Aquarium Battery Backup Box
prusaprinters
Connects a battery backup via relay. In my case I'm using a battery automatic switch module (https://www.amazon.com/gp/product/B07V5XYCGZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) and a 12v step up converter to 24v (https://www.amazon.com/gp/product/B01EFUHFW6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1). Cables use standard 5.5 x 2.1 mm DC barrel jacks. Wire the battery input into the DC converter, which is then wired into the Open side (IN 2) of the relay board. The closed side (IN 1) is for the standard power adapter. The OUT then connects to the device being powered. Make sure it works by unplugging the power adapter.Maybe one day I'll finish designing the cover… :)
