I have a 48 volt Club Car with 6 new 8 volt batteries last fall. I am using it to spray weed killer for food plots. I simply hooked the srayer accross one (1) battery. Yes it's a 12 volt sprayer but it seems to be working fine on 8 volts. My question is will the the battery pack equalize itself out or will this one battery become drained by itself, causing any problems? Is there a better way to hook up 12v accessories?
