February 25, 20197 yr Hi guys. I am using 8 210ah 6v lead acid batteries to make up my 48v bank. I have installed them with a voltmeter on each battery just to make sure that all off the batteries are in working order and to check the voltages for interest sake. My question is, what would be considered an exeptable difference in voltages between the batteries?
February 25, 20197 yr Hi Lionheart! You can accept 10 mV per cell, so if your batteries are three cell, a good value is 30 mV.
February 25, 20197 yr Author Thank you. So that means 0.03 volt per battery? Mine differs a bit more than that, but also, I did not buy very expensive, accurate volt meters. When fully charged, the difference between the lowest and highest battery is 0.09 volt.

But, in my opinión and if It is possible, It is better to control density of each cell, when It is fully charged. Edited February 25, 20197 yr by Javi Martínez
