Please check your cell polarity with a volt meter before connecting the BMS!
This type of cell has been shipped by other suppliers with the labels on backwards.
We have seen an excessive number of BMSs ruined recently because the customer’s cells had the labels on backwards
Most cheap prismatic cells on the market have black plastic on the POSITIVE terminals and beige plastic on the NEGATIVE terminals.
Note: This is not our product. Overkill Solar has never supplied this type of cell.

Thanks for the heads up!!!
