Hi everybody.
We have a 24V to 220V UPS system including 4 x 12V 250Ah Gel batteties.
I am wondering if it's good to put a connection like the red one in the attached diagram, because I think it balances the voltages of each of the two parallel batteries.
I'm saying that because I noticed one time in a 48V UPS system that the voltage of one battery of a four series bank was less than the others by about 2V, maybe because of a bad cell.
Theoretically and practically what doea this red connection changes?
