New 2021 Module with Converter + 3x Power 18650 Cells

We have a small amount of these packs that have 3x 2100mah cells that are rated for up to 22a discharge. They are excellent power cells. We are selling these for cell recovery however if you know about the circuit board inside there is definitely a buck/boost converter built in.

Please refer to the photos.

The module we opened for the photo the sticker says 2021 so they are fresh packs that are still in the original box. It says input 24-35v and output 21v. Perhaps this is useful for you but we are just selling for the value of 3x brand new LGAAHD2C1865 3.6v 2100mah 18650 cells that can discharge up to 22a (10c).
