I was going to build a ups for my server rack but after calculating how many batteries I would need to buy, I decided that would be a longer term project but then it downed on me to ups back my chest freezer. I have a go bit of experience with batteries form a hobby club in college but I have next to 0 experience with inverters. I current plan is this:
Batteries: 4 x 3.2V Lifepo4 100 Ah
BMS: 4s Overkill BMS (making sure it does balance the batteries correct?)
Charger: 12V 20 Amp Lifepo4 charger (https://www.amazon.com/gp/product/B...02b6cb41&language=en_US&ref_=as_li_ss_tl&th=1)
Inverter: ????
I would love to use the one from the milk crate vid (https://www.amazon.com/Inverter-600...ea257711&language=en_US&ref_=as_li_ss_tl&th=1)
but I don't like I have to turn it on manually as I want it to be a ups. I was also looking at hybrid systems but they seam overkill/too expensive for this application and what I can afford atm. This is the best one I found so far (https://www.amazon.com/POTEK-Invert...ords=automatic+inverter&qid=1622692133&sr=8-2) but I felt best to ask others on there option. I would love a inverter/charger combo for but to find pure sin wave inverter with transfer switch and lifepo4 charger for "cheap but good quality" I looks like I have to buy them separately. All the help is apricated.
