Ok so I purchased 3 aolithium 12v 100ah batteries and are working just fine. I decided that I wanted to upgrade the bms in one of my batteries to have active balancing. I purchased the new version of the 100ah 8s bms. It's the new smaller version that just came out. Installation went just fine and fully charged my batteries and fully balanced my batteries with no issues. Next morning I noticed that my battery had dropped voltage to 13.3v. Found that to be quite low so charged again and left it overnight again with same results. I then fully charged my other two batteries with the factory jbd bms and next morning those were well over 14v by morning. I then decided the check how many mA the jk draws. With everything off and cells fully balanced, it draws 62mA. Checked my jbd with same settings and it's at 8mA.
So my question is, can this new jk bms really use this much power or do I have a defective bms.
