Hello,

is there a source, where I could purchase 3 cells for replacement in my battery pack (48V12Ah) as one of the 13 groups shows noticeably lower voltage and it seems to degrade the performance of the whole pack.

Not sure about the repair itself, as the cells are "welded" to the connecting strips, but first I am looking at the possibility to source the cells.

Many thanks,
Pavel
