Battery Series Voltage Difference
Looking for theories/reasons why batteries 3&4 have such different voltages in this drawing. The difference stays consistent at different voltages and stayed about 0.3v different during a 3-hr equalization charge.
Thinking that somehow it was the jumper cable between the 2, I took it off and cleaned and tested its ohms. With the jumper off the voltage of 3&4 became the same, but they went back to having the difference after reinstalling.
Don't blow air up my rear, be useful and blow it at the sails!
