Earlier this year d8veh took me through balancing the cells of my 36v 15ah lithium battery, I got it up to 41 volts
and was happy with that.
I balanced it using a 5v usb cable through the balance wires on the BMS, I kept checking it for a couple of weeks and it stayed at that voltage, so I decided to put it away for a month or so till the weather improved.
I kept it in a drawer in my garage, wrapped in bubble wrap.
Yesterday I got it out and measured the voltage at the bottom, and it was 32 volts, I was a bit taken back by that much drop.
I put it on charge for about six hours and it has remained the same, I think it requires charging again through the balance leads, I have an imax B6 that a friend gave me that can charge six of the cells at once, but I require a bit of help in where to put the main charging leads, and attach to the balance leads.
I have some seven wire leads.
hoping for some help.
