Xr bms cell balancing chip i.d.
-
I'm try to source the small chip on the XR/Pint bms, one cell group is not charging.
I externally charged the Xr battery pack, reinstalled the battery, ran it down to 50%, charged the board normally, but one cell group remained at 50% while the others went to almost 100%. Any ideas?
All I get read on the chip is "M8t"?
