Lithium Ion Polymer Battery 3.7V 500mAh Rechargeable, Lithium Ion Polymer Battery 3.7V 500mAh RechargeableProduct Note: Battery may be marked LP503035 or LJ503035, but they are the same. Lithium ion polymer, also known as 'lipo' or 'lipoly', batteries are compact and powerful. The output ranges from 4.2V at full capacity to 3.7V. This battery has a capacity of 500mAh for a total of about 1.9 Wh, so it's good for small, low-power projects. The batteries come pre-attached with a genuine 2-pin JST-PH connector (2mm pitch) as shown 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 very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 500mA or less. We suggest a Micro Lipo charger with a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge. Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1C or even less - 100 to 500mA is a good rate and is available from any USB port if using a USB-powered charger. 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 possibility of short circuits. 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.
