They are often used in portable consumer products such as Bluetooth speakers and mobile phones.\u003c\/p\u003e\n\u003cp\u003eThe batteries are supplied with 100mm leads terminated with a standard 2 pin JST connector.\u003c\/p\u003e\n\u003cp\u003eThese Polymer Lithium batteries come with a built in protection circuit which protects against; over voltage, over current, over discharge and also provides short circuit protection. When fully charged the battery will have a voltage of around 4.2V and when fully discharged the battery has a cut off voltage of 2.4V. \u003c\/p\u003e\n\u003cp\u003eThese batteries \u003c\/p\u003e\u003cstrong\u003edo not\u003c\/strong\u003e have a hard protective case. You should take care when housing the batteries in your design to ensure they have sufficient mechanical protection to protect the battery from any possible damage. If a battery does become damaged (dented, bent, etc) then it should not be used.\n\u003cp\u003eLithium Polymer batteries require special charging circuits.
