    Yeah no, line voltage will kill you if you don’t know what you are doing, not to mention the fire hazard as was mentioned. The 12/24 volt used in computer systems much easier to mess around and not ‘find out’ other than maybe a fried component. Unless you are an electrician/ electrical engineer with proper training don’t open/mess with Power Supply Unit (PSU) or UPS.

    One mod anyone could do is swap their lead acid for a LiFePO4. You just need to make sure the same voltage,battery quantity (larger backups often have 2 batteries in a series) and the battery dimensions are the same. They should be drop in replacements and do last longer.

    That being said, I myself, do have training and if you want to waste your time I probably would mod some UPS with a car battery for longer down time support. Watched a YouTube video of a person do it to find the pitfalls for me and the issue is heat as it’s not expected to run off battery + inverter for longer than the smaller battery normally allows it maybe 5 minutes compared to like 1 hour, so several fans and heat sinks on critical components would be needed adding minor complexity and planning.





  • Yeah, I actually finally got rid of mine a year ago, but it never was allowed to access the Internet. Also didn’t support smbv3 when those huge issues came out so has to use custom package sources to get updates. Never buying something unless it can have open source firmware flashed any time for my NAS hardware. Using TrueNAS now on slightly old custom built PC I upgraded from.
