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 standard 2 pin JST 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.

Features:

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 connector.
Maximum discharge rate of 880mA.

Dimensions:

Maximum Length: 35mm.
Maximum Width: 23mm.
Maximum Height: 5.2mm.
Cable Length: 104mm.

Requires:

Suitable charger such as our LiPo Charger/Booster.

Caution:

These batteries are capable of delivery a 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 JST connector from a socket do not pull it out using the connecting wires as this can damage the connector.
Neither the battery or its protection circuit are water proof, and if being used in an environment where water contact is possible or likely then the battery should be further protected.

Q:

Just received one in my order - VERY quick delivery Many Thanks What is the connector on the cable called? - i assumed it was a JST-PH but it doesn't connect to my device which has JST-PH on board. So i need to order replacement connector or adapt it somehow - not a problem if I can identify the connector ? Regards

Asked by: Jason Davies

A:

HI Cullen Wow quick reply - almost as quick as your delivery! Thanks for the info - will am awaiting reply from manufacturer of device as according to the spec sheet it should have the correct socket to take that connector but it just wont fit. I have since tested the connector on the battery you supplied with another device & it fits fine so guessing the installed socket is not correct or faulty. Not the biggest problem and am sure i can make ( Bodge ) something ! Stay Safe Jason

Q:

Can this battery be used to power 5V & 12V LED strip lights? Also, if I was using it with Colour Changing 5mm Diffused LED - 750mCd - Code: 3527, how would I connect the LED to the battery? Thanks

Asked by: Ayesha

A:

Hi, this will not be able to power that however the product codes 2248 or 2259 can be used in enough quantities, each of those batteries would provide 1.5v (so three for a 5v and 8 for a 12v application)
