One thing I noticed when I was running my battery down trying to reach the BB low voltage disconnect,, I was paying attention to my capacity monitor the whole time and when it got down to 12% soc I was actually looking at the monitor and all the sudden it dropped like a rock from 12% soc to 0% soc instantly.
At that point I started thinking that I must be close to the battery shutting down.
Nope , it took another hour and a half until the battery shut down , volts were 9.3 volts when the battery shutdown.
I'm not saying my monitor is correct just what I witnessed.
That there is the knee. They'll give their all till....lights out.
Yeah but it went lights out a hour and a half after my Soc meter read 0% soc?
I was thinking that my soc % monitor should read 0% at least close to the time the lights go out.
Shouldn't the battery have been at 0ah when the lights went out?
That's because your meter isn't properly synced to the batteries and most likely why BLF13 is going bananas with ah out/ ah in being so far out of wack.
Maybe it's a cheap meter, that shunt looked cheap in the video, maybe Chinglish count is different and programmed it wrong? ;)
Try reprogramming it or think about a different meter, many folks seem to like the Victron stuff.
Either way BB bms will protect the battery if the voltage gets to low or high.
