Not to skew things but on solar with 800 watts. All power dropped out so I reset the charge controller as per mfg and put the 4 Lion Safari UT 1300 LiPo batteries on a charger. This was the solar tech recommended fix. Everything was good and all of a sudden everything dropped out. No 12v just like before.
So, checking each battery by pressing the battery button on top each battery will show a solid green light at 0-10%. One battery has the same indication but the light flashes.
Maybe this battery is bad? Since they are all connected maybe this one battery has a brain issue? My system said it was an excessive discharge. I am assuming the one battery is taking out the other batteries?
Thoughts anyone?

I may be misunderstanding part of your post. I read about those particular batteries and the button on the top is pressed and released, followed by one of five possible lights illuminating, indicating state of charge. Continued pressing of the button until the light goes out will reset the battery.

You state the light is for 0-10%, and one battery only blinks at that level. Unless I am misunderstanding, all the batteries are near depletion, with one possibly bad. They appear not to be getting adequate charge. If one is bad, it will draw down the others and lion batteries tend to shut off immediately rather than gradually fade out like flooded cells. My guess is this is what you are experiencing.

You are correct, state of charge was well over 12.6 but all of a sudden drops off. One press will indicate charge status. 3 seconds resets the batteries but it should give me an indication that they reset. My thoughts are this one battery is fine the all of a sudden discharges taking the other batteries with it.

A flashing led indicates a dead battery. You need to charge it again, take it off the charger for a couple hours, then test it again. It should maintain about 13.4 VDC. Why aren't your batteries being charged by the Solar or the inverter/charger or converter? BTW, 800 watts of solar isn't much for charging batteries, especially 4 lithium batteries. That's only 66 amps at peak, and I doubt you are operating at peak.

The MPPT is connected to the battery bank so I assume they are charging. BTW , this happened while on a separate charger. Checking the suspect battery it now shows the same indication as the other 3, a solid single led. I appreciate your input! With a residential fridge it might be too much of a draw as well as the other (microwave) components.
