Hey This is interesting.
Can you please detail out what all information can the unit you built for each battery give as an output.
There is an LED indicator to depict some info. what are those?
Not sure if information can be transmitted to an app to set alerts?
Also how to DC input is the device taking in?

Well timed @rsaeon article. I am building something similar for my DIY UPS. Yours is more robust than what I am planning to build. I do not have a working prototype yet, but the idea is to use an ESP32 board and use multiple ADC inputs on it to measure the battery voltages. That works because my UPS uses 7AH batteries which are placed next to each other.

Awesome! You just saved me some money that I can now use to buy battery for that module. Your posts have inspired me to share my build log. I may not be able to match quality of your logs, but I will definitely will give it a try. 
To avoid battery deterioration you can try using the Battery Desulfator devices.I have one fitted in my inverter battery. I was able to stretch life of my previous inverter battery to ~7.5 years. I have a spare that I can send to you for testing or you can order one from the supplier I recently bought more units. See if you are able to revive your old sulfated battery. Had it not been my ignorance towards checking water levels for the whole of pandemic, I could have had the battery still running. The battery was literally running on empty by the time I figured that it needed a top up. I had to pour ~12 litres of DM water to top it off.

Wow. Somewhere around 2018 we (me and a friend) had developed similar stuff for making normal UPS smart with the addition of 8266 and some other circuity. I will be deploying this next year. This was part of industry 4.0 equivalent at that time.

Thanks Mr.Rsaeon,As a newbie to this,i followed your steps for everything to build a one.But not showing anything on the homepage of tasmota.Cud u pls stepup and check?
