30x New Helio 3.6v 2200mah 18650 Cells with PCB - $99/kWh

These batteries have never been installed or cycled, come with a PCB, and we test every cell on our professional testing equipment. All cells are testing 100% capacity and every cell is the same exact voltage. These are ready to be built into batteries.

The PCB is a single cell BMS. It protects from over charge, over discharge, and over current. It is like having a smart fuse on every cell. Doesn't get any safer than this. If you build these into a pack just remember you still want an overall BMS on your pack, the cell level BMS will protect each cell but you still want an overall BMS. You can spot weld these like normal cells and also they fit perfect in the regular 18650 cell holders because they are still the same width. They are just 2mm longer because of the circuit board.

Each cell has what appears to be 2a BMS PCB. It is certainly a 1s BMS but we are just sure exactly what the amp rating is. Based on the nickel strip it appears to be able to carry up to 2a current. Recommended max continuous charge is 1a and max continuous discharge is 2a.

These are perfect capacity cells. Likely not great for ebikes or drill batteries. Any application that require a high C rate you should use high amp rated cells.

Fully charged voltage is 4.2v and fully discharged voltage is 2.8v.
