Wrong battery numbering has to be corrected
When come to substation for BMS installation, the most frequent frustration is to correct the numbering.
We have to go with standard. Wrong direction, wrong data.
Don’t worry, Sentry-6002NEMA has protection built in so the wrong direction won’t burn the board but you have to re-label all batteries as correct numbering and re-wire all cables. That may take you full day for a 60x2V string. So do check it before you start a installation!!!

6.2.2 Cell/Module installation and connections
j) For future identification, apply individual cell/module numbers in sequence beginning with number one at the most positive end of the battery. For parallel strings, the cells in each string should be numbered in the same polarity sequence starting with number one, and each string should be uniquely identified.

k) For future identification, apply individual cell numbers in sequence beginning with number one at the positive end of the battery; also add any required operating identification.
