Kitronik Polymer lithium Ion Battery LiPO 3.7v

Manufacturer: Kitronik

These 3.7V Polymer Lithium-Ion (LiPo) batteries provide a high power capacity in a very small lightweight package, making them ideal for many applications. They are often used in portable consumer products such as Bluetooth speakers and mobile phones. The batteries are supplied with 100mm leads terminated with a JST adapter cable.

These Polymer Lithium batteries come with a built-in protection circuit that protects against; overvoltage, 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.

These batteries do not 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. Lithium Polymer batteries require special charging circuits. Do not attempt to charge these with anything but a specialised Lithium Polymer charger.

Features:

Built-in protection circuit to prevent overcharging or discharging.

Built-in short circuit protection circuit.

Robust power source under extreme conditions (-10 to 60C).

Leads terminated with a JST connector.

Dimensions:

Length: 29mm.

Width: 25.5mm.

Thickness: 4mm.

Wire Length: 100mm.

Caution:

These batteries are capable of delivering high current output. If using conductive thread, a short in the circuit (between thread) could create sparks and heat. We recommend using coin cell holders and batteries for wearable projects.

When removing the connector from a socket do not pull it out using the connecting wires as this can damage the connector.

Neither the battery nor its protection circuit are waterproof, and if being used in an environment where water contact is possible or likely then the battery should be further protected.
