These 3.7V Polymer Lithium Ion (LiPo) batteries provide a high power capacity in a very small lightweight package. This makes 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 standard 2 pin JST-PH connector.

These 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.

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.

Though these cells are rated for discharge rates of up to 2.1A, due to the connecting wire and connector used we do not recommend exceeding a discharge rate of more than 1A.


  • Built in protection circuit to prevent over charging or discharging.
  • Built in short circuit protection circuit.
  • Robust power source under extreme conditions (-10 to 60C).
  • JST-PH connector.


  • 1 x Polymer Lithium Ion Battery – 1000mAh.


  • Maximum Length: 34.5mm.
  • Maximum Width: 6.2mm.
  • Maximum Height: 52mm.
  • Cable Length: 100mm (nominal).

Please note – We have had batteries delivered marked 950mAH – This is an error on marking & the batteries are still 1000mAH.
