Holy cow do I need (at least) one of these. For all the time I’ve spent nerding out on battery testers I’m legitimately amazed that I didn’t know about them. In the cart it goes:)

[@dancerehab1092]

I wonder if this would be ideal for use with an inverter backup system. Just for monitoring SoC so that I don't deplete the battery past 50%.

I got mine a week ago from Amazon but it came in a tiny cardboard box and very small instructions. But it's the exact same thing. I just hooked it up. My battery is dead dead so I also have a charger hooked up to it but I can't get this monitor to work. I bought a new Optima battery last month and it died really fast.

I have bought the same BM2 . Maybe you have investigated if these don't drain battery by themselves? It's rated 1,5 mA so about 0,02 W power, but you better never trust Chineese products without testing. For example yesterday I have checked my brand new Bosch battery and all voltmeters (all made in chine) showed completely different results: 12,50V / 12,58V / 12,10V / 12.54V ...

I've got two of these connected to 12v lithium batteries (diff brands)....my app picks up both batteries as lead acid and the display constantly says charging......so frustrating

[@Rickmakes]

These monitors are for automotive batteries, which are lead acid. They likely aren't compatible with lithium.
