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:

1. 30mAh: 15.40mm X 10.10mm X 4.10mm
2. 160mAh: 20.30mm X 10.20mm X 4.10mm
3. 250mAh: 27.60mm X 9.05mm X 4.0mm
4. 350mAh: 31.70mm X 19.75mm X 4.40mm
5. 400mAh (Square design): 23.60mm X 16.90mm X 4.50mm
6. 400mAh (Narrow design): 46.80mm X 8.90mm X 4.80mm
7. 450mAh (Narrow design): 43.00mm X 9.40mm X 4.80mm
8. 500mAh: 37.50mm X 25.10mm X 3.95mm
9. 1000mAh: 49.40mm X 32.20mm X 4.10mm
10. 1,950mAh: 61.80mm X 43.40mm X 6.0mm
11. 3,000mAh: 64.80mm X 49.50mm X 4.90mm
12. 3,500mAh: 77.20mm X 63.10mm X 3.60mm

           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.
