Hi everyone,
Need some help with my battery bank. It's just about 5 months old, and at the moment is start dropping voltage very quickly.
I'm have 330w solar panels, 60a MrPow charging controller, 280ah 4s eve prismatic cells, and 80a BMS.
So solar charger is showing full changed battery, but soon like I'm trying to use any electronic devices (light for example) voltage drops from 13.6v to 12v in 10-15 minutes time....
If trying to start some more powerful devices (120w water heater for example) BMS shut down the battery.
I'm believe it's just something wrong with connection or just 1 cells need to be replacing.
But I'm not electrician so if someone can recognise a problem, I'm be very appreciated for help.
Thank you.
