From the shop's description

Polymer Li-Ion Single Cell Battery (3.7V, 300mAh) + Protection Board 60*20*30mm Lithium – Ion polymer batteries, or more briefly LiPo s are rechargeable batteries using lithium ion technology that can be recharged repeatedly. It is constructed from one to several electrochemical cells. Lithium ions migrate during discharge from the negative electrode through the electrolyte to the positive electrode, and then back again during the charging. Today this powerful, but yet simple technology is used in a number of applications – starting years ago with mobile telephones and laptops and now moving on to new wearable technologies such as smartwatches, headsets or fitness trackers.
