Description 

Allrun rectangle lipo battery is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. Allrun LiPo batteries are thin, light, and powerful. The normal voltage is 3.7V,  031120 LiPo battery has a capacity of 40mAh for a total of 0.148 Wh. If you need a smaller or bigger LiPo battery, we also have 30mAh, 300mAh, and so on, please do not hesitate to contact us for more details. 

031120 lithium polymer battery pack includes a PCM that keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut out when the charging voltage is over 4.2V and the discharge voltage is less than 2.75V. PCM will also protect against output shorts. However, even with this protection, it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them at a rate of 40mA or less. 

Applications

Rectangle Lithium-Ion polymer batteries are rechargeable batteries using lithium-ion technology that can be recharged repeatedly. It is constructed from one to several electrochemical cells. Lithium ions migrate during discharge from the negative electrode through the electrolyte to the positive electrode, and then back again during the charging. Today this powerful technology is used in a number of applications, such as

-Wearable devices (smart watch, smart clothing, heating apparel, bluetooth headset, etc.)
-Medical Devices (portable X-ray camera, insulin pump, blood pressure devices, etc.)
-IoT and Smart Home products( smart lock, doorbell camera, smart faucet, security monitor, BLE credit card, etc.)
-Industrial &Consumer electronics(portable electronic devices, scanners, sensing timers, timer systems, vaccination emergency lights, etc)
 

Lithium polymer battery cells are tailor-made dimensions based on the customer's design, we have only listed part of the models below for your kind reference. Please contact us for more details regarding your specified project.

Rectangle LiPO Battery Safety Notes

1. Avoid using lead-acid, NiCd, or NiMH chargers.
2. Be careful not to abuse these batteries, such as shorting, bending, crushing, or puncturing them.
3. Charge and use should never be left unattended.
4. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or the possibility of short circuits.
5. Do not use or leave the battery at very high-temperature conditions(for example, strong direct sunlight or a vehicle in extremely hot conditions). Otherwise, it can overheat or fire, or its performance will degenerate and its service life will be decreased.
