My latest project has been modifying a battery box for the inevitable public safety power shutoffs this summer (and potential related emcomm use).
The box features a voltmeter with an integrated USB fast charger, a power switch to prevent inadvertent draining of the battery, and a 12-volt power socket.
The battery that I’m using is a 12-volt, 35 amp-hour AGM battery. There is extra space in the box to hold an inverter and spare parts.
Future improvements will include a panel-mounted quick-disconnect port to replace the one hanging out of the lid, and a 12-volt circuit ammeter to monitor my power usage.
This project was significantly more expensive to assemble myself than it would have been to purchase pre-built online; however, I was able to customize it and use higher-quality components from Powerwerx.
