okay I will test it tonight when i disconnect the postive lead should I also be disconnecting all the batteries?

there is no flickering of lights at all. its the indicator lights on the back that always stay where 50% would be. I tested each battery it was doing that when the batteries were new as well.

About a month ago I got a 48v Meanwell TN3000 and 4x 100ah 12v lead acid batteries. It has lasted through loadshedding with no issues. I do have some oddities that I noticed. When it is on bypass 2 of the 4 battery indicator lights are lit up not all 4. When the power goes out all 4 are lit up. I also noticed every on average 1 minute and 30 seconds it turns on the fans and charges for about 3 seconds before it turns off. It does this constantly every minute is this behavior okay? I have checked the terminals and I do have a multimeter to test if needed but I would appreciate if someone that knows a bit more than I do can perhaps tell me if I am worried for nothing?
