7.4V 5400mAh Li-Ion Battery for use with the Multi-Voltage Base Layer, Socks, Gloves and/or Glove Liners. This does not have a Controller in it and it is assumed that you already have the Base Layer with the Multi-Voltage Controller. Nor does it come with a Belt Pouch.
This is only the battery. If you do not have the charger, then you need to order that also!
