed. Then I added a FuelZero 50Ah LiFePO4 battery and a
Redarc BCDC1225D for control. It's got truck-input, solar input, a 12v port, 6 USB ports (yes that's silly), 30A inverter, two volt meters, and later I'll add a 30A output for external things like tent power. And if I count the FuelZero itself, there are two more USB ports and a battery condition meter. Took a long time and a lot of head scratching to get to this point, and I sure learned a lot.
The breakers in the middle allow me to switch off both input and output so the box can be completely powered down whenever needed. Blue Sea MIDI fuse on the power input and a Blue Sea 6-circuit fuse box to distribute the output power, only using 3 circuits right now. There's also a separate 30A breaker on the outside for the truck input, so the box can be isolated quickly, and nothing bad should get back to the truck.
Interesting the two outside meters show different values, but hey I'll always know what my power level is. The one above the inverter is the one I'll see from the back of the truck when we're camping. The other one will be forward-facing and the refrigerator will plug into that 12v port. Should be safe from accidental disconnects that way, which is something we learned the hard way last year. My son is a type-1 diabetic and when he goes with me, we keep his insulin in the fridge. My old setup had the 12v port facing sideways and it was real easy to accidently knock it out and then the fridge was off.
We'll give it the first real run on the SAS4 trip....4 weeks!
