there are lots of these available. seem too good to be true
Some have 12V, 9V, 5V + USB. Some include inverters. drop your 12v battery in & get going.
Smart Battery box
looks pretty good to use surplus batteries as usb chargers etc. some even support lifepo4
for indoor use, do they need to...
It's a 24' but very spacious. Not sure what brand of monitor + charger, will have it checked.
Looks like the following could be done based on above advice:
-MRBF - inline to DC devices
-Secure battery
-Close lid, attach battery terminals to inside of batt. box
-Buss bars to + and - of battery...
Inspecting battery box on a friend's newly purchased boat:
Looks messy. Any reason why the PV inputs of the battery box would be filled, but all devices are connected directly to + and -? No DC bus?
-Can't find bus bar - should this be bonded? Should it be re-wired so devices are fused...
