Lithium Polymer LiPo Battery (3.7V, Single-Cell) Lithium Polymer LiPo Battery (3.7V, Single-Cell)
Lithium Polymer LiPo Battery (3.7V, Single-Cell) from ₹ 99.99 ₹ 199.00
We offer a wide range of single cell Lithium ion polymer (also known as 'lipo' or 'lipoly') batteries, that are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.2V. While the nominal voltage of the battery remains at 3.7V, which is also a safe voltage to store the battery at.  The batteries have come with either a 2-pin JST-PH connector or "no connector" and include the necessary protection circuitry. The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use), which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is important to use a LiIon/LiPoly constant-voltage/constant-current charger to recharge and at a rate of 2A or less (500mA is best). We suggest our Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge. NOTE: We can provide custom LiPo batteries for BULK orders on demand. Please contact us for a quote.  Physical Dimensions In order to facilitate accurate use of these batteries, and help the use with optimum enclosure design, we are providing below, the right cube size needed to house each battery: 30mAh: 15.40mm X 10.10mm X 4.10mm 160mAh: 20.30mm X 10.20mm X 4.10mm 250mAh: 27.60mm X 9.05mm X 4.0mm 350mAh: 31.70mm X 19.75mm X 4.40mm 400mAh (Square design): 30.60mm X 19.60mm X 4.50mm 400mAh (Narrow design): 46.80mm X 8.90mm X 4.80mm 450mAh (Narrow design): 43.00mm X 9.40mm X 4.80mm 500mAh: 37.50mm X 25.10mm X 3.95mm 1000mAh: 49.40mm X 32.20mm X 4.10mm 1,950mAh: 61.80mm X 43.40mm X 6.0mm 3,000mAh: 64.80mm X 49.50mm X 4.90mm 3,500mAh: 77.20mm X 63.10mm X 3.60mm     Tutorial

Flat Top 18650 Li-Ion Battery without Protection (3.7V) - BIS Certified from ₹ 99.99 ₹ 150.00
These lithium-ion batteries come in a variety of configurations and capacities. The battery with a protection circuit provides over-voltage, under-voltage, and over-current protection. Yet, it is slim and easy to fit into many project cases. These batteries do not come with protection circuitry. It is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 0.5C (1 Amp) or less and add a separate protection circuitry.   If you want batteries with protection, you can buy one here!Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush, or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or the possibility of short circuits. Polarity matches all Adafruit LiPoly/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery. As with all Lithium-ion polymer batteries and with any power source - they should be used by experts who are comfortable working with power supplies Specifications 2600 mAh  Nominal Capacity: 2600 mAh Minimum Capacity: 2500 mAh Nominal Voltage: 3.7V Charge Voltage: 4.2V Continuous Discharge Current (max.): 5A Operating Temperature: 0℃ - 45℃ Internal Resistance ≤ 40mΩ @ 1kHz AC 2000 mAh Nominal Capacity: 2000 mAh Minimum Capacity: 1900 mAh Nominal Voltage: 3.7V Charge Voltage: 4.2V Continuous Discharge Current (max.): 3.8A Operating Temperature: 0℃ - 45℃ Internal Resistance ≤ 40mΩ @ 1kHz AC 1500 mAh Flat Top Nominal Capacity: 1500 mAh Minimum Capacity: 1450 mAh Nominal Voltage: 3.7V Charge Voltage: 4.2V Maximum Discharge Current: 1.5A Operating Temperature: 0℃ - 45℃ Internal Resistance ≤ 20mΩ @ 1kHz AC

This lithium ion battery with capacities of 500mAh and 700mAh.  It is slim and easy to fit into many project cases. The batteries are unprotected and best work with out 16340 Battery Shield and 16340 Arduino Shield. Like most lithium-ion packs, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1/2C or even less - 0.5A max in this case. Of course, you can charge at a lower rate - it'll just take a little longer to fill up.Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush or puncture. Never charge or use unattended.
