Looking for some advise on how to reset the cycle counter. Currently showing 121. I attempted to put cells in right away and let unit charge but that ended in disaster so I went to top balance them with jk bms and Parralel connecting the cells for 2 days. But would like to get the cycle counter down to 0 or 1 as the BMS is doing its learning process at moment.
 
You can't?! That's a bummer It seems like there should be a way. Like maybe reflashing it with some kind of firmware possibly?
 
If you still want to reset the counter I discovered how to do it by accident last night - in BMS-STUDIO, if you go to the "switch control" tab, on the left hand side there are options to turn the charge/discharge FETs on, turn power off etc, the bottom one is called "reset system" or something - this resets the counter.
 
Its posible to reset it with the PC software, both V2.0(V16, 10e etc.) and V3.0

I have done it in both variants. Its just tricky to find.
V2.0 -> SN menu if i remember correct
V3.0 -> Switch control ->System reset, as Milky_pete say
