Wasn’t finding an affordable UPS power supply with the features I was looking for so decided to make my own.

All in all about half the price of the common ones you see on the market with the same features.

Main goal was to last at lease 10hrs runtime. To get there it cuts the available current so the pumps run at about 30%.

All the safety features like over-under charge protection, etc.

Still working on the enclosure a bit but getting to something I like.
