3s 11.1v 2200mah 18650 Battery with BMS

These batteries are checked for good voltage and come with a BMS. They were recovered from power window blinds/shades.

Awesome value here. You can parallel them together or just recover the cells.

Fully charged pack is 12.6v (4.2v/cell)
Fully discharged pack is 8.4v (2.8v/cell)
Recommended max charge rate 1a
Recommended max discharge rate 2a

The BMS appears to be a 2a rated BMS but that is not confirmed. It may be a 3a or 5a BMS. If you need a lower voltage battery like this, maybe for a 12v low power system, this would be a great deal at this price. The battery comes in a plastic case that snaps open easily too.

You can charge and discharge through the same red/black wires.
