My friend lives in Florida and I wanted to make her a remote lighting system and 12VDC power supply for power outages.
Tractor supply had 14” Flambeau dry boxes on sale for 50% off and I picked up two. I took one of the boxes to Batteries Plus and found that two 20 amp hour deep cycle batteries that fit in the box with room to add outlets and an integral charger.
The build was very simple. I wired the batteries in parallel, drilled for the outlets. I put in two cigarette lighter plugs and a dual USB plug. I found the switched voltmeter on Ebay and it fit perfectly inside the case.
I had an old Black and Decker 2 amp charger that fit perfectly inside the case. Rather than opening the case to plug in the charger I found the NOCO Genius GCP1 Black 13 Amp 125V AC Port Plug on Amazon.
Next up was lighting. I found a tripod for $18.00 and a 50 watt light for $10.00 on Amazon.
The power pack was able to power the LED light for 40 hours. Below is the supply list.
