Polymer Lithium Ion Battery (3.7V, 1Ah)
These are very slim, extremely lightweight batteries based on Lithium Ion chemistry. Each cell outputs a nominal 3.7V at 1000mAh! Comes terminated with a standard 2-pin JST-PH connector but be aware this connector has a 1mm pitch spacing between pins.
If you require a 2mm pitch connector so you can plug into a micro:bit etc then you can simply chop the 1mm connector of and solder on a 2mm connector instead.
These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.
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 that 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.
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.
