3.7v 2250mah Panasonic/Sanyo 18650 cells with PCB
These cells are perfect for battery building because they come with a BMS already installed on it. All cells are manufactured by Panasonic. Some are the CGR18650CG and some are the UR18650A cells which both are made by Panasonic. They are 2250mah cells.
The white wire is not needed for your project, just use the red and black wires as your positive and negative. You can build batteries with just the wires. Or you can salvage the 1s BMS off the cells, use the cells, then sell the BMS on Ebay and likely recoup most of the money for the purchase.
