So I have my 48V system built by a 4x 12.8v ZOOMS battery in series. Today I measured one was at 13.3V, and the other was at 13.9V after a month of use.
It seems they are getting more and more unbalanced over time.
Instead of buying a 12V battery charger and charging them one by one every few weeks, what is a better solution to this?
I am using Growatt, and it has a battery equalization option. Is that what I need?
I am also considering this item, but I really don't want PowMr: https://www.amazon.com/Battery-Equalizer-48V-Voltage-Balancer/dp/B07L8WKKC3
