After a long term usage of my solution I found out that there are a few reasons why usage of UPS is most effecient. One of the reasons is that for example with APC UPS you can use USB serial cable connected to Raspberry Pi and UPS and detect status of voltage, status of battery and status of UPS - '''This is a huge benefit'''. 50 minutes maximum of UPS is valid also only for cheaper models, for example this is not a case in Smart-UPS models which you can buy for few dollars used on second hand market with cheap replacement battery (but be advised that serial RS232 cables for APC ups are special and more expansive than regular ones). Also there is a main advantage of classic UPS and it is that classic UPS is fully working product which you do not need to make neither maintain. It can be a fun to make your own UPS on the first time but after a few years when you need to change something it can be challenging to maintain it long-term. | |||
