Carbage

The voltage settled down a bit more, I waited for it to finish settling before I turned on a load so I could get an accurate reading...

And now that it's rested for a few minutes, the voltages have landed here. Seems very low to me..

Well it decided it's charged. Claiming it has 135ah of capacity, if so that would be very impressive from a 100ah rated Chinese battery...

Another reason for the voltage dip could be the temperature. The cells were at just 9.3C in the first screen shot and it warmed up to...

Awesome news. I will keep this post updated, app claims 4 hours of charging remaining (can only charge at 25a with my little Honda...

That's the reason voltage alone is not a good indicator of SOC til it reaches the knee.

That’s 100% normal. Once it reaches the target voltage (or if charging is interrupted), it will settle down to its resting voltage.

So the app is stating that after charging for the last 2 hours or so, that I've actually gone down slightly in voltage, but the capacity...

Glad you got the App working .... That will help a lot.

Everything is charging. The battery was most definitely dead, but it is indeed 16s. It was down to 48v. Set constant charging to 57.6v...

I will check on that as well. Hopefully I can find some sort of monitoring, and get a bunch of answers for us 😁

Sorry, that was me, I got it mixed up with another thread I was helping on. Even with one battery, I would hope it's output drops less...

It will run fine for a few cycles after the battery is charged, it's just when the battery gets down to around 50 volts. Around that...

I think there is a misunderstanding. I only have a single 100ah 48 battery. But I will put charging up to 16s, as you recommended, and...

Awesome. Then I will do some quick minimum checks, because I do suspect something is up (a bad cell causing a low string, or a poor...

No the battery will not be damaged however you might end up getting a low voltage disconnect depending on how far the voltage droops...

Okay, so if that's the case, then my original question; will the battery get damaged if it goes under the minimum recommended voltage...

Battery voltage droop under load as opposed to voltage drop due to resistance between battery and load can confuse people. The capacity...

Noted. I will look into the app, although I think I need a separate module it did not come with for that. I'll find out. I will also...

Specs for that show it should handle 100A. Note the voltage before and after adding the load. If it has Bluetooth, maybe post a pic...
