I didn't get the BMS as I stated in my first message. The experience I have with no BMS on my Gizmo for the past couple of years and the fact that this is a pack of 4 cells each that are accessible means that I'm confident I don't need an electronic BMS. I just very carefully bottom balanced them so they would each rest for several days at about 2.60V and then I charged them up and monitored the individual voltages at the end of charge and determined that 3.400V each average was well within the safe range for all the cells even if I left them hooked up to my power supply for a day. I stop mowing when the loaded voltage is at 20V and all of the cells bounce back over 3.00V so I know none of them were over discharged. Why would I need anything else?
